Excluding a service interface from the shutdown action upon detection of multi-active collision

	CAUTION: Do not exclude a VLAN interface and its Layer 2 ports from the shutdown action if the Layer 2 ports are distributed on multiple member devices. The exclusion introduces IP collision risks because the VLAN interface might be up on both active and inactive IRF fabrics.

By default, all service interfaces except for the IRF physical interfaces shut down automatically when the IRF fabric transits to the Recovery state.

You can exclude a service interface 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 service interface to not shut down when the IRF fabric transits to the Recovery state:
