ARP MAD VLAN
ARP MAD and feature
configuration
To configure ARP MAD:
Step
1.
Enter system view.
2.
Assign a domain ID to the
IRF fabric.
3.
Configure the IRF bridge
MAC address to change as
soon as the address owner
leaves.
4.
Create a VLAN dedicated to
ARP MAD.
5.
Return to system view.
6.
Enter Ethernet interface
view.
7.
Assign the port to the ARP
MAD VLAN.
8.
Return to system view.
9.
Create the VLAN interface
and enter VLAN interface
view.
10. Assign the interface an IP
address.
11. Enable ARP MAD.
Restrictions and guidelines
•
Do not enable ARP MAD on VLAN-interface 1.
•
If you are using an intermediate device, perform the following tasks on
both the IRF fabric and the intermediate device:
Create a VLAN and VLAN interface for ARP MAD.
Assign the ports of ARP MAD links to the ARP MAD VLAN.
•
Do not use the ARP MAD VLAN for any other purposes.
If an intermediate device is used, make sure the following requirements are
met:
•
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.

The default IRF domain ID is 0.
By default, the IRF bridge MAC
address remains unchanged for

owner leaves.
The default VLAN on the device
is VLAN 1.
