Step
6. Assign the port or the range
of ports to the BFD MAD
VLAN.
7. Return to system view.
8. Enter VLAN interface view.
9. Enable BFD MAD.
10. Configure a MAD IP address
for a member on the VLAN
interface.
Excluding a port from the shutdown action upon detection of multi-active collision
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.
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 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 port to not shut
down when the IRF fabric
transits to the Recovery state.
Command
•
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 }
quit
interface vlan-interface
interface-number
mad bfd enable
mad ip address ip-address { mask |
mask-length } member member-id

Remarks
The link type of BFD MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.
N/A
N/A
By default, BFD MAD is
disabled.
By default, no MAD IP addresses
are configured on any VLAN
interfaces.
Repeat this step to assign a MAD
IP address to each member
device on the VLAN interface.
The MAD IP addresses identify
the member devices and must
belong to the same subnet.
Remarks
N/A
By default, all network ports on a
Recovery-state IRF fabric are shut
down, except for the IRF physical
interfaces and console port.
