Understanding CoS-Based Packet Statistics

Enhanced performance monitoring displays per-CoS packet statistics on the ML-Series card interfaces
when CoS accounting is enabled. Per-CoS packet statistics are only supported for bridged services, not
for IP routing or Multiprotocol Label Switching (MPLS). CoS-based traffic utilization is displayed at
the Fast Ethernet or Gigabit Ethernet interface or subinterface (VLAN) level, or at the POS interface
level. It is not displayed at the POS subinterface level. Cisco proprietary RPR statistics are not available
at the SPR interface level, but statistics are available for the individual POS ports that make up the SPR
interface. EtherChannel (port-channel) and BVI statistics are available only at the member port level.

1. Drop counts only include discards caused by output congestion and are counted at the output interface.
CoS-based packet statistics are available through the Cisco IOS CLI and Simple Network Management
Protocol (SNMP), using an extension of the CISCO-PORT-QOS MIB. They are not available through
CTC.

Configuring CoS-Based Packet Statistics

CoS-based packet statistics require the enhanced microcode image to be loaded onto the ML-Series card.
