CAUTION:
Excluding a VLAN interface and its Layer 2 ports from the shutdown action introduces IP collision risks
because the VLAN interface might be active on both the IRF fabric in Active state and the IRF fabric in
Recovery state.
By default, all ports except the console and physical IRF ports automatically shut down when the IRF
fabric transits to the Recovery state.
You can exclude a 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 switch.
•
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
1.
Enter system view.
2.
Configure a port to not shut
down when the IRF fabric
transits to the Recovery state.
Recovering an IRF fabric
After the failed IRF link between two split IRF fabrics is recovered, log in to the Recovery-state IRF fabric,
and use the reboot command to reboot all its members. After these member switches join the Active-state
IRF fabric as subordinates, IRF merge is complete, as shown in
Figure 10 Recovering the IRF fabric
If the Active-state fabric has failed, for example, because of device or link failures, before the IRF link is
recovered (see
to Active for forwarding traffic. After you repair the IRF link, the two parts merge into a unified IRF fabric.

its network ports but the IRF
physical ports and console port
are shut down.
