Parameters
interface-type interface-number: Specifies a port by its type and number.
Usage guidelines
MAD action is not configurable for IRF physical ports.
When MAD detects that an IRF fabric has split into two or more identical active IRF fabrics, it sets one of
the IRF fabrics to the Detect state and all other IRF fabrics to the Recovery state.
The Detect-state IRF fabric is active and can continue to forward traffic.
•
The Recovery-state IRF fabrics are inactive. MAD shuts down all their physical ports except the
•
physical IRF ports and the ports manually configured to not shut down.
If a port must be kept in up state for special purposes such as Telnet connection, exclude the port from
the shutdown action. To avoid incorrect traffic forwarding, HP recommends not excluding any ports
except the ports used for Telnet and MAD.
The ports that have 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 FortyGigE 2/0/5/1 from being shut down when the MAD status transits to Recovery.

[Sysname] mad exclude interface fortygige 2/0/5/1
