Purpose
Sets the time interval for the PFC QoS statistics data
export.
The interval needs to be short enough to avoid
Note
counter wraparound with the activity in your

be careful when decreasing the interval.
Reverts to the default time interval for the PFC QoS
statistics data export.
Exits configuration mode.
Verifies the configuration.
