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.
ARP MAD detects multi-active collisions by using extended gratuitous ARP packets.
You can use ARP MAD with BFD MAD, but not with LACP MAD.
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.
You must enter the domain ID when you use the
mad arp enable
command.
Examples
# Enable ARP MAD on VLAN-interface 3.
