Assign the port to the ARP
MAD VLAN.
•
Assign the port to the VLAN as
an access port:
port access vlan
vlan-id
•
Assign the port to the VLAN as a
trunk port:
port trunk permit vlan vlan-id
•
Assign the port to the VLAN as a
hybrid port:
port hybrid vlan vlan-id

The link type of ARP MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.

Configuring ND MAD
When you use ND MAD, follow these guidelines:
•
Do not configure ND MAD on VLAN-interface 1.
•
Do not use the VLAN configured for ND MAD for any other purposes.
•
If an intermediate device is used, you can use common data links as ND MAD links. If no
intermediate device is used, set up dedicated ND MAD links between IRF member devices.
•
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. Make
sure there is only one ND 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.
{
Create an ND MAD VLAN and assign the ports on the ND MAD links to the VLAN.
{
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain
IDs for correct split detection.
To configure ND MAD:
