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
•
To configure the connection mode, use the following command:
From the SCE 2000(config if)# prompt, type connection-mode inline-cascade/receive-only-
cascade [physically-connected-links {link-0/link-1}] [priority
{primary/secondary}] [on-failure {bypass/cutoff}] and press Enter.
E 1
XAMPLE
Use the following command to configure the primary SCE platform in a two-SCE platform inline topology. Link 1 is
connected to this SCE platform and the behavior of the SCE platform if a failure occurs is bypass.
SCE 2000(config if)# connection-mode inline-cascade physically-connected-links link-1
priority primary on-failure bypass
