Chapter5 Configuring Redundancy
Synchronizing the Dynamic Information (Catalyst 8540 MSR)
Example
In the following example, both the running configuration and dyna mic 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 t he 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.
Step5 Switch(config-r-mc)# end
Switch#
Returns to privileged EXEC mode.
Step6 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
Step1 Switch(config)# redundancy
Switch(config-r)#
Enters redundancy configuration mode.
Step2 Switch(config-r)# main-cpu
Switch(config-r-mc)#
Enters main CPU configuration submode.
Step3 Switch(config-r-mc)# sync counters vc minutes Enables periodic synchronization of the VC
counters between the route processors.
Step4 Switch(config-r-mc)# sync counters interface
minutes
Enables periodic synchronization of the VC
counters between the route processors.
Step5 Switch(config-r-mc)# sync counters signaling Enables synchronization of signaling events
between the route processors.
Step6 Switch(config-r-mc)# end
Switch#
Returns to privileged EXEC mode.
Step7 Switch# copy system:running-config
nvram:startup-config
Copies the configuration to NVRAM.
