The ports that have been shut down by MAD come up when the member devices reboot to join the recovered IRF fabric. If auto recovery fails because the current master fails or any other exception occurs, use the mad restore command to manually recover the member devices and bring up the ports. Examples # Exclude Ten-GigabitEthernet 2/0/17 from being shut down when the MAD status transits to Recovery. system-view [Sysname] mad exclude interface ten-gigabitethernet 2/0/17 Related commands mad restore mad ip address Use mad ip address to assign a MAD IP address to an IRF member on a VLAN interface for BFD MAD. Use undo mad ip address to delete a MAD IP address.

The ports that have been shut down by MAD come up when the member devices reboot to join the
recovered IRF fabric. If auto recovery fails because the current master fails or any other exception occurs,
use the
mad restore
command to manually recover the member devices and bring up the ports.

Parameters
ip-address
: Specifies an IP address in dotted decimal notation. This IP address is bound to an IRF member
for BFD detection and is called a "MAD IP address."
mask
: Specifies a subnet mask in decimal dotted notation.
mask-length
: Specifies a subnet mask in length in the range of 0 to 32.
member
member-id
: Specifies the ID of an IRF member.
Usage guidelines
To use BFD MAD, configure a MAD IP address on a BFD MAD-enabled VLAN interface for each IRF
member, and make sure all the MAD IP addresses are on the same subnet.
To avoid problems, only use the
mad ip address
command to configure IP addresses on the BFD
MAD-enabled VLAN interface. Do not configure an IP address with the
ip address
command or
configure a VRRP virtual address on the BFD MAD-enabled VLAN interface.
The master tries to establish BFD sessions with other member devices by using its MAD IP address as the
source IP address:
•
If the IRF fabric is integrated, only the MAD IP address of the master is effective, and the master
cannot establish a BFD session with any other member. If you execute the
display bfd session
command, the state of the BFD sessions is
Down
