Chapter 14 Configuring Quality of Service
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.
For information on the enhanced microcode image, see the “Multiple Microcode Images” section on
page 3-11 .
To enable CoS-based packet statistics on an interface, use the interface configuration level command
defined in
Table 14-7 .
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 14-8 in EXEC mode.
Example 14-19 shows examples of these commands.

Table 14-7 CoS-Based Packet Statistics Command
Command Purpose
Router(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
in subinterface configuration mode.
The no form of the command disables the statistics.

Command Purpose
Router# show interface type number cos Displays the CoS-based packet statistics available for
an interface.
Router# show interface type
number.subinterface-number cos
Displays the CoS-based packet statistics available for
a FastEthernet or Gigabit Ethernet subinterface. POS
subinterfaces are not eligible.
