Usage
Information
When you insert or remove a secondary RPM with logical SFM, the system must
add or remove the backplane links to the switch fabric trunk. To avoid traffic
disruption, use this command when you insert the secondary RPM. When you
execute this command, the logical SFM on the standby RPM is immediately taken
offline and the SFM state is set as “standby”.
NOTE: This command could affect traffic when taking the secondary SFM
offline.
