Synchronizing the Primary and Secondary CMMs
CMM synchronization refers to the process of copying all files in the
/flash/working
and
/flash/certified
directories of the primary CMM to the
/flash/working
and
/flash/certified
directories of the secondary
CMM. This ensures that the these directories match exactly on both modules, which prevents the second-
ary CMM from assuming the primary role with incorrect or outdated software or configuration files in the
event of a primary CMM failure.
Important.
In order to have effective CMM redundancy, CMM modules must be synchronized at all
times.
To synchronize the primary and secondary CMM modules, enter the following command at the CLI
prompt:
-> copy flash-synchro
For more information on CMM synchronization and managing the
/flash/working
and
/flash/certified
directories, refer to the “Managing CMM Directory Content” chapter in the
Switch Management Guide
