Excluding a port or interface from the shutdown action upon detection of multi-active collision
By default, all ports and interfaces except for the console port and IRF physical interfaces shut down automatically when the IRF fabric transits to the Recovery state.
You can exclude a network port or 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.
Configuration restrictions and guidelines
When you configure this feature, follow these restrictions and guidelines:
If the Layer 2 ports of a VLAN interface are distributed on multiple member devices, the exclusion operation might introduce IP collision risks. The VLAN interface might be up on both active and inactive IRF fabrics.
Do not exclude the following ports and interfaces from the shutdown action:
Aggregate interfaces used for MAD and their member ports.
VLAN interfaces used for MAD and the Ethernet ports in the VLANs.
Management Ethernet ports used for MAD.
