Understanding PFC QoS Statistics Data Export

Note •
•
The PFC QoS statistics data export feature generates per-LAN-port and per-aggregate policer utilization
information and forwards this information in UDP packets to traffic monitoring, planning, or accounting
applications. You can enable PFC QoS statistics data export on a per-LAN-port or on a per-aggregate
policer basis. The statistics data generated per port consists of counts of the input and output packets and
bytes. The aggregate policer statistics consist of counts of allowed packets and counts of packets
exceeding the policed rate.
The PFC QoS statistics data collection occurs periodically at a fixed interval, but you can configure the
interval at which the data is exported. PFC QoS statistics collection is enabled by default, and the data
export feature is disabled by default for all ports and all aggregate policers configured on the
Catalyst 6500 series switch.

The PFC QoS statistics data export feature is completely separate from NetFlow Data Export and
does not interact with it.
The PFC QoS statistics data export feature supports the PFC QoS features described in
"Configuring PFC QoS," that are implemented in the port ASICs and the PFC3B.
