Mad Exclude Interface - H3C S9800 Series Manual

You must set up a dynamic link aggregation group that spans all IRF member devices between the IRF
fabric and the intermediate device. To enable dynamic link aggregation, configure the link-aggregation
mode dynamic command on the aggregate interface.
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.
When you use the mad enable command, the system prompts you to enter a domain ID. If you do not
want to change the current domain ID, press Enter at the prompt.
NOTE:
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the irf domain
•
or mad enable command. The IRF domain IDs configured by using these commands overwrite each
other.
You can execute the mad enable command on any MDCs. If you change the IRF domain ID in one
•
MDC, the new IRF domain ID takes effect immediately on all MDCs.
Examples
# Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1

You need to assign a domain ID (range: 0-4294967295)

MAD LACP only enable on dynamic aggregation interface.

mad exclude interface

Use mad exclude interface to exclude a physical network port from being shut down when the IRF fabric
transits 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 interfaces and console port shut down when the IRF
fabric transits to the Recovery state.
