6. Assign the port or the range
of ports to the BFD MAD
VLAN.
• Assign the port to the VLAN as an
access port:
port access vlan vlan-id
• Assign the port to the VLAN as a
trunk port:
port trunk permit vlan vlan-id
• Assign the port to the VLAN as a
hybrid port:
port hybrid vlan vlan-id { tagged |
untagged }
Choose one command
depending on the port type.
BFD MAD has no requirements
for link type of the detection port.
The default link type of a port is
access.
7. Return to system view.

8. Enter VLAN interface view.

9. Enable BFD MAD.
mad bfd enable
By default, BFD MAD is
disabled.
10. Configure a MAD IP address
for a member on the VLAN
interface.
mad ip address ip-address { mask |
mask-length } member member-id
By default, no MAD IP address is
configured on any VLAN
interface.
Repeat this step to assign a MAD
IP address to each member
device on the VLAN interface.
Excluding a port from the shutdown action upon detection of multi-active collision
By default, all ports except the console and physical IRF ports shut down automatically 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 device.
• Exclude a VLAN interface and its Layer 2 ports from the shutdown action, so you can log in through
the VLAN interface.
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 active and inactive IRF fabrics.
To configure a port to not shut down when the IRF fabric transits to the Recovery state:
