Usage guidelines
LACP MAD handles collisions differently than ARP MAD and ND MAD. To avoid conflicts, do not
enable LACP MAD together with ARP MAD and ND MAD on an IRF fabric.
LACP MAD requires a 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.
Restrictions and guidelines
•
Make sure all the MAD IP addresses are on the same subnet.
Restrictions and guidelines
Connect a management Ethernet port on each member device to the
common Ethernet ports on the intermediate device.
•
On the intermediate device, create a VLAN for BFD MAD, and assign the
ports used for BFD MAD to the VLAN. On the IRF fabric, you do not need
to assign the management Ethernet ports to the VLAN.
•
Make sure the IRF fabrics on the network use different BFD MAD
VLANs.
•
Make sure the BFD MAD VLAN on the intermediate device contains only
ports on the BFD MAD links.
•
mad ip address
Use the
command to configure MAD IP addresses on the BFD MAD-enabled
management Ethernet ports.
•
Make sure all the MAD IP addresses are on the same subnet.
