Managing CMM Directory Content
Scenario 3: Synchronizing Switches in a Stack
When changes have been made to the primary CMM switch certified directory, these changes need to be
propagated to the other switches in the stack. This could be done by completely rebooting the stack.
However, a loss of switch functionality is to be avoided, a
The following diagram illustrates the process that occurs when using a copy flash-synchro command. The
stack shown is a three switch stack.

The copy flash-synchro command (described in

Note. It is important to certify the working directory and synchronize the stack as soon as the validity of
the software is established. Stacks booted from the working directory or unsynchronized stacks are at risk
of mismanaging data traffic due to incompatibilities in different versions of switch software. Certifying
the working directory is described in
page 5-20, while synchronizing the switch is described in
