Mad Exclude Interface - H3C S6812 Series Command Reference Manual

An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the following
commands: irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domain IDs
configured by using these commands overwrite each other.
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] link-aggregation mode dynamic
[Sysname-Bridge-Aggregation1] mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]: 1
The assigned
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 configure the IRF fabric to shut down a physical network port
when it transits to the Recovery state upon detection of a multi-active collision.
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 ports shut down when the IRF
fabric transits to the Recovery state.
Views

Predefined user roles
network-admin
Parameters
interface-type interface-number: Specifies a port by its type and number.
Usage guidelines
If a port must be kept in up state for special purposes such as Telnet connection, exclude the port
from the shutdown action. As a best practice, do not exclude any ports except for the ports used for
Telnet and MAD to avoid incorrect traffic forwarding.
The ports that have been shut down by MAD come up when the member devices reboot to join the
recovered IRF fabric. If auto recovery fails because the current master fails or any other exception
occurs, use the mad restore command to manually recover the member devices and bring up the
ports.
Examples
# Exclude Ten-GigabitEthernet 1/0/1 from being shut down when the MAD status transits to
Recovery.
