Mad Ip Address - H3C MSR Series Command Reference Manual

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
# (Centralized devices.) Exclude GigabitEthernet 1/0/1 from being shut down when the MAD status
transits to Recovery.
<Sysname> system-view
[Sysname] mad exclude interface gigabitethernet1/0/1
# (Distributed devices.) Exclude GigabitEthernet 1/2/0/1 from being shut down when the MAD status
transits to Recovery.
<Sysname> system-view
[Sysname] mad exclude interface gigabitethernet 1/2/0/1

mad ip address

Use mad ip address to assign a MAD IP address to an IRF member device for BFD MAD.
Use undo mad ip address to delete the MAD IP address for an IRF member device.
Syntax
mad ip address ip-address { mask | mask-length } member member-id
undo mad ip address ip-address { mask | mask-length } member member-id
Default
No MAD IP address is configured for an IRF member device.

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 for each IRF member. Make sure all the MAD IP
addresses are on the same subnet.
Do not configure a MAD IP address by using the ip address command or configure a VRRP virtual
address on the BFD MAD-enabled interface.
The master attempts to establish BFD sessions with other member devices by using its MAD IP
address as the source IP address.
