Configuring CoS-Based Packet Statistics
Configuring CoS-Based Packet Statistics
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.
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 11-8 in EXEC mode.
Example 11-16 shows examples of these commands.

Table 11-7 CoS-Based Packet Statistics Command
Command Purpose
ML_Series(config-if)# cos
accounting
Enables CoS-based packet statistics to be recorded at the specific
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.
