Chapter 32 Configuring PFC QoS
Configuring PFC QoS
• For data from a VLAN interface:
– Export type (“5” for a class map and VLAN)
– Class map name
– Direction (“in”)
– PFC or DFC slot number
– VLAN ID
– Number of in-profile packets
– Number of packets that exceed the CIR
– Number of packets that exceed the PIR
– Time stamp
• For data from a port channel interface:
– Export type (“6” for a class map and port channel)
– Class map name
– Direction (“in”)
– PFC or DFC slot number
– Port channel ID
– Number of in-profile packets
– Number of packets that exceed the CIR
– Number of packets that exceed the PIR
– Time stamp
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 router, 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.
