To do...
Assign a domain ID to the IRF
fabric
Create an
aggregate
interface and
enter
aggregate
interface view
Configure the aggregation group
to work in dynamic aggregation
mode
Enable LACP MAD detection
Return to system view
Enter Ethernet interface view
Assign the current Ethernet
interface to the specified
aggregation group
Configuring BFD MAD
BFD MAD detection mechanism
1.
BFD MAD is implemented with the BFD protocol. To configure BFD MAD detection, configure a MAD IP
address on a BFD-enabled Layer 3 interface for each member switch. This MAD address identifies the
member during BFD MAD detection. The MAD IP addresses assigned to the member switches must
belong to the same network segment.
When the IRF fabric is operating normally, only the MAD IP address of the master is effective and
•
the BFD session is down.
When the IRF fabric partitions, the MAD IP addresses of the masters in different IRF fabrics become
•
effective to activate the BFD sessions to detect for multi-active IRF fabric collision.
Network requirements
2.
BFD MAD detection can work with or without intermediate switches. In a BFD MAD network without an
intermediate switch, connect all IRF member switches with dedicated BFD MAD links in the full mesh
topology, as shown in
Use the command...

Remarks
Required if the intermediate
device is an IRF fabric.
By default, the domain ID of an
IRF fabric is 0.
Required
Use either command.
Required
By default, the aggregation
group works in static
aggregation mode.
Required
Disabled by default.
Even though this command can
be configured on both static and
dynamic aggregate interfaces, it
takes effect only on dynamic
aggregate interfaces. This is
because this detection approach
depends on LACP.
