Usage guidelines
You can use ARP MAD with BFD MAD and ND MAD, but not with LACP MAD.
You cannot enable ARP MAD on VLAN-interface 1.
ARP MAD detects multi-active collisions by using extended ARP packets.
You can set up ARP MAD links between neighbor IRF members, or between each IRF member device and
an intermediate device.
If the intermediate device is also an IRF fabric, make sure the two IRF fabrics have different IRF domain
IDs for correct split detection. False detection causes IRF split.
When you use the mad arp 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 with 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 ARP MAD on VLAN-interface 3.
<Sysname> system-view
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad arp enable
You need to assign a domain ID (range: 0-4294967295)
