Usage guidelines
When MAD detects that the 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 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, H3C 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.
Examples
# Exclude Ten-GigabitEthernet 2/0/1 from being shut down when the MAD status transitions to
Recovery.
