Default level
3: Manage level
Parameters
None
Description
Use
mad arp enable
to enable ARP MAD.
Use
undo mad arp enable
to disable ARP MAD.
By default, ARP MAD is disabled.
You can set up ARP MAD links between neighbor IRF members or between each IRF member device and
an intermediate device.
When you configure ARP MAD, follow these guidelines:
•
If an intermediate device is used, you can use common data links as ARP MAD links. If no
intermediate device is used, set up dedicated ARP MAD links between IRF member devices.
•
Use a VLAN dedicated to ARP MAD.
•
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.
{
Enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
{
Create the ARP MAD VLAN and assign the ports on the ARP MAD links to the VLAN.
•
If the intermediate device is in an IRF fabric, assign this fabric a different domain ID than the ARP
MAD-enabled fabric to avoid false detection of IRF split.
