QoS Configuration 365You should first define an ACL before this configuration task.The granularity of traffic limit is 64kbps. If the target-rate user input is in ( N*64,(N+1)*64], in which N is a natural number, Switch automaticaly sets (N+1)*64 as theparameter value.This configuration achieves rate control for those packets that match the ACL. If thetraffic rate threshold is exceeded, corresponding measures will be taken, for example,dropping excessive packets.Setting Line Limit Line limit refers to rate limit based on the port, that is, limiting the total rate at theport. The granularity of line rate is 64 kbps.Perform the following configurations in the Ethernet Port View.Table 383 Setting Line RateRelabeling Priority Level This configuration re-labels priority level for the packets that match ACL. The newpriority label can be put in the priority domain in the header.Perform the following configurations in the Ethernet Port View.Table 384 Relabeling Priority LevelConfiguring TrafficStatisticsThe traffic statistics function is used for counting the data packets of the specifiedtraffic, that is, this function counts the transmitted data which matches the ACL rules.After the traffic statistics function is configured, the user can use displayqos-interface traffic-statistic command to display the statistics information.You can use the following command to configure traffic statistics.Perform the following configuration in the Ethernet Port View.Remove trafficlimitundo traffic-limit inbound { user-group acl_number [rule rule ] | ip-group acl-number [ rule rule [ link-groupacl_number rule rule ] ] | link-group acl_number [ rulerule ] }Operation CommandOperation CommandSet line limit line-rate { inbound | outbound } target_rateRemove line limit undo line-rate{ inbound | outbound }Operation CommandRelabel traffic priority traffic-priority { inbound | outbound } { user-groupacl-number [ rule rule ] | ip-group acl_number [ rulerule [ link-group acl_number rule rule ] ] |link-group acl_number [ rule rule ] } { { dscpdscp_value | ip-precedence { pre_value | from-cos }} | cos { pre_value | from-ipprec } | local-precedencepre_value }*Remove the setting undo traffic-priority { inbound | outbound } {user-group acl_number [ rule rule ] | ip-groupacl-number [ rule rule [ link-group acl_number rulerule ] ] | link-group acl_number [ rule rule ] }
