Note:
Unit IDs in an IRF fabric are not always arranged in order of 1 to 8.
Unit IDs of an IRF fabric can be inconsecutive.
After you change the unit ID of switches, the following operations are performed.
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.
If the modified unit ID is an existing one, the system prompt 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.
If auto-numbering is selected, the system sets the unit ID 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.
Note:
Priority is the reference for FTM module to perform automatic numbering. The value
of priority can be 5 or 10. A smaller value represents a higher priority. Priority 5 means
the switch adopts manual numbering, and priority 10 means the switch adopts
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.
