Configuring LACP MAD
When you use LACP MAD, follow these guidelines:
The intermediate device must be an HP device that support 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. False detection causes IRF split.
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 also on the intermediate device.
•
To configure LACP MAD:
Step
1.
Enter system view.
Advantages
•
Detection speed is fast.
•
No intermediate device is
required.
•
Intermediate device, if used,
can come from any vendor.
•
No intermediate device is
required.
•
Intermediate device, if used,
can come from any vendor.
•
Requires no MAD dedicated
ports.

Disadvantages
•
Requires MAD dedicated
physical ports and Layer
3 interfaces, which
cannot be used for
transmitting user traffic.
•
If no intermediate device
is used, the IRF members
must be fully meshed.
•
If an intermediate device
is used, every IRF
member must connect to
the intermediate device.
•
Detection speed is slower
than BFD MAD and LACP
MAD.
•
The spanning tree feature
must be enabled.
•
Detection speed is slower
than BFD MAD and LACP
MAD.
•
The spanning tree feature
must be enabled.

Application scenario
•
No special
requirements for
network scenarios.
•
If no intermediate
device is used, this
mechanism is only
suitable for IRF fabrics
that have a small
number of members
that are
geographically close
to one another.
