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.
