Configuring the Service Redundancy Protocol (SRP) Context
To configure the system to work for interchassis session recovery:
Step 1
Create the chassis redundancy context and bind it to primary chassis IP address by applying the example configuration
in the
in the
Step 2
Configure the chassis redundancy context with priority, chassis mode, heart-beat interval, dead-interval and peer IP
address by applying the example configuration in the
address by applying the example configuration in the
Step 3
Configure the SRP context with interface parameters, like interface name, IP address and port number to communicate
with other chassis by applying the example configuration in the
with other chassis by applying the example configuration in the
section.
Step 4
Verify your SRP context configuration by following the steps in the
Step 5
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
Creating and Binding the SRP Context
Use the following example to create the SRP context bind it to primary chassis IP address:
Important:
ICSR is configured using two systems. Be sure to create the redundancy context on both systems.
CLI commands must be executed on both systems. Always make configuration changes on the primary system first. It
would be a good idea to log on both chassis before continuing. Before starting this configuration, determine which
system to configure as the primary and use that login session.

Notes:
ICSR should be configured and maintained in a separate context.
Be sure to bind the local IP address to the primary chassis. When configuring the backup chassis, be sure to bind
the local IP address to the backup chassis.
Configuring the SRP Context Parameters
This configuration assign a chassis mode, priority, and configure the redundancy link between the primary and backup
systems:
