Synchronizing Switches in a Stack
“CMM” synchronization refers to the process of copying all files in the /flash/working and /flash/ certified directories of the switch with the primary Chassis Management Module (CMM) role to the /flash/working and /flash/certified directories of all the other switches in the stack. (This includes the switch with the secondary CMM role and all the switches with an idle CMM role.)
This synchronization process ensures that these directories match exactly for all switches in the stack. Synchronization prevents any switch in the stack from assuming the primary role with incorrect or outdated software or configuration files.
Important. In order to have effective redundancy, switches in the stack must be synchronized at all times.
To synchronize the switches in the stack, enter the following command at the CLI prompt:
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 OmniSwitch 6624/6648 Switch Management Guide.
Restoring Switch Redundancy
Once the copy
This command will cause each element in the stack to reload.
Note. Connectivity to the switch is interrupted when this command is executed.
It may not be expedient to reboot a stack immediately after synchronizing the elements in the stack. It is possible to cause a synchronization reboot at a future time by setting time parameters in conjuction with the restore redundancy command, using the in or at keywords.
To schedule a resynchronization of a stack in 3 hours and 3 minutes, you would enter:
To schedule a resynchronization of a stack for June 30 at 8:00pm, you would enter:
Note. Scheduled resynchronization times should be entered in military format (i.e., a
To cancel a scheduled resynchronization enter:
