1-7After an IRF fabric is established, you can use the following command to change the unit IDs of theswitches in the IRF fabric.Follow these steps to set a unit ID to a new value:To do… Use the command… RemarksEnter system view system-view —Set a unit ID to a new value change unit-id unit-id1 to { unit-id2 |auto-numbering } Optionalz Unit IDs in an IRF fabric are not always arranged in order of 1 to 8.z Unit IDs of an IRF fabric can be inconsecutive.After you change the unit ID of switches, the following operations are performed.z If the modified unit ID does not exist in the IRF fabric, the system sets its priority to 5 and saves it inthe unit Flash memory.z If the modified unit ID is an existing one, the system prompt you to confirm if you really want tochange the unit ID. If you choose to change, the existing unit ID is replaced and the priority is set to5. Then you can use the fabric save-unit-id command to save the modified unit ID into the unitFlash 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 fabricsave-unit-id command to save the modified unit ID into the unit Flash memory and clear theinformation about the existing one.Priority is the reference for FTM program to perform automatic numbering. The value of priority can be5 or 10. Priority 5 means the switch adopts manual numbering, and priority 10 means the switch adoptsautomatic 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 localunit ID in the unit Flash memory. When you restart the switch, it can load the unit ID configurationautomatically.Follow these steps to save the unit ID of each unit in the IRF fabric:
