Step
4.
Configure the aggregation
group to operate in dynamic
aggregation mode.
5.
Enable LACP MAD.
6.
Return to system view.
7.
Enter Ethernet interface
view or interface range
view.
8.
Assign the Ethernet port or
the range of Ethernet ports
to the specified aggregation
group.
Configuring BFD MAD
Before you configure BFD MAD, choose a BFD MAD link scheme as described in
As a best practice, connect the BFD MAD links after you finish the BFD MAD configuration.
When you configure BFD MAD settings, follow these restrictions and guidelines:
Category
BFD MAD VLAN
BFD MAD VLAN and
feature compatibility
MAD IP address
Command
interface-number
link-aggregation mode dynamic
mad enable
quit
•
Enter interface range view:
interface range { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-24>
•
Enter Ethernet interface view:
interface interface-type
interface-number
port link-aggregation group
number
Restrictions and guidelines
•
Do not enable BFD MAD on VLAN-interface 1.
•
If you are using an intermediate device, perform the following tasks on
both the IRF fabric and the intermediate device:
Create a VLAN and VLAN interface for BFD MAD.
Assign the ports of BFD MAD links to 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 the port is not on the
BFD MAD link. For example, if you have assigned the port to all VLANs
by using the port trunk permit vlan all command, use the undo port
trunk permit command to exclude the port from the BFD MAD VLAN.
Do not use the BFD MAD VLAN for any purpose other than configuring BFD
MAD.
•
Configure only the mad bfd enable and mad ip address commands on
the VLAN interface used for BFD MAD. If you configure other features,
both BFD MAD and other features on the interface might run incorrectly.
•
Disable the spanning tree feature on all Layer 2 Ethernet ports in the BFD
MAD VLAN. The MAD feature is mutually exclusive with the spanning
tree feature.
•
Use the mad ip address command instead of the ip address command
to configure MAD IP addresses on the BFD MAD-enabled VLAN

Remarks
By default, an aggregation
group operates in static
aggregation mode.
Perform this step also on the
intermediate device.
By default, LACP MAD is
disabled.
N/A
To assign a range of ports to
the aggregation group, enter
interface range view.
To assign one port to the
aggregation group, enter
Ethernet interface view.
Multi-member link aggregation
is allowed.
Also perform this step on the
intermediate device.
