Excluding a port from the shut down action upon detection of multi-active collision
By default, all service ports of an IRF fabric except the console and physical IRF ports shut down when the
IRF fabric transits to recovery state upon detection of a multi-active collision. You can exclude a service
port from the shut down action for management or other special purposes. For example, you can exclude
a port from the shut down action, so you can telnet to the port for managing the switch. For another
example, you can exclude a VLAN interface and its Layer 2 Ethernet interface from the shut down action,
so you can log in through the VLAN interface.
To configure a port not to shut down when the IRF fabric changes to recovery state:
To do...
Enter system view
Configure a service port not to
shut down when the IRF fabric
transits to recovery state
Use the command...

Trunk port port trunk permit vlan vlan-id
to
Hybrid port port hybrid vlan vlan-id
