Mad Exclude Interface - H3C S5820X Series Irf Command Reference

Usage guidelines
LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate
H3C device that also supports LACP MAD packets.
When you use LACP MAD, follow these guidelines:
The intermediate device must be an H3C device that support extended LACP for MAD.
•
• If one IRF fabric uses another IRF fabric as the intermediate device for LACP MAD, you must 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.
•
Examples
# Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] mad enable
# Enable LACP MAD on Route-Aggregation 1, a Layer 3 dynamic aggregate interface.
<Sysname> system-view
[Sysname] interface route-aggregation 1
[Sysname-Route-Aggregation1] mad enable

mad exclude interface

Use mad exclude interface to exclude a physical network port from being shut down when the IRF fabric
transitions to the Recovery state upon detection of a multi-active collision.
Use undo mad exclude interface to restore the default MAD action on a physical network port.
Syntax
mad exclude interface interface-type interface-number
undo mad exclude interface interface-type interface-number
Default
All physical network ports but the IRF physical ports shut down when the IRF fabric transitions to the
Recovery state.
