Restrictions and guidelines
BFD MAD VLAN
• On the intermediate device (if any), assign the ports on the BFD MAD
links to the same VLAN. Do not assign the ports to an aggregate
interface. If the ports are hybrid ports, make sure these ports are
untagged members of their PVIDs.
• If the intermediate device acts as a BFD MAD intermediate device for
multiple IRF fabrics, assign different BFD MAD VLANs to the IRF fabrics.
• Do not use the BFD MAD VLAN on the intermediate device for any
purposes other than BFD MAD.
• Make sure the BFD MAD VLAN on the intermediate device contains only
ports on the BFD MAD links. Exclude a port from the BFD MAD VLAN if
that port is not on a BFD MAD link. If you have assigned that port to all
VLANs by using the port trunk permit vlan all command,
use the undo port trunk permit command to exclude that port
from the BFD MAD VLAN.
BFD MAD-enabled Layer 3
aggregate interface and
feature compatibility
Use only the
mad bfd enable
and
mad ip address
commands on
the BFD MAD-enabled interface. If you configure other features, both BFD
MAD and other features on the interface might run incorrectly.
MAD IP address
• To avoid network issues, only use the
mad ip address
command to
configure IP addresses on the BFD MAD-
enabled interface. Do not
configure an IP address by using the ip address
command or
configure a VRRP virtual address on the BFD MAD-enabled interface.
• Make sure all the MAD IP addresses are on the same subnet.

Usage guidelines
LACP MAD requires an H3C device that supports extended LACPDUs for MAD to act as the
intermediate device. You must set up a dynamic link aggregation group that spans all IRF member
devices between the IRF fabric and the intermediate device. To enable dynamic link aggregation,
configure the
link-aggregation mode dynamic command on the aggregate interface.
