Scenario 3: Synchronizing Switches in a Stack
When changes have been made to the primary CMM switch certified directory, they need to be propa-
gated 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
copy flash-synchro command can be issued.
The following diagram illustrates the process that occurs when using a copy flash-synchro command. The
stack shown is a three switch stack.
Synchronizing Switches in a Stack
The copy flash-synchro command (described in “Synchronizing the Primary and Secondary CMMs” on
page 4-26 ) can be issued on its own, or in conjunction with the copy working certified command
(described in “Copying the Working Directory to the Certified Directory” on page 4-25 ).
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
“Copying the Working Directory to the Certified Directory” on
page 4-20 , while synchronizing the switch is described in “Synchronizing the Primary and Secondary
CMMs” on page 4-26 .

1. A copy flash-
synchro com-
mand is issued on
the primary CMM
switch.
2. The contents of
the certified direc-
tory of the primary
CMM switch are
copied to the
working directory
of the secondary
CMM switch. The
working directory
is then copied to
the certified direc-
tory.
3. The contents of
the certified direc-
tory of the pri-
mary CMM switch
are copied to the
working directory
of additional
switches. The
working directory
is then copied to
the certified direc-
tory.
