mad exclude interface
Use mad exclude interface to exclude an interface 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 an interface 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
Except for the network interfaces automatically excluded by the system, all network interfaces are
shut down when the IRF fabric transits to the Recovery state. The system automatically excludes the
following network interfaces from being shut down:
IRF physical interfaces.
Interfaces used for BFD MAD.
Member interfaces of an aggregate interface if the aggregate interface is excluded from being
shut down.
Views
System view
Predefined user roles
network-admin
Parameters
interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
If an interface must be kept in up state for special purposes such as Telnet connection, exclude the
interface from the shutdown action. As a best practice to avoid incorrect traffic forwarding, do not
exclude any interfaces except the interfaces used for Telnet.
The interfaces that have been shut down by MAD come up when the member devices reboot to join
the recovered IRF fabric. If the active IRF fabric fails before the IRF link is recovered, use the
mad
restore
command on the inactive IRF fabric to recover the inactive IRF fabric. This command also
brings up all interfaces that were shut down by MAD.
Examples
# Exclude Ten-GigabitEthernet 1/0/1 from being shut down when the MAD status transits to
Recovery.

[Sysname] mad exclude interface ten-gigabitethernet 1/0/1
