Preconfiguring IRF member devices in standalone
mode
Perform the tasks in this section on every IRF member device. These settings take effect on each member
device after their operating mode changes to IRF.
Assigning a member ID to each IRF member device
A device by default operates in standalone mode without an IRF member ID. You must assign it a unique
IRF member ID before changing its operating mode to IRF.
Execute the display irf configuration command and look at the MemberID field. If the device has no IRF
member ID, the field displays two hyphens (--).
The member ID assigned to a device is saved in both active and standby MPUs of the device. If the
standby MPU has a different member ID than the active MPU, for example, because of an MPU
replacement, the member ID in the active MPU takes effect and is automatically updated to the standby
MPU.
To set a member ID for the device in standalone mode:
Step Command Remarks
1. Enter system view. system-view N/A
2. Assign an IRF member ID to
the device.
irf member member-id
By default, the device has no IRF
member ID.
Specifying a priority for each member device

higher the priority, the higher the possibility.
To specify a priority for the device in standalone mode:
Step Command Remarks
1. Enter system view. system-view N/A

device.
