Mad Ip Address - HPE FlexFabric 12900E Command Reference Manual

The ports and interfaces 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 and interfaces.
Examples
# Exclude HundredGigE 1/1/0/1 from being shut down when the MAD status transits to Recovery.
<Sysname> system-view
[Sysname] mad exclude interface hundredgige 1/1/0/1

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.
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 port or interface.
The master attempts 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 takes effect. 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.
•
When the IRF fabric splits, the IP addresses of the masters in the partitioned IRF fabrics take
effect. The masters can establish a BFD session. If you execute the display bfd session
command, the state of the BFD session between the two devices is Up.
