Chapter 5 Configuring Redundancy
Synchronizing the Dynamic Information (Catalyst 8540 MSR)
Example
In the following example, both the running configuration and dynamic information are synchronized:
Switch(config)# redundancy
Switch(config-r)# main-cpu
Switch(config-r-mc)# sync config running
Switch(config-r-mc)# sync dynamic-info
Switch(config-r-mc)# end
Switch# copy system:running-config nvram:startup-config
Configuring Counter Synchronization (Catalyst 8540 MSR)
To configure synchronizing of the VC, interface, and signaling counters between the primary and
secondary route processors, perform the following steps on the primary route processor, beginning in
global configuration mode:
Note The counters of the primary and secondary route processors might not match exactly
because the counters are only updated periodically. The difference depends on the
frequency of the updates.
Step 5
Switch(config-r-mc)# end
Switch#
Returns to privileged EXEC mode.
Step 6
Switch# copy system:running-config
nvram:startup-config
Copies the configuration to NVRAM.
1. The sync-dynamic info command is enabled by default.
Command Purpose
Command Purpose
Step 1
Switch(config)# redundancy
Switch(config-r)#
Enters redundancy configuration mode.
Step 2
Switch(config-r)# main-cpu
Switch(config-r-mc)#
Enters main CPU configuration submode.
Step 3
Switch(config-r-mc)# sync counters vc minutes Enables periodic synchronization of the VC
counters between the route processors.
Step 4
Switch(config-r-mc)# sync counters interface
minutes
Enables periodic synchronization of the VC
counters between the route processors.
Step 5
Switch(config-r-mc)# sync counters signaling Enables synchronization of signaling events
between the route processors.
Step 6
Switch(config-r-mc)# end
Switch#
Returns to privileged EXEC mode.
Step 7
Switch# copy system:running-config
nvram:startup-config
Copies the configuration to NVRAM.
