When you configure BFD MAD on a Layer 3 aggregate interface, follow these restrictions and
guidelines:
Category
BFD MAD-enabled Layer 3
aggregate interface
Restrictions and guidelines
Do not use the BFD MAD VLAN for any purposes other than configuring BFD
MAD.
•
Use only the mad bfd enable
on the BFD MAD-enabled VLAN interface. If you configure other
features, both BFD MAD and other features on the interface might run
incorrectly.
•
Disable the spanning tree feature on any Layer 2 Ethernet ports in the
BFD MAD VLAN. The MAD feature is mutually exclusive with the
spanning tree feature.
•
To avoid network issues, only use the
configure IP addresses on the BFD MAD-enabled VLAN interface. Do
not configure an IP address by using the
configure a VRRP virtual address on the BFD MAD-enabled VLAN
interface.
•
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.
Restrictions and guidelines
•
Make sure the Layer 3 aggregate interface operates in static
aggregation mode.
•
Make sure the member ports in the aggregation group do not exceed the
maximum number of Selected ports allowed for an aggregation group. If
the number of member ports exceeds the maximum number of Selected
ports, some member ports cannot become Selected. BFD MAD will be
unable to work correctly and its state will change to Faulty.
