Information
When an error is detected on an SFM module, this command is a manual recovery mechanism. Since
this command can be used with live traffic running, the switch fabric will not go down if the switch
fabric is in an UP state. When there is a full set of SFMs online in the chassis, resetting one SFM will
reduce the total bandwidth supported by the chassis and may affect data flow. A warning message is
issued at the command line and requires user confirmation to proceed (refer to Example 1 below).
Example 1 FTOS#reset sfm 0
SFM0 is active. Resetting it might temporarily impact data traffic.
Proceed with reset [confirm yes/no]:yes

FTOS#
This command does not permit resetting any SFM when the system has (max-1) SFM and switch fabric
is up (refer to Example 2 below).
Example 2 FTOS#reset sfm 1
% Error: SFM1 is active. Resetting it will impact data traffic.
