Creating and Binding the SRP Context
Use the example below to create the SRP context and 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. Log onto both chassis before continuing. Always make configuration
changes on the primary chassis first. Before starting this configuration, identify which chassis to configure as the
primary and use that login session.
changes on the primary chassis first. Before starting this configuration, identify which chassis to configure as the
primary and use that login session.
configure
context <srp_ctxt_name> [-noconfirm]
service-redundancy-protocol
bind address <ip_address>
end
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 assigns a chassis mode and priority, and also configures the redundancy link between the primary
and backup chassis:
