Usage guidelines
Do not configure ARP MAD together with LACP MAD, because they handle collisions differently.
Do not configure ARP MAD together with BFD MAD. ARP MAD requires the spanning tree feature, but BFD MAD is mutually exclusive with the spanning tree feature. At the same time, ARP MAD handles collisions differently than BFD MAD.
When you configure ARP MAD, follow these restrictions and guidelines:

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 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.
You can execute the mad arp enable command on any MDCs. If you change the IRF domain ID in one MDC, the new IRF domain ID takes effect immediately on all MDCs.
