Configuring the SRP Context Parameters
This configuration assigns a chassis mode and priority, and also configures the redundancy link between the primary
and backup chassis:
and backup chassis:
Important:
CLI commands must be executed on both chassis. Log onto both chassis before continuing. Always
make configuration changes on the primary chassis first.

context srp_ctxt_name

priority priority

end
Notes:
ICSR should be configured and maintained in a separate context.
When assigning the chassis mode on the backup chassis be sure to enter the backup keyword.
The priority determines which chassis becomes active in the event that both chassis are misconfigured with the
assign different priorities to each chassis.
Enter the IP chassis of the backup chassis as the peer-ip-address to the primary chassis. Assign the IP address of
the primary chassis as the peer-ip-address to the backup chassis.
The dead-interval must be at least three times greater than the hello-interval. For example, if the hello interval
is 10, the dead interval should be at least 30. System performance is severely impacted if the hello interval and
dead interval are not set properly.
