Cisco Systems SCE 2000 4/8xFE CLI Commands for Cascaded Systems, Configuring the Connection Mode

Chapter 6 Cabling the Line Ports and Completing the Installation

Installing a Cascaded System

Step 9 Connect the traffic port of SCE 2000 #2, this will cause a momentary down time until the network elements from both sides of the SCE 2000 auto-negotiate with it and starts working (when working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-4).)

Step 10 When full control is needed, change the link mode on both SCE 2000s on both links to ‘forwarding’. It is recommended to first configure the active SCE 2000 and then the standby. (See Link Mode (on page 6-11).)

Step 11 You can now start working with the Subscriber Manager.

CLI Commands for Cascaded Systems

This section presents CLI commands relevant to the configuration and monitoring of a redundant system.

Use the following commands to configure and monitor a redundant system:

•connection-mode

•[no] force failure-condition

•Show interface linecard 'number' connection-mode

•Show interface linecard 'number' physically-connected links

Topology-Related Parameters for Redundant Topologies

All four of the topology-related parameters are required when configuring a redundant topology.

•Connection mode — Redundancy is achieved by cascading two SCE platforms. Therefore the connection mode for both SCE platforms may be either:

•Inline-cascade

•Receive-only-cascade

•Physically-connected-links— For each of the cascaded SCE platforms, this parameter defines the number of the link (Link 0 or Link 1) connected to this SCE platform.

•Priority — For each of the cascaded SCE platforms, this parameter defines whether it is the primary or secondary device.

•On-failure— For each of the cascaded SCE platforms, this parameter determines whether the system cuts the traffic or bypasses it when the SCE platform either has failed or is booting.

Configuring the Connection Mode

Use the following command to configure the connection mode, including the following parameters:

•inline/receive only

•physically connected links

•behavior upon failure of the SCE platform

•primary/secondary
