Excluding a port from the shutdown action on detection of multi-active collision
By default all service ports of an IRF virtual device except the IRF ports are shut down when the IRF

the up state for special purposes such as telnet connection, exclude it from the shutdown action.
To configure a port not to shut down when the IRF virtual device transits to recovery state:
To do...
