10. Assign the interface an IP
address.
11. Enable ND MAD.
Excluding a port from the shutdown action upon detection of
multi-active collision
CAUTION:
Do not exclude a VLAN interface and its Layer 2 ports from the shutdown action if the Layer 2 ports
are distributed on multiple member devices. The exclusion introduces IP collision risks because the
VLAN interface might be up on both active and inactive IRF fabrics.
By default, all ports (except the console and IRF physical interfaces) shut down automatically when
the IRF fabric transits to the Recovery state.
You can exclude a network 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 device.
•
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 network port to
not shut down when the IRF
fabric transits to the
Recovery state.
Recovering an IRF fabric
When the failed IRF link between two split IRF fabrics is recovered, all member devices in the
inactive IRF fabric automatically join the active IRF fabric as subordinate members. The network
ports that have been shut down by MAD automatically restore their original physical state, as shown
in
Figure
14.

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