Setting Unit IDs for
Switches
You can use the command in the following table to set unit IDs for Switches.
Make sure to set different unit IDs for different Switches in a stack. On the

number the Switches to constitute a stack, so that each Switch has a unique unit
ID in the stack.
Perform the following configuration in System View.
Table 162 Setting unit IDs for Switches
■ If the modified unit ID does not exist in the stack, the Switch sets its priority to
5 and saves it in the unit Flash memory.
■ If the modified unit ID is an existing one, the Switch prompts you to confirm if
you really want to change the unit ID. If you choose to change, the existing
unit ID is replaced and the priority is set to 5. Then you can use the
fabric
save-unit-id
command to save the modified unit ID into the unit Flash
memory and clear the information about the existing one.
