ARP MAD VLAN
• Do not enable ARP MAD on VLAN-interface 1.
• If you are using an intermediate device, perform the following tasks:
 On the IRF fabric and the intermediate device, create a VLAN for
ARP MAD.
 On the IRF fabric and the intermediate device, assign the ports of
ARP MAD links to the ARP MAD VLAN.
 On the IRF fabric, create a VLAN interface for the ARP MAD VLAN.
• As a best practice, do not use the ARP MAD VLAN for any other
