Information
When a secondary RPM with logical SFM is inserted or removed, the system must add or
remove the backplane links to the switch fabric trunk. To avoid traffic disruption, use this
command when the secondary RPM is inserted. When this command is executed, the logical
SFM on the standby RPM is immediately taken offline and the SFM state is set as “standby”.
