Configuring CoS-Based Packet Statistics

Chapter 11 Configuring Quality of Service on the ML-Series Card

Note For IEEE 802.1Q (QinQ) enabled interfaces, CoS accounting is based only on the CoS value of the outer metro tag imposed by the service provider. The CoS value inside the packet sent by the customer network is not considered for CoS accounting.

To enable CoS-based packet statistics on an interface, use the interface configuration level command defined in Table 11-7.

Table 11-7 CoS-Based Packet Statistics Command

Command	Purpose

ML_Series(config-if)# cos	Enables CoS-based packet statistics to be recorded at the specific
accounting	interface and for all the subinterfaces of that interface. This
	command is supported only in interface configuration mode and not
	subinterface configuration mode.
	The no form of the command disables the statistics.

After configuring CoS-based packet statistics on the ML-Series card, the statistics can be viewed through a variety of show commands. To display this information, use one of the commands in Table 11-8in EXEC mode.

Table 11-8 Commands for CoS-Based Packet Statistics

Command	Purpose

ML_Series# show interface type number	Displays the CoS-based packet statistics available for
cos	an interface.

ML_Series# show interface type	Displays the CoS-based packet statistics available for
number.subinterface-number cos	a FastEthernet subinterface. POS subinterfaces are not
	eligible.

Example 11-16shows examples of these commands.
