When you configure ND MAD on a management Ethernet port, follow these restrictions and
guidelines:

ND MAD and feature
configuration
When you use the mad nd enable command, the system prompts you to enter a domain ID. If you
do not want to change the current domain ID, press enter at the prompt.
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the following
commands: irf domain , mad enable , mad arp enable , or mad nd enable . The IRF domain
IDs configured by using these commands overwrite each other.
Examples
# Enable ND MAD on VLAN-interface 3.
<Sysname> system-view
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad nd enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]: 1
The assigned domain ID is: 1
Related commands
irf domain
mad restore
Use mad restore to restore the normal MAD state of the IRF fabric in Recovery state.
Syntax
mad restore
Restrictions and guidelines
•
As a best practice, do not use the ND 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 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.
•
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.
On the intermediate device, create a VLAN for ND MAD, and assign the ports
used for ND 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.
