unit-id {0 | 1}
The unit IDs are used for internal system operations.
To explicitly configure the default values on each peer switch, use the unit-id command.
Configure a different unit ID (0 or 1) on each peer switch.
Use this command to minimize the time required for the VLT system to determine the unit ID assigned to each peer switch
when one peer switch reboots.
