Assigning a member ID to each IRF member device
![[CAUTION: ]](images/caution.png) | CAUTION: In an IRF fabric, changing IRF member IDs might cause undesirable configuration changes and even data loss. Before you do that, back up the configuration and make sure you fully understand the impact on your network. For example, all member devices in an IRF fabric are the same model. If you swapped the IDs of any two members, their interface settings would also be swapped. | |
To create an IRF fabric, you must assign a unique IRF member ID to each member device.
To prevent any undesirable configuration change or data loss, avoid changing member IDs after the IRF fabric is formed.
The new member ID takes effect at a reboot. After the device reboots, the settings on all member ID-related physical resources (including common physical network ports) are removed, regardless of whether you have saved the configuration.
To assign a member ID to a device:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Assign a member ID to a member device. | irf member member-id renumber new-member-id | The default IRF member ID is 1. |
3. (Optional.) Save the configuration. | save | If you have bound physical interfaces to IRF ports or assigned member priority, save the configuration before rebooting the device so these settings can continue to take effect after the reboot. |
4. Reboot the device. | reboot [ slot slot-number ] [ force ] | N/A |
