Operation Manual – IRF Fabric
H3C S5600 Series Ethernet Switches
After an IRF fabric is established, you can use the following command to change the
unit IDs of the switches in the IRF fabric.
Follow these steps to set a unit ID to a new value:
Enter system view
Set a unit ID to a new
value
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 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 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.
Follow these steps to save the unit ID of each unit in the IRF fabric:
