Configuring Traffic Statistics

The traffic statistics function counts the transmitted data that matches the ACL rules. After the traffic statistics function is configured, you can use the display qos-infotraffic-statisticcommand to display the statistics information.

Perform the following configuration in QoS view.

Table 183 Configuring Traffic Statistics

Operation	Command
Configure traffic statistics	traffic-statistic { inbound outbound } {
	ip-group{ acl-number acl-name } [ rule rule
	] link-group{ acl-number acl-name } [ rule
	rule ] }
Cancel the traffic statistics configuration	undo traffic-statistic { inbound
	outbound } { ip-group { acl-number
	acl-name} [ rule rule ] link-group {
	acl-number acl-name } [ rule rule ] }
Display the statistics information	display qos-info traffic-statistic [
	interface-name interface-type
	interface-num ] traffic-statistic

For details about the command, see the Switch 7750 Command Reference Guide.

Displaying and Debugging QoS

After you configure QoS, execute the display command in all views to display the QoS configuration, and to verify the effect of the configuration. Execute the reset command in user view to clear the statistics of the QoS module.
