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 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.
