You must assign a domain ID for an IRF virtual device before enabling LACP MAD detection.
z
Although devices with different domain IDs can form an IRF virtual device, you are recommended to
assign the same domain ID to the members of the same IRF virtual device; otherwise, the LACP
MAD detection function cannot function properly.

To display the domain IDs and verify your configuration, execute the
display irf
command in any

Setting a Member ID for a Device
The member ID of a device defaults to 1. During the establishment of an IRF virtual device, if the
member IDs of two devices are duplicate, you need to manually change the member IDs. Therefore,
you are recommended to plan and configure the member ID for each member before configuring an
IRF virtual device.
For a device that is already a member of an IRF virtual device, use the commands in
Table 1-3
to
change the member ID of the device. Your modification takes effect at the reboot of the device.
For a device that is not a member of an IRF virtual device, you are recommended to set its member ID
as follows:
1) Plan the member ID in advance. View the member IDs of all member devices, and select an
unused ID for the new device.
2) Log in to the device, and change its member ID to the unused ID found out in step 1.
3) Save the current configuration. Power off the device, connect the device to the IRF virtual device
with SFP+ cables or fibers and power it on. Use the configuration introduced in this section to
enable IRF on the device and add it into the IRF virtual device.
