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

Topology-Related Parameters for Redundant Topologies

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

How to Configure the Connection Mode

Use the following command to configure the connection mode, including the following parameters:
•
•
•
•
From the SCE(config if)# prompt, type connection-mode inline-cascade sce-id (0 | 1) priority
Step 1
(primary|secondary) on-failure (external-bypass|bypass|cutoff) and press Enter.

Connection mode — Redundancy is achieved by cascading two SCE platforms. Therefore the
connection mode for both SCE platforms is:
Inline-cascade
–
sce-id — For each of the cascaded SCE platforms, this parameter specifies the SCE platform (0 or
1) to be configured by the command.
The sce-id parameter, which identifies the SCE platform, replaces the physically-connected-link
parameter, which identified the link. This change was required since the SCE8000 GBE platform
supports multiple links. However, for backwards compatibility, the physically-connected-link
parameter will still be recognized and the number of the link assigned to that parameter (0 or 1)
will be defined as the sce-id.
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 via an external optical bypass module when the SCE platform
either has failed or is booting.
If either the bypass or external-bypass option is configured, the optical bypass module must be
properly installed. If an optical bypass device is not detected, the command is executed but a
warning is issued. The system then enters warning mode until either the command is changed, or the
presence of an optical bypass device is detected
