Configuring Route Processor Redundancy (Catalyst 8540 MSR)

For redundant operation, the following requirements must be met:
•
•
•
•
•
If these requirements are met, the Catalyst 8540 MSR runs in redundant mode by default. The tasks
described in the following sections are optional and used only to change nondefault values.

Forcing a Route Processor Switchover (Catalyst 8540 MSR)

You can manually force the secondary route processor to take over as the primary using the
force-failover main-cpu (Catalyst 8540 MSR)
When you use the
Note
key pair is automatically generated on the new primary route processor. For more information, see
Chapter 4, "Configuring Secure Shell."
OL-7396-01
Connection Preservation During Route Processor Switchover (continued)
Two route processors and three switch cards are required.
The route processors must have identical hardware configurations. This includes variables such as
DRAM size, presence or absence of network clock modules, and so on.
Both route processors must have the same functional image. For more information, see
"Managing Configuration Files, System Images, and Functional Images."
Both route processors must be running the same system image.
Both route processors must be set to autoboot (a default setting).
