II CHASSIS ADMINISTRATION Chapter 5 Chassis Management Chapter 6 Managing Multiple Chassis Chapter 7 Simple Network Management Protocol (SNMP) Chapter 8 Managing System Events Chapter 9 Module Administration Chapter 10 Packet Over SONET Administration Chapter 11 Fault Management
CHAPTER : ADC Telecommunications, Inc.
5 CHASSIS MANAGEMENT This chapter describes chassis management and chassis configuration functions, and includes the following sections: ■ Understanding Chassis Identification ■ Understanding Management Module Redundancy ■ Configuring a Chassis ■ Configuring Traffic Relay NOTE: You must have access privileges to the Administrator functional area to perform chassis configuration. For more information about access privileges, refer to chapter 3 Managing User Accounts.
CHAPTER 5: CHASSIS MANAGEMENT Understanding Chassis Identification The Cuda 12000 supports the following chassis environment: ■ a multiple-chassis environment, in which multiple chassis are connected through a network environment but do not form a single router. Each Cuda 12000 should be configured with a unique chassis identification (ID) number. The chassis ID serves as a router management tool. ADC Telecommunications, Inc.
Understanding Management Module Redundancy 109 Understanding Management Module Redundancy Each chassis is equipped with at least one management module, which controls the chassis. For management module redundancy, the Cuda 12000 supports installation of two management modules. When two management modules are installed, one acts as the primary management module and the other acts as the secondary management module.
CHAPTER 5: CHASSIS MANAGEMENT When the secondary management module activates its copy of the Cuda 12000 software and establishes connections to cards, the secondary management module also starts services, including disk-mirroring and LDAP. Through disk mirroring, the software on the two management modules share data. When a switch to a secondary management module occurs: ■ Services are unavailable for a brief period of time ■ Network management access is prevented for a brief period of time.
Configuring a Chassis 111 Configuring a Chassis Configuring a chassis consists of these functions: ■ Assigning or changing chassis and cluster IDs. ■ Defining in which slot the Primary module resides. ■ Defining if the Primary module is managing a cluster or independent chassis environment. Figure 5-1 is an example of the Summary window. This window displays chassis identification information for only the primary management module.
CHAPTER 5: CHASSIS MANAGEMENT Table 5-1 Parameter Descriptions of Summary Window Parameter Description Chassis ID Unique identification number you assign to a Cuda 12000 chassis in the network. The Cuda uses a multi-range numbering system. Acceptable chassis ID values are 1 to 128. The Cuda defaults with chassis number 255. We recommend that you do not change the chassis ID.
Configuring a Chassis 113 Perform the following tasks to configure a chassis: Navigation Path GroupName>ChassisName>Cuda Chassis Manager>Configuration Procedure 1. Click the Summary tab. 2. In the Summary window, select the row that includes the chassis or cluster ID that you want to modify. 3. Click the Chassis Designation tab. 4. Enter values for the parameters. 5.

The Cuda 12000 uses a multi-range numbering system. Acceptable chassis ID values are 1 to 128, or 255. The default is one. Primary Controller Slot Read-only.
Configuring a Chassis Parameter 115 Description Slot 13 Select if the management module is in slot 13 and you want it to be the primary controller. Slot 13 is the default. Slot 14 Select if the management module is in slot 14 and you want it to be the primary controller. Controller Module Scope Indicates whether the primary and secondary management modules are managing a chassis or cluster environments. Cluster Manager Select if the management module is controlling a cluster-network environment.
CHAPTER 5: CHASSIS MANAGEMENT Configuring Traffic Relay The traffic relay function configures processes, such as the HTTP server, to send and receive TCP or UDP packets using an internal address on the Cuda 12000, for in-band management. For example, you can enable forwarding of Telnet traffic and HTTP traffic using an internal address, thereby allowing you to perform in-band management of the Cuda 12000 using the CLI or CudaView. To enable or disable traffic relay options, follow these procedures: 1.
Configuring Traffic Relay 117 What You See Figure 5-3 Traffic Relay window. NOTE: If you are running a TFTP server on the Cuda 12000 as part of FastFlow BPM provisioning, you must enable traffic relay for the TFTP server in order to download configuration files to cable modems. The TFTP server sends and receives packets using an internal address. Refer to the FastFlow BPM documentation set for more information on the FastFlow BPM.
CHAPTER 5: CHASSIS MANAGEMENT ADC Telecommunications, Inc.
6 MANAGING MULTIPLE CHASSIS Multi-chassis support allows the network administrator to manage multiple Cuda chassis while logged into the chassis containing the Java applet (the chassis where you have logged in using a GUI login screen). Communication between this chassis and another chassis within the group is by proxy. The GUI on the chassis directly talks to a Java server that can proxy requests to other Java servers for other chassis in the same group and subnet.
CHAPTER 6: MANAGING MULTIPLE CHASSIS You can view multiple chassis in either panel. When you log in to a GUI client, the initial screen (see Figure 6-1, “Initial Multi-Chassis Display”) shows the default group and all chassis in the group that are enabled. Figure 6-1 Initial Multi-Chassis Display If chassis are not already displayed, click on the symbol to the left of the group name in order to expand it into its member chassis.
Managing a Chassis Other Than the GUI Client 121 Managing a Chassis Other Than the GUI Client Selecting a chassis symbol in the left panel by clicking on it performs the following functions: ■ Displays chassis node information in the right panel (Figure 6-2). ■ Expands the directory structure, in the left panel, associated with the chassis folder ( Figure 6-2). ■ Checks your initial login against the user profile on the chassis that is not the GUI client chassis and grants access accordingly.

7 SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP) Simple Network Management Protocol (SNMP) governs the network management and monitoring of network devices and their functions. In addition, SNMP provides secure access to these devices by strategies that can consist of authorizing, authenticating and encrypting SNMP packeting over a network. SNMPv3 includes the SNMPv3 entity. An SNMPv3 entity consists of an SNMP engine and SNMPv application.
CHAPTER 7: SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP) SNMP Security SNMP controls access according to three security models: SNMPv1, SNMPv2c, and SNMPv3. A security level is the permitted level of security within a security model. SNMPv1, SNMPv2c, and SNMPv3 differ in the level of security they provide. SNMPv1 and SNMPv2c perform no authentication that, for example, safeguards against spoofing.

8 MANAGING SYSTEM EVENTS This chapter describe how to manage event transmission and includes the following sections: ■ About System Events ■ Configuring the Event Transmission ■ Configuring Event Reporting ■ Event Levels and SNMP Notification Types ■ Viewing the Events ■ Clearing the Event Log
CHAPTER 8: MANAGING SYSTEM EVENTS About System Events An event is a problem, a configuration change or some other noteworthy incident that occurs on the Cuda 12000 or in the network. Events create the generation of: ■ System log (syslog) messages ■ SNMP traps, which the Cuda 12000 sends to network management stations (configured as SNMP Hosts) ■ Internal log messages Before You Begin Before you configure system events, follow this procedure: 1.
Configuring the Event Transmission 181 Configuring the Event Transmission A Cuda 12000 can generate a significant volume of events in a short period of time. The Cuda 12000 manages event transmission in compliance with DOCSIS 1.1 standards. To avoid flooding the syslog server and network management stations with events, you can control the pace of event transmission by configuring the following parameters: Parameter Descriptions This table provides a description of the Event Configuration window.
CHAPTER 8: MANAGING SYSTEM EVENTS Parameter Description Throttle Threshold Read only. Number of events that the Cuda 12000 may generate per event interval before throttling occurs. Throttling is the process of eliminating excessive events. Note that an event causing both a trap and a syslog message is still treated as a single event. Values range from 0 to 4294967295. The default is 0. Throttle Interval Read only. The interval, in seconds, over which the event (Seconds) threshold applies.
Configuring Event Reporting 183 Configuring Event Reporting Each Cuda 12000 event belongs to one of eight event levels. An event level defines the severity of the event.

13 CREATING ROUTE FILTERS This chapter provides information and procedures on how to configure RIP and OSPF Route Filters.
CHAPTER 13: CREATING ROUTE FILTERS Import and Export Route Filtering for RIP and OSPF The Cuda 12000 uses route filtering functions to control the flow of routes to and from other RIP and OSPF routers. Two filtering functions are supported for control of RIP and OSPF routes; they are: import and export. ■ Import — Controls how routes are added to the Cuda 12000 routing table. ■ Export — Controls which routes are advertised to other routers.

CHAPTER 14: IP PACKET FILTERING About IP Packet Filtering The Cuda 12000 supports packet filtering in the form of access lists. Access lists allow you to restrict and control IP packet flow over specified cable interfaces. This control of IP packet transmission restricts network access from specified users, devices, and applications. IP packet filtering involves: ■ Creating access lists to define the IP packet filtering criteria. ■ Applying the access lists to specified interfaces.
About IP Packet Filtering What You See Figure 14-1 IP Packet Filter Interface Summary Window Cuda 12000 IP Access Switch CudaView Administration Guide 397
CHAPTER 14: IP PACKET FILTERING Access Lists Access lists are sequential groupings of permit and deny rules. These rules enable you to permit or deny packets from crossing specified interfaces. An access list is comprised of rules containing both match criteria and actions to take upon finding a match.
Access Lists 399 Figure 14-2 shows a logical representation of an access list: Figure 14-2 Access List Access List Rule 1 match / action Rule 2 match / action Rule 3 match / action Rule 2 match / action Implicit Deny You can use access lists to filter these protocols: ■ Internet Protocol (IP) ■ Transmission Control Protocol (TCP) ■ User Datagram Protocol (UDP) When masking network addresses, 0 indicates “care” bits; 1 indicates “don’t care.” For example, a class C network would be masked as 0.0.0.
CHAPTER 14: IP PACKET FILTERING What You See Figure 14-3 Filtering Rules Summary Window Creating Access Lists To create access lists, follow this procedure: 1. In the Filtering Rules window, click the Configuration tab. The Configuration window appears. 2. Enter values for the parameters. Refer to Table 14-1. 3.

CHAPTER 14: IP PACKET FILTERING Applying Access Lists to Interfaces After you create an access list, you can apply it to one or more CMTS interface to filter traffic. Filters can be applied to either outbound or inbound interfaces or both. Filtering is enabled automatically when you apply an access list to an interface. When filtering is enabled with no access lists applied to the interface, the interface permits all traffic to pass.
Applying Access Lists to Interfaces What You See Figure 14-5 Access Classes Window Parameter Descriptions This table provides a description of the Access Classes window Table 14-2 Access Classes Parameters. Parameter Description Access Lists List Number Index number that identifies the list Number of Rules Number of rules in a list Incoming Access Classes Access List Index number that identifies the list.

Navigate to Network Browser > GroupName > ChassisName > Cuda Chassis Manager > Configuration > IP > IP Packet Filtering. 2.
CHAPTER 14: IP PACKET FILTERING Table 14-3 Filter Aging Summary Parameters Parameter Description Chassis ID Unique identification number you assign to a Cuda 12000 chassis in the network. The Cuda uses a multi-range numbering system. Acceptable chassis ID values are 1 to 128. The Cuda defaults with chassis number 255. We recommend that you do not change the chassis ID.
Enabling or Disabling IP Filter Aging 411 Parameter Descriptions This table provides a description of the Filter Aging Configuration window Table 14-4 Filter Aging Configuration Parameters. Parameter Description Filter Age In Select or deselect the Filter Age In check box to enable or disable IP Filter Age In Filter Age In Rate Filter Age Out Filter Age Out Rate Indicates the flow aging rate, in flows/second, when Flow Age In is enabled. The valid range is 400 - 4096 flows/second.
CHAPTER 14: IP PACKET FILTERING Packet Filtering Considerations When creating packet filters, consider these points: ■ Access lists contain an implicit deny at the end. This means packets for which no match is found are rejected. When more than one access list is applied to an interface, non-matching packets are compared to the access-list with the next highest priority. If a match is still not found, the packet is matched against the next access list.
15 NETWORK-LAYER BRIDGING Network-layer bridging allows a single subnet to span across multiple DOCSIS modules.
CHAPTER 15: NETWORK-LAYER BRIDGING About Network-Layer Bridging Network-layer bridging allows you to add the same IP address to multiple physical interfaces throughout the system. Of particular value is the ability to propagate the same IP gateway across cable interfaces on multiple DOCSIS (CMTS) modules. The cable modem, customer premise equipment (CPE), or Multimedia Terminal Adapter (MTA) gateway determines the subnet to which a modem, CPE, or MTA can belong.
Creating Network-Layer Bridges 415 Creating Network-Layer Bridges The key to spanning a single subnet across multiple DOCSIS modules is to configure the same IP gateway on each module. The gateway serves as the key that dictates address assignment for cable modems and CPE devices, as a result, configuring the same IP gateway on each cable interface enables the DHCP server to assign those devices IP addresses from the same subnet or subnet pool.
CHAPTER 15: NETWORK-LAYER BRIDGING The system supports network-layer bridging within a single chassis where egress ports within the chassis share an IP address. It also supports network-layer bridging within a cluster where egress ports on modules that reside in different chassis can share an IP address. In this way, the layer 3 bridge can span across a single chassis, or multiple chassis in the same cluster.
Creating Network-Layer Bridges 417 Table 15-1 Summary Window Parameters Parameter Description Name The name of this network layer bridge group. Chassis Specifies the chassis ID of the NLBG group in the network. The Cuda 12000 assigns chassis number 129 to all NLBG groups. Slot Specifies the slot for the NLBG group.

CHAPTER 16: CONFIGURING DHCP RELAY Configuring DHCP Authority DHCP authority is a security feature that prevents spoofing (unauthorized use) of DHCP assigned IP addresses. Spoofing occurs when a host uses an IP address that was dynamically assigned to another host via DHCP. DHCP Authority prevents spoofing of IP addresses by ensuring that IP addresses are only used by the specific cable modems and the CPE devices to which they are assigned.
Configuring DHCP Authority ■ 443 If there is no DHCP Authority range, the entry is simply added to the ARP cache and labelled as type “Dynamic” when the ARP mapping is learned. This feature is termed DHCP Authority because those tagged as being assigned via DHCP take precedence over dynamically assigned (non-DHCP tagged) ARP entries. Enabling and Disabling DHCP Authority To enable or disable DHCP authority on an interface, follow this procedure: 1.
CHAPTER 16: CONFIGURING DHCP RELAY What You See Figure 16-4 DHCP Authority window. Configuring DHCP Authority Ranges The DHCP Authority ranges that you define for an interface dictate what addresses are protected by the authority feature. The DHCP Authority IP address ranges that you define must fall within the range of IP addresses as allowed by the IP interface (as dictated by the network mask for that IP interface). For example, if the physical interface has an IP interface of 172.16.19.

ADC Telecommunications, Inc.
DHCP and BOOTP Policies 447 DHCP and BOOTP Policies You can use Dynamic Host Configuration Protocol (DHCP) policies to control which devices obtain IP addresses and which servers allocate those addresses. A DOCSIS-compliant network uses DHCP for dynamic assignment of IP addresses. A DHCP server allocates addresses and other IP operational parameters to requesting cable modems and CPE devices.
CHAPTER 16: CONFIGURING DHCP RELAY If there are no policies defined, or a DHCP packet does not match any existing policy, the default policy is used to determine if the packet is dropped or forwarded to a list of up to three DHCP servers. The system ships with a default policy to deny (drop) DHCP requests that do not match any other policy. Note that while other DHCP policies are interface-specific, the default DHCP policy is module-wide—it provides default behavior for all interfaces on the module.
Configuring DHCP Policies 449 Configuring DHCP Policies DHCP policies determine the DHCP servers to which a CMTS interface forwards DHCP requests from attached cable modems and CPE devices. 1. Navigate to Network Browser > GroupName > ChassisName > Cuda Chassis Manager > Configuration > IP > DHCP. 2. Click the Summary tab. 3.

A CONFIGURING EXTERNAL PROVISIONING SERVERS A DHCP server is required for cable modems, MTAs, and CPE devices to boot and receive their IP configuration information — such as IP address and host options. DHCP servers fall into two categories: ■ External — DHCP servers that reside on systems other than your local Cuda 12000 (that is, the Cuda 12000 that has the cable interface that you are configuring). DHCP messages are forwarded over the network to a remote, external DHCP server.
APPENDIX A: CONFIGURING EXTERNAL PROVISIONING SERVERS If you are not using the internal FastFlow BPM DHCP server and are instead using an external DHCP server, then you must point the DHCP relay agent on the CMTS DOCSIS/EuroDOCSIS module to the IP address of the external provisioning server. The following procedure steps you through the process of configuring the CMTS to use an external DHCP provisioning server.
4. Choose Add to open the Add DHCP Server Host box. Figure A - 1 Add DHCP Server Host Box Display 5. Enter the DHCP Server IP address to be used for the external provisioning server, on the selected interface. 6. Click OK to save the setting; or click Cancel to exit “Add DHCP Server Host,” without saving the configuration.
