Multichassis link aggregation

For high availability, connect a downstream device to each IRF member device, and assign the links to
one link aggregation group.

MAD and IRF domain restrictions

When you configure MAD, follow these restrictions and guidelines:
If LACP MAD, ARP MAD, or ND MAD runs between two IRF fabrics, assign each fabric a unique
•
IRF domain ID. (For BFD MAD, this task is optional.)
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.
LACP MAD handles collisions differently than BFD MAD, ARP MAD, and ND MAD. To avoid
•
conflicts, do not enable LACP MAD together with any of those mechanisms in an IRF fabric.
However, you can configure BFD MAD, ARP MAD, and ND MAD together in an IRF fabric for
prompt IRF split detection.
• To prevent a port from being shut down when the IRF fabric transits to the Recovery state, use the
mad exclude interface command. To bring up ports in a Recovery-state IRF fabric, use the mad
restore command instead of the undo shutdown command. The mad restore command activates
the Recovery-state IRF fabric.

Other configuration guidelines

If a subordinate device uses the same next-startup configuration file name as the master device, the
•
file might be overwritten depending on the configuration file management settings. To continue to
