Configuring LACP MAD

When you use LACP MAD, follow these guidelines:
The intermediate device must be a device that supports extended LACP for MAD.
•
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for
•
correct split detection.
Use dynamic link aggregation mode. MAD is LACP dependent. Even though LACP MAD can be
•
configured on both static and dynamic aggregate interfaces, it takes effect only on dynamic
aggregate interfaces.
Configure link aggregation settings on the intermediate device.
•
To configure LACP MAD:
Step
Enter system view.
1.
2. Assign a domain ID to the IRF
fabric.
3. Create a Layer 2 aggregate
interface and enter
aggregate interface view.
4. Configure the aggregation
group to operate in dynamic
aggregation mode.
5. Enable LACP MAD.
6. Return to system view.
Advantages
•
No intermediate device is
required.
•
Intermediate device, if used,
can come from any vendor.
•
Does not require MAD
dedicated ports.

Disadvantages
•
Detection speed is slower
than BFD MAD and LACP
MAD.
•
The spanning tree feature
must be enabled.

Application scenario
Spanning tree-enabled
non-link aggregation IPv4
network scenario.
For information about
ARP, see Layer 3—IP
Services Configuration
Guide.
Spanning tree-enabled
non-link aggregation IPv6
network scenario.

Remarks
N/A
The default IRF domain ID is 0.
Perform this step also on the
intermediate device.
By default, an aggregation
group operates in static
aggregation mode.
Perform this step also on the
intermediate device.
By default, LACP MAD is
disabled.
