When you configure ARP MAD that uses management Ethernet ports, follow these restrictions and
guidelines:

ARP MAD and feature
configuration
Configuring ARP MAD on a VLAN interface
1. Enter system view.
system-view
2. Assign a domain ID to the IRF fabric.
irf domain domain-id
The default IRF domain ID is 0.
3. Configure the IRF bridge MAC address to change as soon as the address owner leaves.
undo irf mac-address persistent
By default, the IRF bridge MAC address does not change after the address owner leaves.
4. Create a VLAN dedicated to ARP MAD.
vlan vlan-id
By default, only VLAN 1 exists.
Do not configure ARP MAD on VLAN-interface 1.
Perform this task also on the intermediate device (if any).
5. Return to system view.
quit
6. Enter Ethernet interface view or interface range view.
Enter Ethernet interface view.

interface interface-type interface-number
Enter interface range view. Choose one of the following commands:

interface range { interface-type interface-number [ to
interface-type interface-number ] } &<1-24>
Restrictions and guidelines
•
Run the spanning tree feature between the IRF fabric and the
intermediate device to ensure that there is only one ARP MAD link in
forwarding state. For more information about the spanning tree feature
and its configuration, see Layer 2—LAN Switching Configuration Guide.
•
Enable the IRF fabric to change its bridge MAC address as soon as the
address owner leaves.
•
If the intermediate device is also an IRF fabric, assign the two IRF fabrics
different domain IDs for correct split detection.
Restrictions and guidelines
Connect a management Ethernet port on each member device to the common
Ethernet ports on the intermediate device. To avoid ARP MAD failure caused
by an active/standby MPU switchover, connect the management Ethernet
ports on each MPU to the intermediate device.
On the intermediate device, create a VLAN for ARP MAD, and assign the
ports used for ARP MAD to the VLAN. On the IRF fabric, you do not need to
assign the management Ethernet ports to the VLAN.
•
Enable the IRF fabric to change its bridge MAC address as soon as the
address owner leaves.
•
If the intermediate device is also an IRF fabric, assign the two IRF fabrics
different domain IDs for correct split detection.
