Excluding a port from the shutdown action upon
detection of multi-active collision
By default, all ports except the console and IRF physical interfaces shut down automatically when the IRF
fabric transits to the Recovery state.
You can exclude a network port from the shutdown action for management or other special purposes. For
example:
• Exclude a port from the shutdown action so you can Telnet to the port for managing the device.
• Exclude a VLAN interface and its Layer 2 ports from the shutdown action so you can log in through
the VLAN interface.
To configure a port to not shut down when the IRF fabric transits to the Recovery state:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a network port to
not shut down when the IRF
fabric transits to the
Recovery state.

By default, all network ports on a
Recovery-state IRF fabric are shut
down, except for the IRF physical
interfaces and console port.
Recovering an IRF fabric
After the failed IRF link between two split IRF fabrics is recovered, reboot the member devices in either
fabric. This action merges all member devices in the inactive IRF fabric to the active IRF fabric as
subordinates.
• If you reboot the inactive IRF fabric, the network ports that have been shut down by MAD restore
their original physical state automatically.
• If you reboot the active IRF fabric, you must execute the mad restore command after the reboot. This
command restores the original physical state of the network ports that have been shut down by
MAD.
