Synchronizing the Primary and Secondary CMMs

If you have a secondary CMM in your switch, it will be necessary to synchronize the software between the

primary and secondary CMMs. If the primary CMM goes down then the switch fails over to the second-

ary CMM. If the software in the secondary CMM is not synchronized with the software in the primary

CMM, the switch will not function as configured by the administrator.

At the same time that you copy the RUNNING DIRECTORY to the certified directory, you can synchro-

nize the secondary CMM with the primary CMM. To copy the RUNNING DIRECTORY to the certified

directory of the primary CMM and at the same time synchronize the software of the primary and second-

ary CMM, use the following command:

-> copy running certified flash-synchro

The synchronization process is shown in the diagram below:

In the above diagram:

1 The primary CMM copies its RUNNING-CONFIGURATION to the certified directory.

2 Since the RUNNING-CONIFIGURATION is always synchronzied between redundant CMMs, the

secondary CMM copies its RUNNING-CONIFIGURATION to the certified directory.

To just synchronize the secondary CMM to the primary CMM, enter the following command at the

prompt:

-> copy flash-synchro

The copy flash-synchro command is described in detail in the OmniSwitch AOS Release 7 CLI Reference

Guide.
