Setting the PFC QoS Statistics Data Export Time Interval

To set the time interval for the PFC QoS statistics data export, perform this task:

Command

Purpose

Step 1

Router(config)# mls qos statistics-export

interval

interval_in_seconds

Sets the time interval for the PFC QoS statistics data
export.

Note

The interval needs to be short enough to avoid
counter wraparound with the activity in your
configuration, but because exporting PFC QoS
statistic creates a significant load on the switch,
be careful when decreasing the interval.

Router(config)# no mls qos statistics-export

interval

interval_in_seconds

Reverts to the default time interval for the PFC QoS
statistics data export.

Step 2

Router(config)# end

Exits configuration mode.

Step 3

Router# show mls qos statistics-export info

Verifies the configuration.
