Restrictions and guidelines
BFD MAD VLAN
• Do not enable BFD MAD on VLAN-interface 1.
• If you are using an intermediate device, perform the following tasks:
 On the IRF fabric and the intermediate device, create a VLAN for
BFD MAD.
 On the IRF fabric and the intermediate device, assign the ports of
BFD MAD links to the BFD MAD VLAN.
 On the IRF fabric, create a VLAN interface for the BFD MAD VLAN.
• Make sure the IRF fabrics on the network use different BFD MAD
VLANs.
• Make sure the BFD MAD VLAN 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.
