C H A P T E R 2 Cisco IGX 8400 Series Cards This chapter provides a description of the cards available for use in the IGX node. Some of the cards described in this manual may no longer be available for purchase, so please check with your account representative for card availability. Most cards use the standard installation and initial configuration procedures described in “Installing the IGX” This chapter details exceptions and recommendations specific to each card.
PAGE 32
Chapter 2 Cisco IGX 8400 Series Cards Nodal Processor Module Nodal Processor Module The IGX nodal processor module (NPM) group consists of a front card (called NPM) and a system clock module (SCM) back card. The NPM performs the following major functions: • Runs the software for controlling, configuring, diagnosing, and monitoring the IGX switch. • Sends configuration and control commands over the control bus to other cards in the switch.
PAGE 33
Chapter 2 Cisco IGX 8400 Series Cards Nodal Processor Module NPM Front Card The NPM front card monitors its own activity. When a failure is detected, the fail LED is lit. In nodes with redundant NPMs, the active NPM is indicated by an active LED, while the standby NPM will not have a lit active LED (see Figure 2-2). To display information on any NPM from the switch software command-line interface (CLI), use the switch software dspcd command.
PAGE 34
Chapter 2 Cisco IGX 8400 Series Cards Nodal Processor Module NPM Failovers and Card Redundancy In a nonredundant system, the NPM front card resides in either slot 1 or slot 2 (see the “Disabling NPM Redundancy” section on page 2-4 for information on disabling NPM redundancy). In a redundant system with two NPM front cards, the front cards reside in slot 1 and slot 2. A utility bus in the backplane connects redundant NPMs.

Chapter 2 Cisco IGX 8400 Series Cards Nodal Processor Module Each operating IGX node must have an SCM. Removal of the SCM disrupts system operation. The SCM resides in back card slot 1 (for information on installing back cards, see the Installing the IGX chapter in the Cisco IGX 8400 Series Installation Guide). Tip One SCM is sufficient to support redundant NPM front cards.
PAGE 38
Chapter 2 Cisco IGX 8400 Series Cards Alarm Relay Module Note If a firmware image upgrade is necessary for a card installed in the node, you may need to upgrade the card’s firmware before upgrading the switch software image to avoid operational problems in your network. Check the firmware release notes for specific information on upgrade procedures. Optional Peripherals At least one node in a network should have a Cisco WAN Manager terminal, a control terminal, or a dial-in modem connected to it.

PAGE 43
Chapter 2 Cisco IGX 8400 Series Cards Alarm Relay Module Caution To avoid disruption of necessary network traffic, do not generate a major alarm during periods of high network traffic. Step 5 Check that the major LED lights up on the front card faceplate of the ARM. Step 6 Using a voltage/ohm meter (VOM), make sure continuity exists between pins 16 and 17 and between pins 35 and 36 at the DB-37 connector on the ARI card.
PAGE 44
Chapter 2 Cisco IGX 8400 Series Cards Service Modules Card Self-Test Diagnostic routines periodically run to test the card's performance. These diagnostics run in the background and do not disrupt normal behavior. If a failure is detected during the self-test, the faceplate red fail LED turns on. In addition, you can check the status of the card by using the switch software dspcd command. If a card failure is reported, the report remains until cleared.
PAGE 45
Chapter 2 Cisco IGX 8400 Series Cards Service Modules Standard Service Module Installation Caution In order to contain electromagnetic interference (EMI) and radio frequency interference (RFI), and to ensure desired airflow for adequate chassis cooling, install a blank faceplate in any back card slots where no back card exists. Except where noted, IGX service modules use a standard installation procedure (see Chapter 3, “Installing the IGX” in the Cisco IGX 8400 Series Installation Guide).
PAGE 46
Chapter 2 Cisco IGX 8400 Series Cards Network Trunk Module Standard Service Module Troubleshooting The following paragraphs describe standard service module maintenance and troubleshooting features. Except where noted, preventive maintenance is not necessary. Card Mismatch When you connect an unsupported back card to the service module front card, the output from the switch software dspcds command informs you that you have a card mismatch.
PAGE 47
Chapter 2 Cisco IGX 8400 Series Cards Network Trunk Module NTM Front Card Note There are two variants of the NTM front card: one uses an ACM1 adapter to connect two legacy card designs and the other is a single card version built for the IGX chassis. While functionally identical, their firmware cannot be interchanged. The single-card NTM requires firmware revision F or later. An NTM front card can occupy any available front service card slot (slots 3 to 32).

Chapter 2 Cisco IGX 8400 Series Cards Universal Switching Module UXM-E Redundancy Like other IGX service modules, the UXM-E can be configured for Y-cable redundancy. Both cards, the primary and the redundant, must be installed before you configure them for Y-cable redundancy. The UXM-E features hot standby, in which the redundant card receives card configuration information as soon as you finish specifying redundancy.
PAGE 64
Chapter 2 Cisco IGX 8400 Series Cards Universal Switching Module Y-Redundancy and VC Merge on the UXM-E Note Because VC merge is not supported on the UXM, y-redundancy cannot be set up using a UXM-E and a UXM without generating a feature mismatch error. If y-redundancy is set up between a UXM-E and a UXM, the VC merge feature cannot be enabled. Before setting up y-redundancy on two UXM-E cards, make sure that VC merge feature support is enabled on both cards.

Chapter 2 Cisco IGX 8400 Series Cards Universal Frame Module Note Actual data throughput on the card depends on hardware and on frame size. As the frame size decreases, throughput will decrease. For example, a frame size of 100 B results in a sustainable throughput of 16.384 Mbps. With 60 B frames, a throughput of 16.384 Mbps can result in data loss. Tip UFM-8C front cards are simply labeled “UFM-C” while UFM-4C front cards are labeled “UFM-4C.

Chapter 2 Cisco IGX 8400 Series Cards Universal Frame Module UFM-U Configuration Because of hardware constraints, the UFM-U does not permit random combinations of speeds across active ports. Configuring active ports on the UFM-U requires that you use certain specified combinations (called modes) of maximum rates on these active ports. Note Specifying the maximum speed for active ports requires careful planning, so read the following information before attempting to configure your UFM-U active ports.

C H A P T E R 3 Cisco IGX 8400 Series Nodes In an IGX-only network, IGX nodes function as both network backbones and network access points. In a mixed network, an IGX node can perform a variety of functions, including traffic routing and bandwidth optimization, network administration and synchronization, and job management. For information about the BPX, see Chapter 1, “The BPX Switch: Functional Overview,” in the Cisco BPX 8600 Series Installation and Configuration guide.
PAGE 148
Chapter 3 Cisco IGX 8400 Series Nodes Functional Overview Whenever a clock source changes (because of a line repair or an operator’s command, for example) the node ensures that the clock path remains hierarchical. Also, whenever a subnetwork is merged with another subnetwork, each node in the new network verifies that it has the nearest, most stable clock that is available. A continuous clock test compares the frequency of the node clock source to a reference on the control card.

Chapter 3 Cisco IGX 8400 Series Nodes IGX Network Management For an example of how this feature works, refer to Figure 3-5. If a trunk is established between switches A and B with a bandwidth of 1000 load units, it can support connection 1 (Conn. 1) with a bandwidth of 800. However, if we add a second connection (Conn. 2) with a bandwidth of 500, the trunk can no longer support both connections.
PAGE 158
Chapter 3 Cisco IGX 8400 Series Nodes IGX Network Management All traffic on the connections is uninterrupted, but if Trunk AB fails, Trunk BC, with a bandwidth of 600, cannot handle the total bandwidth of both connections (700). Connection 1 is in Band 5; connection 2 is in Band 7. The lower the band, the higher the priority. Connection 2 is bumped to accommodate connection 1 with the higher priority.

Chapter 10 Cisco IGX 8400 Series IP Service IP Service—Functional Overview MPLS-enabled IP VPN networks provide the foundation for delivering value-added IP services, such as multimedia application support, packet voice, and application hosting, all of which require specific service quality and privacy. Because QoS and privacy are an integral part of MPLS, they no longer require separate network engineering.
PAGE 246
Chapter 10 Cisco IGX 8400 Series IP Service IP Service—Functional Overview QoS addresses two fundamental requirements for applications that run on a VPN: predictable performance and policy implementation. Policies are used to assign resources to applications, project groups, or servers in a prioritized way.
PAGE 247
Chapter 10 Cisco IGX 8400 Series IP Service IP Service—Functional Overview Without MPLS, IP transport over ATM networks require a complex hierarchy of translation protocols to map IP addressing and routing into ATM addressing and routing. MPLS eliminates complexity by mapping IP addressing and routing information directly into ATM switching tables. The MPLS label-swapping paradigm is the same mechanism that ATM switches use to forward ATM cells.
PAGE 248
Chapter 10 Cisco IGX 8400 Series IP Service IP Service—Functional Overview Additional security is assured because all traffic is forwarded using LSPs, which define a specific path through the network that cannot be altered. This label-based paradigm is the same property that assures privacy in Frame Relay and ATM connections.

Chapter 10 Cisco IGX 8400 Series IP Service IP Service Provisioning In a Y-redundancy pair configuration, the VSI capability is determined by the minimum of the two cards. A card without VSI capabilities will mismatch if any of the interfaces has an active partition on controller. Attempts to enable a partition or add a controller on a logical card that does not support VSI are blocked. Adding and Deleting Controllers and Slaves You add an LSC to a node by using the addctrlr command.

Chapter 10 Cisco IGX 8400 Series IP Service IP Service Provisioning Figure 10-18 shows the MPLS label swapping process. This process might take place during the transportation of the IP packets, in the form of ATM cells across the network on the LVC1 and LVC2 virtual circuits: 1. An unlabeled IP packet with destination 204.133.44.129 arrives at edge label switching router (LSR-A). 2. Edge LSR-A checks its label forwarding information base (LFIB) and matches the destination with prefix 204.133.44.0/8.

A P P E N D I X A Cisco IGX 8400 Series Feeder Nodes About Tiered Networks Tiered networks were introduced in Cisco WAN Switching Software Release 8.0 as an alternative approach to building large networks. In a tiered network, you construct high-capacity node clusters at primary points of presence (POPs) and place smaller capacity nodes at secondary and tertiary POPs. Each node in a tiered network is identified as either a routing node or a feeder node.
