Configuring Srp Context Parameters; Basic Parameters - Cisco ASR 5500 Administration Manual

Configuring the Service Redundancy Protocol (SRP) Context
ICSR is configured on two systems. Be sure to create the redundancy context on both systems. CLI
Important
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.
configure
context srp_ctxt_name
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 SRP Context Parameters

Important CLI commands must be executed on both chassis. Log onto both chassis before continuing. Always make
configuration changes on the primary chassis first.

Basic Parameters

This configuration assigns a chassis mode and priority, and also configures the redundancy link between the
primary and backup chassis:
configure
context srp_ctxt_name
service-redundancy-protocol
chassis-mode
priority priority
peer-ip-address ip_address
hello-interval dur_sec
dead-interval dead_dur_sec
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 checkpoint command sets the amount of time the chassis waits before check pointing an existing
call session. Checkpoints can be set for IMS (VoLTE) and/or non-IMS sessions. The checkpoint is a
snapshot of the current application state that can be used to restart its execution in case of failure. The
default setting is 60 seconds.
