mad exclude interface

Use mad exclude interface to exclude a service 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 a service 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 service interfaces automatically excluded by the system, all service interfaces are shut down when the IRF fabric transits to the Recovery state. The system automatically excludes the following service 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.

Parameters

interface-type interface-number: Specifies a service interface by its type and number.

Usage guidelines

If a service interface must be kept in up state for special purposes such as Telnet connection, exclude the service interface from the shutdown action. As a best practice to avoid incorrect traffic forwarding, do not exclude any service interfaces except for the interfaces used for Telnet.

The service 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 service interfaces that were shut down by MAD.
