Chapter 1 The BPX Switch: Functional Overview New with Release 9.
Chapter 1 The BPX Switch: Functional Overview New with Release 9.3 • Priority Bumping This feature allows connections for both BPX and IGX that are classified as more important (via COS value) to bump existing connections that are of lesser importance when there are insufficient resources (such as bandwidth) to route these important connections due to trunk failures in the network. You turn on priority bumping, change parameters, and view the statistics by using the command cnfbpparm.
Chapter 1 The BPX Switch: Functional Overview Discontinued • 800 Board Level Revision Number The board level revision number (also known as the Manufacturing 800 number) provides the maximum information possible about a given card, which assists in troubleshooting. This enables Cisco Customer Service to remotely identify the board level revision number without physically removing the card from the slot.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation The BPX Switch with MGX 8220 Shelves Many network locations have increasing bandwidth requirements due to emerging applications and the confluence of voice, data, and video digital communications. To meet these requirements, you can overlay your existing narrowband networks with a backbone of BPX switches to utilize the high-speed connectivity of the BPX switch operating at up to 19.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation With Label Switching the complete analysis of the Layer 3 header is performed only once: at the edge label switch router (LSR) which is located at each edge of the network. At this location, the Layer 3 header is mapped into a fixed length label, called a label. At each router across the network, only the label need be examined in the incoming cell or packet in order to send the cell or packet on its way across the network.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation Virtual Private Networks This section is a brief description of the BPX switch’s support for Virtual Private Networks (VPN). For additional information, refer to the Cisco MPLS Controller Software Configuration Guide Conventional VPNs that use dedicated lease lines or Frame Relay Private Virtual Circuits (PVC) and a meshed network (Figure 1-2) provide many advantages, but typically have been limited in efficiency and flexibility.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation – No VPN knowledge in core, – No need for separate VC mesh per VPN • Highly Scalable • Easy to add new sites Configure one site on one edge router or switch and network automatically does the rest. • Traffic Separation in MPLS Each packet has a label identifying the destination VPN and customer site, providing same level of privacy as Frame Relay.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation Network Interworking Part A of Figure 1-4 shows typical Frame Relay to network interworking. In this example, a Frame Relay connection is transported across an ATM network, and the interworking function is performed by both ends of the ATM network. These are typical configurations: • IGX switch Frame Relay (shelf/feeder) to IGX switch Frame Relay (either routing node or shelf/feeder). • MGX 8220 Frame Relay to MGX 8220 Frame Relay.

Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation Tier Network Definitions Annex G Annex G is a bi-directional protocol, defined in Recommendation Q.2931. It is used for monitoring the status of connections across a UNI interface. Tiered Networks use the Annex G protocol to pass connection status information between a Hub Node and attached interface shelf. BPX Routing Hub A BPX node in the routing network which has attached interface shelves. Also referred to as a hub node or BPX hub.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation Use the Cisco WAN Manager Connection Manager to configure and control these individual segments as a single end-to-end connection. Interface shelves are attached to the routing network via a BPX routing hub using a BXM trunk (T3/E3 or OC-3) or BNI trunk (T3/E3). The connection segments within the routing network are terminated on the BNI feeder trunks.
Chapter 1 The BPX Switch: Functional Overview BPX Switch Operation • Local and Remote Loopbacks Connection local and remote loopbacks are managed at the user interface of the FRP endpoint routing node or interface shelf. Remote loopbacks are not supported for DAX connections. The command addlocrmtlp supports remote loopbacks at FRP DAX endpoints. • Testcon and Testdly Tstcon is supported at the FRP endpoints in a non-integrated fashion and is limited to a pass/fail loopback test.
Chapter 1 The BPX Switch: Functional Overview Traffic and Congestion Management Figure 1-8 Virtual Trunking Example Cisco sub-network Cisco sub-network ATM-UNI ATM-UNI Leased line (backup) ATM-UNI ATM-UNI Virtual trunk Leased line Cisco sub-network H8227 Cisco sub-network Public ATM Network Traffic and Congestion Management The BPX switch provides ATM standard traffic and congestion management per ATM Forum TM 4.0 using BXM cards.
Chapter 1 The BPX Switch: Functional Overview Traffic and Congestion Management • ABR Standard with VSVD Congestion control using RM cells and supported by BXM cards on the BPX Switch. • Optimized Bandwidth Management (formerly ForeSight) An end-to-end closed loop rate based congestion control algorithm that dynamically adjusts the service rate of VC queues based on network congestion feedback.
Chapter 1 The BPX Switch: Functional Overview Traffic and Congestion Management These class of service parameters are based on the standards-based Quality of Service parameters and are software programmable by the user. Automatic Routing Management With Automatic Routing Management (formerly referred to as AutoRoute), connections in Cisco WAN switching networks are added if there is sufficient bandwidth across the network and are automatically routed when they are added.
Chapter 1 The BPX Switch: Functional Overview Traffic and Congestion Management ABR Standard with VSVD Congestion Control The BPX/IGX switch networks provide a choice of two dynamic rate based congestion control methods, ABR with VSVD and Optimized Bandwidth Management (ForeSight). This section describes Standard ABR with VSVD. Note ABR with VSVD is an optional feature that must be purchased and enabled on a single node for the entire network.
Chapter 1 The BPX Switch: Functional Overview Network Management If the network reaches full utilization, ForeSight detects this and quickly acts to reduce the extra bandwidth allocated to the active PVCs. ForeSight reacts quickly to network loading in order to prevent dropped packets. Periodically, each node automatically measures the delay experienced along a Frame Relay PVC. This delay factor is used in calculating the ForeSight algorithm.
Chapter 1 The BPX Switch: Functional Overview Network Management • StrataSphere Modeler Network modeling tool used for preliminary design of new networks and for analysis and modification studies of existing networks. • StrataSphere Adaptor Exports network modeling information to external third party modeling systems. • SNMP Service Agent A service agent that provides an interface for automated provisioning and fault management to customers or Operations Support Systems (OSS).
Chapter 1 The BPX Switch: Functional Overview Network Management • Equipment Management The Cisco WAN Manager Equipment Manager provides the ability to perform equipment management functions such as adding lines and ports on a Cisco MGX 8220 edge concentrator shelf. • Alarm Reporting/Event Log Cisco WAN Manager displays major and minor alarm status on its topology screen for all nodes in a network.
Chapter 1 The BPX Switch: Functional Overview Network Management Service Interfaces Service interfaces connect ATM customer equipment to the BPX switch. ATM User-to-Network Interfaces (UNI) and ATM Network-to-Network Interfaces (NNI) terminate on the ATM Service Interface (ASI) cards and on BXM T3/E3, OC-3, and OC-12 cards configured for as service interfaces (UNI access mode). The BXM T3/E3 card supports the standard T3/E3 interfaces. The BXM-155 cards support SMF, SMFLR, and MMF physical interfaces.
Chapter 1 The BPX Switch: Functional Overview Switch Software Description A clock output allows synchronizing an adjacent IGX switch or other network device to the BPX switch and the network. In nodes equipped with optional redundancy, the standby hardware is locked to the active hardware to minimize system disruption during system switchovers.
Chapter 1 The BPX Switch: Functional Overview Switch Software Description • Alternate Routing The system software automatically reroutes a failed connection. The system software uses these criteria when it establishes an automatic route for a connection: • Selects the most direct route between two nodes. • Selects unloaded lines that can handle the increased traffic of additional connections.
Chapter 1 The BPX Switch: Functional Overview Switch Software Description Table 1-1 Routing Group Configuration Example (continued) Routing group Connection cell loading 3 80–89 4 90–99 5 101–109 6 110–119 7 120–129 8 130–139 9 140 and up Cost-Based Connection Routing In standard AutoRoute, the path with the fewest number of hops to the destination node is chosen as the best route. Cost-based route selection uses an administrative trunk cost routing metric.
Chapter 1 The BPX Switch: Functional Overview Switch Software Description Enabling cost-based route selection automatically enables cache usage. Enabling Hop-Based Route Selection automatically disables cache usage. Cache usage can also be independently enabled or disabled for both types of route selection. • On-Demand Lowest Cost Route Determination On-demand routing chooses the current lowest cost route to the destination node. This lowest cost route is bounded by the maximum route length of 10 hops.

Disabling cost-based route selection automatically disables cache usage. Cache usage may also be independently enabled or disabled. • cnftrk Configures the administrative cost for a trunk. Both physical and virtual trunks have the cost attribute. Each trunk has a cost ranging from 1 (lowest) to 50 (highest). The default cost is 10 upon trunk activation.
Chapter 1 The BPX Switch: Functional Overview Switch Availability Switch Availability Cisco WAN hardware and software components are designed to provide a switch availability in excess of 99.99%. Network availability will be impacted by link failure, which has a higher probability of occurrence than equipment failure. Because of this, Cisco WAN network switches are designed so that connections are automatically rerouted around network trunk failures, often before users detect a problem.
Chapter 1 The BPX Switch: Functional Overview Switch Availability An Alarm, Status, and Monitor card collects all the node hardware status conditions and reports it using front panel LED indicators and alarm closures. Indicators are provided for major alarm, minor alarm, ACO, power supply status, and alarm history. Alarm relay contact closures for major and minor alarms are available from each node through a 15-pin D-type connector for forwarding to a site alarm system.

C H A P T E R 3 BPX Switch Common Core Components This chapter describes theBPX Switch’s common core hardware components: • Broadband Controller Card (BCCs) • 19.2 Gbps Operation with the BCC-4V • Alarm/Status Monitor Card • BPX Switch StrataBus 9.6 and 19.
Chapter 3 BPX Switch Common Core Components Broadband Controller Card (BCCs) Broadband Controller Card (BCCs) The Broadband Controller Card is a microprocessor-based system controller and is used to control the overall operation of the BPX switch. The controller card is a front card that is usually equipped as a redundant pair. Slots number 7 and number 8 are reserved for the primary and secondary (standby) broadband controller cards.
Chapter 3 BPX Switch Common Core Components Broadband Controller Card (BCCs) The BCC-4V provides a 16 x 32 cross-point architecture that increases the peak switching capacity of the BPX switch to 19.2 Gbps, with a sustained non-blocking throughput of 9.6 Gbps. Features The Broadband Controller Card performs these major system functions: • Runs the system software for controlling, configuring, diagnosing, and monitoring the BPX switch.
Chapter 3 BPX Switch Common Core Components Broadband Controller Card (BCCs) The arbiter polls each card to see if it has data to transmit. It then configures the crosspoint switching matrix to make the connection between the two cards. Each connection is unidirectional and has a capacity of 800 Mbps (616.7 Mbps for cell traffic plus the frame overhead). Only one connection at a time is allowed to an individual card.

Chapter 3 BPX Switch Common Core Components Alarm/Status Monitor Card The Cisco WAN Manager NMS is connected to the LAN port on the BCC backcards. When control is provided via an Ethernet interface, you configure the node IP address by using the cnflan command for the BPX switch. For redundancy, also configure the LAN ports on both BCC back cards, each connected to an AUI adapter. The LAN port of the primary Broadband Control Card is active.
Chapter 3 BPX Switch Common Core Components Alarm/Status Monitor Card • Fan and temperature monitor Each of the three cooling fans is monitored by the fan monitor circuit which forwards a warning to the BPX switch system software if any fan falls below a preset RPM. Cabinet internal temperature is also monitored by the ASM which sends the temperature to the system software to be displayed on the NMS terminal. The range that can be displayed is 0 degrees to 60 degrees Centigrade. • Card detection.

Chapter 4 BNI (Trunk) Cards Broadband Network Interface Cards (BNI-T3 and BNI-E3) In the BNI-3E3 the PLPP is replaced by a G.804 framer. The E3 framer obtains end-to-end synchronization on the Frame Alignment bytes. And a E3 transmitter/receiver replaces the DS3 transmitter/receiver for the BNI-3E3. Another major BNI function is queuing of the ATM cells waiting to be transmitted to the network trunk. This is controlled by the Queue Service Engine.
Chapter 4 BNI (Trunk) Cards Broadband Network Interface Cards (BNI-T3 and BNI-E3) • A digital loopback capability on the BNI-3T3 to the PLPP processor This is used for the internal self test to basically check the operation of the signal processor. When a trunk has been assigned to a BNI card but is not yet activated (upped), it is put in a loopback mode and a diagnostic test is continuously performed. This loopback is disruptive so it cannot be performed on a card that has an active trunk.

Chapter 18 Configuring Trunks and Adding Interface Shelves Configuring Trunks You can configure port, routing trunk, and feeder trunk interfaces simultaneously on a slot containing a BXM card. For example, you can up port 1 on a BXM slot as a trunk interface while also upping port 2 as a line interface. For BXM cards, you do not need to upgrade the firmware.
Chapter 18 Configuring Trunks and Adding Interface Shelves Configuring Trunks The parameters that you can change without first deleting the trunk are: • Restrict Control Card traffic (“PCC restrict”) • Pass sync • Loop clock • Statistical reserve • Bursty data peak speed • Bursty data peak average frame • Idle Code (reconfigurable for trunk and line) • User traffic • Maximum PVC Channels • Trunk Partitions SVC/PVC • DS0 Map (IGX only, as of Release 9.
Chapter 18 Configuring Trunks and Adding Interface Shelves Configuring Trunks To display the current trunk parameters, use dsptrkcnf. If you can make all the needed parameter changes without deleting the trunk, execute cnftrk. Use cnftrk at both ends of the trunk. To change parameters that require you to first delete the trunk: Step 1 Delete the trunk by executing deltrk at one end of the trunk. Step 2 Execute cnftrk at both ends of the trunk to reconfigure parameters.
Chapter 18 Configuring Trunks and Adding Interface Shelves Adding an Interface Shelf • dspnw Displays all trunks for each node in a domain. • prtnw Prints all trunks for each node in a domain. Adding an Interface Shelf An interface shelf is a non-routing device that drives ATM cells to and from a BPX or IGX routing hub in a tiered network. (An interface shelf is also sometimes referred to as a feeder shelf.
C H A P T E R 19 Configuring Circuit Lines A circuit line is the physical line that carries data, voice, Frame Relay, or ATM traffic between a BPX node (or IGX node) and customer premises equipment. Each piece of customer premises equipment is attached to a node through a circuit line. You must first establish or “up” a card by using the upcd command, before you can “up” and configure a circuit line on that card.

Chapter 21 Configuring ATM Connections Traffic Management Overview Standard Available Bit Rate Standard ABR uses RM (Resource Management) cells to carry feedback information back to the connection’s source from the connection’s destination. ABR sources periodically interleave RM cells into the data they are transmitting. These RM cells are called forward RM cells because they travel in the same direction as the data.

Chapter 21 Configuring ATM Connections ATM Connection Requirements You can add ATM connections by using either the Cisco WAN Manager Connection Manager or a node’s command line interface (CLI). Typically, the Cisco WAN Manager Connection Manager is the preferred method because it has an easy to use GUI interface. The CLI may be the method of choice in some special cases or during initial node setup for local nodes.

Chapter 21 Configuring ATM Connections ATM Connection Flow ATM Connection Flow ATM Connection Flow through the BPX The BPX supports the standard ATM service types, CBR, rt-VBR, nrt-VBR, ABR, and UBR.
Chapter 21 Configuring ATM Connections ATM Connection Flow Network queues buffer the data at the trunk interfaces throughout the network according to the connection’s class of service. Service classes are defined by standards-based QoS. Classes can consist of the five service classes defined in the ATM standards as well as multiple sub-classes to each of these classes. Classes can range from constant bit rate services with minimal cell delay variation to variable bit rates with less stringent cell delay.
Chapter 21 Configuring ATM Connections ATM Connection Flow Note For a description of traffic shaping on CBR, rt-VBR, nrt-VBR, and UBR connections, refer to the section later in this chapter, Traffic Shaping for CBR, rt-VBR, nrt-VBR, and UBR, page 21-13. Egress to Network via BXM 10 In this example, ATM cells destined for BPX 2 are applied via the BCC crosspoint switch and BPX backplane to BXM 10 and out to the network.

Chapter 21 Configuring ATM Connections ATM Connection Flow Figure 21-4 shows an example of traffic shaping. In this example, port 1 is configured to perform traffic shaping. Note that all the ATM cells regardless of class of service pass through the VC queues before leaving the card when traffic shaping is enabled. In the example, port 2 is not configured for traffic shaping, and only the ABR traffic with FCES (flow control external segment) passes through the VC queues.

Chapter 21 Configuring ATM Connections rt-VBR and nrt-VBR Connections With Rel. 9.2.20 and later,you specify rt-VBR and nrt-VBR connections separately when adding a connection by using the addcon command. To do this, enter either rt-vbr or nrt-vbr to select the rt-VBR or nrt-VBR connection class, respectively. Each connection is assigned the applicable associated default parameters for its type of service. For rt-VBR an additional queue, referred to as the rt-VBR queue, is used at a BXM port.

When using the addcon command without the extended parameters, rt-VBR connections automatically use the parameters provided by connection class 3 which contains pre-determined values. Similarly, nrt-VBR connections use connection class 2.
Chapter 21 Configuring ATM Connections rt-VBR and nrt-VBR Connections Trunk Queues for rt-VBR and nrt-VBR A rt-VBR connection uses the rt-VBR queue on a trunk. It shares this queue with voice traffic. The rt-VBR and voice traffic shares the default or user configured parameters for the rt-VBR queue. These parameters are queue depth, queue CLP high and CLP low thresholds, EFCI threshold, and queue priority. A nrt-VBR connection uses the nrt-VBR queue on a trunk.

Chapter 21 Configuring ATM Connections Traffic Policing Examples Dual-Leaky Bucket (An Analogy) A Generic Cell Rate Algorithm viewpoint is: • For a stream of cells in an ATM connection, the cell compliance is based on the theoretical arrival time (TAT). • The next TAT should be the time of arrival of the last compliant cell plus the expected arrival interval (I) where I = 1/rate. • If the next cell arrives before the new TAT, it must arrive no earlier than new TAT - CDVT to be compliant.

Because SCR=0 for leaky bucket 2, the bucket is essentially always full, and all the CLP(0) cells sent to leaky bucket 2 are therefore tagged with CLP being set to 1. This allows the network to recognize these UBR cells as lower priority cells and available for discard in the event of network congestion.

Chapter 21 Configuring ATM Connections Local Management Interface and Integrated Local Management Interface Parameters It is important to notify the customer premise equipment if a connection is derouted and fails to transport user data after a specified time interval. However, it is also desirable not to send out Abit = 0, then Abit =1 when a connection is derouted and rerouted quickly.

X, is set to be M*N • Abit Timer Multiplier M M can be configured to be from 0 to 100. Default value for M (Abit Timer Multiplier M parameter) is 0, meaning Abit = 0 is sent out on deroute.
Chapter 21 Configuring ATM Connections ATM Command List In releases previous to Release 9.1.07, when connections are derouted, the CPE does not receive Abit notifications. In Release 9.1.07 on BPX, the Send Abit on Deroute feature was developed, which allowed the Abit = 0 to be sent immediately when a connection is derouted. (This was specified by the cnfnodeparm parameter Send Abit immediately parameter.) To further enhance the Send Abit on Deroute feature in Release 9.1.

Chapter 22 Configuring Frame Relay to ATM Network and Service Interworking ATM Protocol Stack Discard selection is based upon the standard CLP bit in the cells. When the routing path enters an IGX switch, a BTM card that supports Interworking traffic is required to convert the connection data from cells to frames (frames to fastpackets out onto MuxBus to FRP/cell bus to FRM), and visa versa. Additionally, the AAL-5 framing is removed upon conversion to frames, and added upon conversion to cells.

Chapter 22 Configuring Frame Relay to ATM Network and Service Interworking Connection Management Bandwidth Management Bandwidth calculations for interworking connections assume a large frame size, which minimizes the loading inefficiency of packets vs. cells. In other words, the translation between packets and cells assumes 100 percent efficiency, so the conversion is simply based on 20 payload bytes per fastpacket versus 48 payload bytes per ATM cell.

C H A P T E R 23 Configuring BXM Virtual Switch Interfaces This chapter describes the BXM Virtual Switch Interfaces (VSIs) and provides configuration procedures: • Virtual Switch Interfaces • VSI Configuration Procedures – Add a controller – View controllers and interfaces – Delete a controller – Enable VSI ILMI functionality – Configure partition resources on VSI • Overview: How VSI Works – VSI Masters and Slaves – Partitioning • VSI Master and Slave Redundancy • Class of Service Templates and Q
Chapter 23 Configuring BXM Virtual Switch Interfaces Virtual Switch Interfaces When a virtual switch interface (VSI) is activated on a port, trunk, or virtual trunk so that it can be used by a master controller, such as a SES PNNI or an MPLS controller, the resources of the virtual interface associated with the port, trunk or virtual trunk are made available to the VSI. These control planes can be external or internal to the switch.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures VSI Configuration Procedures In the VSI control model, a controller sees the switch as a collection of slaves with their interfaces. The controller can establish connections between any two interfaces. The controller uses resources allocated to its partition. You can assign each VSI interface a default class of service template when you activate it.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures Note that addshelf and addtrk are mutually exclusive commands; that is, you can use either addshelf or addtrk, but not both on the same interface shelf. To add a PNNI controller, use the following commands: Step 1 Up a trunk interface by using the uptrk command. Step 2 Configure resource on the trunk interface for the PNNI controller's control channels by using the cnfrsrc command.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures Step 2 Delete the SES attached to the trunk interface by using the delshelf command. Step 3 Disable the VSI resource partition allocated for PNNI controller on the trunk interface by using the cnfrsrc command. Step 4 Down the trunk interface (provided no other VSI partitions are active on the trunk interface) by using the dntrk command.

Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures dspvsiif dspvsiif 1.1 dspvsiif 1.1.1 To change some of the template’s qbin parameters, use the cnfqbin command. The qbin is now “user configured” as opposed to “template configured”. To view this information, use the command dspqbin. SCT Commands dspsct Use the dspsct command to display the service class template number assigned to an interface.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures Once a service template has been assigned, you can then adjust some of the parameters of this configuration on a per-interface basis. Changes you make to the qbin configuration of an interface affect only that interface’s qbin configuration. Your changes do not affect the qbin template assigned to that interface. To change the template’s configuration of the interface, provide new values by using the cnfqbin command.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Configuration Procedures Step 2 Configure the trunk VPI by using the cnftrk command. NOTE: ILMI automatically runs on the BXM card for virtual trunks. This is not configurable by using the cnftrk command. Step 3 Configure a VSI paritition on the virtual trunk interface by using the cnfrsrc command. Step 4 Enable VSI ILMI functionality for the VSI partition by using the cnfvsipart command.

Chapter 23 Configuring BXM Virtual Switch Interfaces Overview: How VSI Works Partitioning The VSIs need to partition the resources between competing controllers, Autoroute, Label Switching, and PNNI for example. You do partitioning by using the cnfrsrc command. Note Release 9.3 supports up to three partitions. For Release. 9.1 and Release 9.2, just one controller (of a particular type) is supported. However, you can have different types of controllers splitting up a partition’s assets.

Chapter 23 Configuring BXM Virtual Switch Interfaces Overview: How VSI Works Compatibility The card uses a flag in the capability message to report multiple partition capability. Firmware releases that do not support multiple partitions set this flag off. The multiple partitions capability is treated as a card attribute and added to the attribute list.

Chapter 23 Configuring BXM Virtual Switch Interfaces Overview: How VSI Works You configure these parameters on a VSI partition on an interface: • min lcn: guaranteed LCNs for the partition on the interface. • max lcn: total number of LCNs the partition is allowed for setting up connections on the interface. • min bw: guaranteed bandwidth for the partition on the interface. • max bw: maximum bandwidth for this partition on the interface.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Master and Slave Redundancy VSI Master and Slave Redundancy The ability to have multiple VSI controllers is referred to as VSI master redundancy. Master redundancy enables multiple VSI masters to control the same partition. You add a redundant controller by using the addshelf command, the same way you add an interface (feeder) shelf, except that you specify a partition that is already in use by another controller.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Master and Slave Redundancy Master Redundancy You add a VSI controller, such as an MPLS or PNNI controller by using the addshelf command with the vsi option. The vsi option of the addshelf command identifies the VSI controllers and distinguishes them from interface shelves (feeders). The VSI controllers are allocated a partition of the switch resources. VSI controllers manage their partition through the VSI interface.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Master and Slave Redundancy VSI Slave Redundancy Mismatch Checking To provide a smooth migration of the VSI feature on the BXM card, line and trunk Y-redundancy is supported. You can pair cards with and without the VSI capability as a Y-redundant pair if the feature is not configured on the given slot.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Master and Slave Redundancy The BCC also informs the slaves of the new controller through a VSI configuration CommBus message (the BPX’s internal messaging protocol). The message includes a list of controllers attached to the switch and their corresponding controller IDs. This internal firmware command includes the interface where the controller is attached.
Chapter 23 Configuring BXM Virtual Switch Interfaces VSI Master and Slave Redundancy How Resources are Managed VSI LCNs are used for setting up the following management channels: • inter-slave • master-slave • intershelf blind channels Intershelf blind channels are used in cluster configuration for communication between slaves on both sides of a trunk between two switches in the same cluster node. The maximum number of slaves in a switch is 12.
Chapter 23 Configuring BXM Virtual Switch Interfaces Class of Service Templates and Qbins 2. VSI messages (from Master VSI controller or other slave VSI card) are forwarded to the standby slave VSI card by the active slave VSI card. Operation 2 is normal data transferring, which occurs after both cards are in-sync. 3. When the standby slave VSI card starts up, it retrieves all VSI messages from the active slave VSI card and processes these messages.
Chapter 23 Configuring BXM Virtual Switch Interfaces Class of Service Templates and Qbins • Autoroute • MPLS Switching When a connection setup request is received from the VSI master in the Label Switch Controller, the VSI slave (in the BXM, for example) uses the service type identifier to index into a Service Class Template database containing extended parameter settings for connections matching that index. The slave uses these values to complete the connection setup and program the hardware.

Table 25-1 Virtual Trunk Criteria BXM Number of VIs Max LCNs Default LCNs 31 32000 16320 This syntax describes a virtual trunk: UXM/BXM:slot.port.vtrunk slot = slot number (1–32) Keep in mind that on the BPX slots 7 and 8 are reserved for BCCs and slot and 15 is reserved for the ASM card.
Chapter 25 Configuring BXM Virtual Trunks How Virtual Trunking Works may have APS line redundancy configured in the same way it would be configured for a physical trunk. The commands addapsln, delapsln, switchapsln, and cnfapsln are all supported on virtual trunk ports. For more information, refer to the Chapter 26, Configuring SONET Automatic Protection System. • Y-redundancy The original trunk redundancy feature is an IGX-only feature and is not used for virtual trunks.

Chapter 25 Configuring BXM Virtual Trunks Connection Management • Integrated Local Management Interface (ILMI) ILMI provides data and control functions for the virtual trunking feature. It is not necessary to configure the ATM ports to block signalling traffic to Cisoc equipment due to ILMI (Integrated Layer Management Interface) signalling support. • Blind Addressing Each virtual trunk is assigned a blind address.
Chapter 25 Configuring BXM Virtual Trunks Connection Management Because the BNI cards use a Strata-UNI format across a virtual trunk, BNI virtual trunks are not compatible with BXM/UXM virtual trunks which use either the standard UNI or NNI cell header formats. Therefore, BXM to BXM, UXM to UXM, and BXM to UXM virtual trunks are supported, while BNI to BXM or BNI to UXM virtual trunks are not supported.
Chapter 25 Configuring BXM Virtual Trunks Connection Management Cell Transmit Address Translation All cells transmitted to a virtual trunk have a translated cell address. This address consists of a VPI chosen by the user and a VCI (ConId) chosen internally by the software. The trunk firmware is configured by the software to perform this translation. Cell Receive Address Lookup The user-chosen VPI is the same for all cells on a virtual trunk.
Chapter 25 Configuring BXM Virtual Trunks Connection Management If the public ATM cloud consists of BPX nodes using BXM cards, the access points within the cloud are BXM ports. If the cloud consists of IGX nodes, the access points within the cloud are UXM ports. Virtual Trunk Interfaces The two ends of a virtual trunk can have different types of port interfaces. For example, a virtual trunk may contain a T3 port at one end of the ATM cloud and an OC-3 port at the other end.
Chapter 25 Configuring BXM Virtual Trunks General Procedure to Set Up a Trunk Virtual Trunk Transmit Queuing In the BXM, the egress cell traffic out a port is queued in 2 stages: • First they are queued per Virtual Interface (VI), each of which supports a virtual trunk. • Within each VI, the traffic is queued as per its normal OptiClass traffic type.
Chapter 25 Configuring BXM Virtual Trunks General Procedure to Set Up a Trunk You cannot use a virtual trunk as an interface shelf (feeder) trunk; similarly, you cannot configure an interface shelf trunk to act as a virtual trunk. Similarly, you cannot terminate interface shelf (feeder) connections on a virtual trunk.
Chapter 25 Configuring BXM Virtual Trunks General Procedure to Set Up a Trunk upport slot.port cnfport slot.port, and set the shift parameter to “N” for no shift. The Shift/No shift parameter specifies whether or not the VCI bits in the cell header should be shifted based on the HCF field of the cell header on cells arriving from the backplane. It is how Cisco networks convert STI cells to standards based cell formats, and similarly how standards-based cell formats are converted back to STI cells.
Chapter 25 Configuring BXM Virtual Trunks General Procedure to Set Up a Trunk • Vtrk is the virtual trunk number, which (for BNIs) can be 1–32 for T3/E3 or 1–11 for OC-3/STM1. Note that the two ends of a virtual trunk can have different port interfaces. For example, a virtual trunk supported by a UXM-OC-3 on one end can be supported by a BXM-T3 at the other end. However, both ends of the trunk must have the same trunk bandwidth, connection channels, cell format, and traffic classes.
Chapter 25 Configuring BXM Virtual Trunks Example: Virtual Trunk Across an ATM Network The CBR/VBR parameter must also correspond to the virtual trunk type of the virtual trunk. For T3, set PCR to 96000 and CDTV to 24000 for the connection so that the BXM does not drop cells. Cisco recommends these values based on testing. Step 5 Configure BXM trunks. Use uptrk to enable the virtual trunk on the port. Take this step if the ATM cloud provider has assigned the VPC.
Chapter 25 Configuring BXM Virtual Trunks Example: Virtual Trunk Across an ATM Network • A virtual trunk is added between port 3 on the BXM and port 2 on the UXM (see Figure 25-6). Given this situation, you would perform these steps: 1. Initial Setup Contact Customer Service to enable virtual trunking on the nodes in your network. 2. In the public ATM cloud Obtain the VPCs for the virtual trunks for the service provider.
Chapter 25 Configuring BXM Virtual Trunks Example: Virtual Trunk Across an ATM Network • traffic classes supported • the number of connection channels supported Use the addtrk command to check for matching values before allowing the trunk to be added to the network topology. The network topology as seen from a dsptrks command at BPX_A would be: BPX_A 4.3.1-10.2.1/IGX_A BPX_A 4.3.2-5.1.

Chapter 25 Configuring BXM Virtual Trunks Command Overview Command Overview The command summarized here are specific to virtual trunk usage on the BPX, using the BXM cards. For complete information about each these commands, refer to the Cisco WAN Switching Command Reference and Cisco WAN Switch SuperUser Command Reference. For information about the UXM, refer to the IGX 8400 Series documents.
Chapter 25 Configuring BXM Virtual Trunks Command Overview This number cannot be greater than the total number of connection channels on the card. The maximum number of channels is additionally limited by the number of VCI bits in the UNI cell header. For a virtual trunk, the number is divided by the maximum number of virtual trunks on the port to determine the default. You configure this value by using the cnfsrc command on the BPX.
Chapter 25 Configuring BXM Virtual Trunks Command Overview With Release 9.2, the BPX statistics organization separates logical and physical trunk statistics. This is also the method used on the UXM card on the IGX 8400 series switches. Virtual Trunks Commands Common to BXM and UXM The following commands are available on both the IGX and the BPX and have the same results. Refer to the IGX 8xxx Series documentation for information the IGX and UXM.

Refer to the IGX 8400 Series documentation for further information about UXM virtual trunk commands.
Chapter 25 Configuring BXM Virtual Trunks Compatibility Between Cards in Virtual Trunks Nodes running Release 9.2 software can interoperate with nodes running 9.1 or 8.5, but you cannot add UXM and BXM virtual trunks into a network of mixed software releases. This is because the networking messages are different among the software releases, specifically the virtual trunk number and the cell format on virtual trunks. You configure the BXM and UXM cards similarly as in releases previous to Release 9.
Chapter 25 Configuring BXM Virtual Trunks Compatibility Between Cards in Virtual Trunks • virtual ports You up and configure virtual trunks with the existing commands. The commands have additional parameters for virtual trunk specific items. You up a trunk with uptrk . You configure the trunk VPI (VPI range 1–4095) and other parameters on the trunk with cnftrk, cnftrkparm, and cnfrsrc commands.

The single backcards and mini-backplane can be ordered as spares.
Chapter 26 Configuring SONET Automatic Protection System APS 1+1 (Card and Line Redundancy) The receiver terminating the APS 1+1 has to select cells from either the working or protection line and be able to forward one consistent traffic stream. Since both working and protection line transport identical information, the receiving ends can switch from one to the other without the need for coordinating with the transmit end.
Chapter 26 Configuring SONET Automatic Protection System APS 1+1 (Card and Line Redundancy) • The APS backcards are inserted into the APS redundant backplane assembly. • The working lines on the backcard must be connected to the same slot as the primary front card • The protection lines connected to the same slot as the secondary front card. The switching of the front cards is controlled by switch software under the Y-redundancy protocol.
Chapter 26 Configuring SONET Automatic Protection System APS 1+1 (Card and Line Redundancy) Note In the APS 1+1 configuration, if the protection line is active and the last user request is “clear,” a switchdred will cause the working line to be active if there is no line condition on working line.

Do not Revert A state request due to the external user request being cleared (such as a forced switch) while using non-revertive switching. 10. No Request A state request due to the external user request being cleared (such as a forced switch) while using revertive switching.
Chapter 29 Troubleshooting Operational Problems APS switch made to a line in alarm Description: You perform a forced switch to a line with a line alarm. The switch is successful making an alarmed line active with possible loss of traffic. Investigation: It is normal operation for a forced switch to cause a switch to a line even though it may be faulty. This enables you to “force” a switch to standby line even if it is in alarm. A traffic outage may occur.
Chapter 29 Troubleshooting Operational Problems Explanation: This is normal operation. An APS clear switch request causes the APS switching mechanism in the BXM to initialize. This will cause a switch back to the working line if the working line is in better shape than the protection line. If the protection line is not faulty, no switch will occur. APS Switch Occurs even though APS Forced switch in effect Description: A forced switch to protection line is performed.
Chapter 29 Troubleshooting Operational Problems APS line does not seem to switch and active line is in alarm Description: A major line alarm is indicated on the active line yet it remains active due to no APS switch to the redundant line. Initial Investigation 1. Verify that the configuration is correct (dspapsln, cnfapsln). See preceding configuration problems. 2. Use dspapsln to check the APS line’s status. The dspapsln display shows the active and standby line’s alarm status.
Chapter 29 Troubleshooting BME Connection Diagnostics BXM Port LED states Scenario: For an APS 1+1 or APS 1:1 line pair, the port LEDS are the same color on working and protection line. Explanation: To switch software, the APS line pair is a single logical line. Although required to send BXM messages to both lines, these messages will be the same message. Thus switch software cannot send different LED states to the BXM for the same APS line.
Chapter 29 Troubleshooting Troubleshooting VSI Problems incremented to keep count of the number of PVCs used. This counter can never exceed the number configured. For the trunk interface, connections will be rerouted if the new value configured is less than the old value. For the port interface, cnfrsrc will not allow you to decrease the configured value to be less than the used value. You will need to delete connections before decreasing the PVC value.
Chapter 29 Troubleshooting Troubleshooting VSI Problems How IP Channels are Allocated IP channels are used for ALL5 messaging. The LCNs are reserved within switch software. The formula for getting the LCN is num_chans + 14 + port (0 based). Twelve (12) LCNs are reserved for IP channels, one for each port. How ILMI/LMI Channels are Allocated The formula for getting the LCN is num_chans + 2 + port.
Chapter 29 Troubleshooting Troubleshooting VSI Problems cnfrsrc fails with “available channels is 0” When the user thinks that there are channels available, but cnfrsrc says that the number of available channels is 0. The user will not be able to allocate any more vsi channels. This might not be a problem because the user might not have accounted for hidden channel assignments like networking and VSI vcs. Execute the dspchuse command to see where all the channels are allocated.
Chapter 29 Troubleshooting Troubleshooting Commands since only five (5) are currently used. The available channels on the card is now 40. If cnfrsrc is executed now to increase the number of VSI channels, the command will fail, because channels 45–49 are currently in use. To check if a specific connection is using a channel out of range: • Verify channel number (LCN) used by the connection by using the command dcct.

C H A P T E R 30 Replacing Parts This chapter describes the replacement of major BPX switch components: • Replacing a Front Card • Replacing a Line Module • Replacing a DC Power Entry Module • Replacing an AC Power Supply • Replacing the Fan Assembly After an alarm occurs, use the BPX switch software to isolate the problem. If an BPX switch part has failed, then it must be replaced. For information on alarms, see Chapter 28, Alarms and Statistics.
Chapter 30 Replacing Parts Replacing a Front Card When a card has failed, the red FAIL indicator for that card turns on. Before replacing it, check to see if the card needs only to be reseated. After reseating the card, wait for it to run its self-tests to see if the ACTIVE light comes on. If the card is seated correctly, but the FAIL light is still on, replace the card. To remove a front cards: Step 1 If the front panel fail lamp is on, remove the card and go to Step 3. Otherwise, go to Step 2.

Chapter 30 Replacing Parts Replacing an AC Power Supply Replacing an AC Power Supply BPX switches are powered by redundant power supplies; either power supply can supply the current requirements of the node. The AC Power Supply is part of an assembly which is replaced as a single unit. Access to the AC Power Supply assembly is from the front, but first, the Air Intake Grille must be removed.
Chapter 30 Replacing Parts Replacing an AC Power Supply Step 8 There are two power supply securing fasteners, one on each side of the power supply assembly (Figure 30-4). The one on the left of each supply is a spring-loaded pin, the one on the right of each supply is a normal thumb-screw. Loosen the thumb-screw on the right. Step 9 With the right hand, grip the power supply under the front panel.
Chapter 30 Replacing Parts Replacing the Fan Assembly Step 4 When the power supply is completely seated, the spring-loaded pin will snap into place to assure that the power supply has mated with its connector. Step 5 Screw in the thumb-screw on the right side of the power supply assembly until it is finger tight. Step 6 Flip the retaining bracket up and tighten its thumbscrew.
Chapter 30 Replacing Parts Replacing the Fan Assembly Step 5 With one hand, pull the Fan Assembly back just far enough to gain access to the Fan Assembly power cord. This cord connects to the Fan Assembly to the backplane. Step 6 Unplug the power cord and remove the Fan Assembly. Step 7 Plug the power cord in the replacement Fan Assembly into the backplane connector. Step 8 Install the replacement Fan Assembly.

P A R T 7 Appendices
A P P E N D I X A Upgrade Information This appendix provides special upgrade information. Upgrade BXM to BXM-E Cards You can now gracefully upgrade your Broadband Switch Module (BXM) card to a BXM-E card without any service interruption (on yred BXMs). The enhanced BXM-E card (version DX or EX) supports a higher connection density (32K) than either the legacy BXM or regular BXM-E cards.
Appendix A Upgrade Information Upgrade Options Table A-1 BXM-BXM-E Upgrade Commands Command Description Default cnfnodeparm Y Configure node parameters, auto BXM upgrade parameter. If set to “Y,” the Switch software upgrades the logical database as soon as both the legacy BXMs are replaced by BXM-Es in yred case, or the active legacy BXM is replaced by a BXM-E in non-yred cases. If set to “N,” you must upgrade the logical database manually using the upgdlogcd command.
Appendix A Upgrade Information Upgrade Options Table A-2 Upgrade Options Option Used when... Yred BXMs, manual Legacy BXMs are yred and the “auto BXM upgrade parameter” is set to “N” for the cnfnodeparm command. Steps 1. Remove the standby BXM card and replace it with the BXM-E card. 2. BXM-E card can be flagged as ‘Mismatch’ if the configured channel statistics level or number of connections is smaller than those configured on the active BXM card.
Appendix A Upgrade Information Upgrade Options Table A-2 Upgrade Options (continued) Option Used when... Stand alone BXM, manual Legacy BXM card is non-yred and the “auto BXM upgrade” parameter is set to “N” for the cnfnodeparm command. Steps 1. Use an empty slot to configure the BXM-E card for the desired level of channel statistics and number of connections.
Appendix A Upgrade Information Upgrade Protection From Release 9.3 to a Later Release Upgrade Protection From Release 9.3 to a Later Release Release 9.3 includes an Upgrade Protection feature. This section provides guidelines on upgrades from BPX switch software Release 9.3 to later releases. Active statistics collection interferes with the software upgrade process. Prior to Release 9.3, you were responsible for turning statistics off before beginning the software upgrade procedure.
Appendix A Upgrade Information Feature Mismatching Feature Mismatching Feature mismatching provides customers a graceful migration path to Release 9.2 features. Switch software Release 9.1 and previous releases of switch software mismatched cards if the capabilities in the logical card database did not match exactly the capabilities of the physical card. This restriction does not allow customers to gracefully migrate their BXM/UXM cards.

OK OK OK OK Single Active Card MM (if VSI Configuration: if the firmware is is downgraded from 9.2 to 9.1, configured) mismatch will occur if the 9.2 feature has been configured.
Appendix A Upgrade Information Feature Mismatching Multiple VSI Partitions Support for up to two partitions requires BPX switch software 9.2.3 and Firmware Ez. The card uses a flag in the capability message to report multiple partition capability. Firmware releases that do not support multiple partitions set this flag to OFF. The multiple partitions capability is treated as a card attribute and added to the attribute list.
Appendix A Upgrade Information Feature Mismatching • During Y-cable mismatch, if the feature is enabled and if the inserted primary or secondary card does not support this feature, the card will mismatch. • During Y-cable mismatch, if the feature is not enabled and if the inserted primary or secondary card does not support the feature, the logical card database will be updated to reflect this.

A P P E N D I X C ATM: An Overview This chapter is an overview of Asynchronous Transfer Mechanism (ATM) on the BPX 8600 Series. ATM transmits broadband information using fixed length, relatively small, 53-byte cells suitable for carrying both constant rate data (such as, voice and video) as well as bursty data. ATM evolved from the Broadband Integrated Services Digital Network (B-ISDN) standard, which in turn is an extension of ISDN.
Appendix C ATM: An Overview • The Physical Medium sub-layer (PMD) This handles processing specific to a particular physical layer, such as transmission rate, clock extractions, and so on. • The Transmission Convergence sub-layer (TC) This extracts the information content from the physical layer data format. This includes HEC generation and checking, extraction of cells from the data stream, processing of idle cells, and so on. ATM Layer The ATM layer processes ATM cells.
