MAD and IRF domain restrictions

When you configure MAD, follow these restrictions and guidelines:
• If LACP 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 irf
•
domain or mad enable command. The IRF domain IDs configured by using these commands
overwrite each other.
LACP MAD handles collisions differently than BFD MAD. To avoid conflicts, do not enable LACP
•
MAD together with BFD MAD in an IRF fabric.
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.

IRF merge restrictions

If the IRF fabric splits, do not change the IRF settings on any IRF member devices before they reunite.

Configuration backup

HP recommends that you back up the next-startup configuration file on a device before adding the device
to an IRF fabric as a subordinate.
A subordinate device's next-startup configuration file might be overwritten if the master and the
subordinate use the same file name for their next-startup configuration files. You can use the backup file
to restore the original configuration after removing the subordinate from the IRF fabric.
