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.

To configure a port to not shut down when the IRF fabric transits to the Recovery state:

Step Command

Remarks

Enter system view.

system-view

N/A

Configure a port to not shut
down when the IRF fabric
transits to the Recovery
state.

mad exclude interface

interface-type interface-number

By default, all network ports on
a Recovery-state IRF fabric are
shut down, except for the IRF
physical ports and console port.

Recovering an IRF fabric

After the failed IRF link between two split IRF fabrics is recovered, log in to the Recovery-state IRF
fabric. Use the

reboot

command to reboot all the members in the IRF fabric. After these member

switches join the Active-state IRF fabric as subordinates, IRF merge is complete, as shown in

Figure

Figure 11 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

Figure 12

), use the

mad restore

command on the Recovery-state fabric to change

its state to Active for forwarding traffic. After you repair the IRF link, the two parts merge into a unified
IRF fabric.
