z If the modified unit ID does not exist in the IRF fabric, the system sets its priority to 5 and saves it in
the unit Flash memory.
z If the modified unit ID is an existing one, the system prompts you to confirm if you really want to
change the unit ID. If you choose to change it, 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.
z If auto-numbering is selected, the system sets the unit priority to 10. 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.
Priority is the reference for FTM program to perform automatic numbering. The value of priority can be
5 or 10. Priority 5 means the switch adopts manual numbering, and priority 10 means the switch adopts
automatic numbering. Manual numbering has a higher priority than automatic numbering.
After the configuration of numbering, you can use the following command in the table to save the local
unit ID in the unit Flash memory. When you restart the switch, it can load the unit ID configuration
automatically.
