To configure a port to not shut down when the IRF fabric transits to the Recovery state: Step Command 1. Enter system view. system-view 2. Configure a network port to not shut down when the IRF mad exclude interface interface-type fabric transits to the interface-number Recovery state. Remarks N/A 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 When the failed IRF link between two split IRF fabrics is recovered, all member devices in the inactive IRF fabric (in Recovery state) join the active IRF fabric as subordinate members automatically, and the network ports that have been shut down by MAD restore their original physical state automatically, as shown in Figure 12. Figure 12 Recovering the IRF fabric If the active IRF fabric has failed, for example, because of device or link failures, before the IRF link is recovered (see Figure 13), use the mad restore command on the inactive IRF fabric to change its MAD state to Detect and bring up all physical ports that were shut down by MAD. After you repair the IRF link, the two parts merge into a unified IRF fabric. 31

Recovering an IRF fabric
When the failed IRF link between two split IRF fabrics is recovered, all member devices in the inactive IRF
fabric (in Recovery state) join the active IRF fabric as subordinate members automatically, and the
network ports that have been shut down by MAD restore their original physical state automatically, as
shown in
Figure 12
.

Recovering the IRF fabric
If the active IRF fabric has failed, for example, because of device or link failures, before the IRF link is
recovered (see
Figure 13
), use the
mad restore
command on the inactive IRF fabric to change its MAD
state to Detect and bring up all physical ports that were shut down by MAD. After you repair the IRF link,
the two parts merge into a unified IRF fabric.
