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, only the
IRF fabric whose master has the lowest member ID among all the masters can still forward data
traffic. MAD changes its status to Recovery on all the other IRF fabrics and shuts down all their
physical ports except the physical IRF ports and those manually configured to not shut down.
If a port must be kept in up state for special purposes such as Telnet connection, exclude it from
the shutdown action. To avoid problems, HP recommends excluding only the one used for Telnet
for the management purpose.
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.
