QoS Configuration Commands List 303 undo traffic-priority inbound { ip-group acl-number [ rule rule [ link-group acl-number rule rule ] ] | link-group acl-number [ rule rule ] } View Ethernet Port View Parameter inbound: Performs priority marking to the packets received by the interface. ip-group acl-number: Activates IP ACLs, including basic and advanced ACLs. acl-number : Sequence number of ACL, ranging from 2000 to 3999. link-group acl-number: Activates Layer 2 ACLs. acl-number: Sequence number of ACL, ranging from 4000 to 4999. rule rule: Specifies the subitem of an active ACL, ranging from 0 to 65534; if not specified, all subitems of the ACL will be activated. If only an IP ACL or a Layer 2 ACL is activated, this parameter can be omitted. If both IP and Layer 2 ACLs are activated at the same time, the rule parameter cannot be omitted. dscp dscp-value: Set DSCP priority, ranging from 0 to 63. ip-precedence { pre-value | from-cos }: Set IP precedence, pre-value ranges from 0 to 7. from-cos means to set the IP precedence with the corresponding 802.1p priority value. cos { pre-value | from-ipprec }: Set 802.1p priority. pre-value ranges from 0 to 7. from-ipprec means to set the 802.1p priority of the packet with the corresponding 802.1p priority value. local-precedence: This does not actually remark the packet but gives it an internal "local-precedence" that determines which queue it is assigned to. The queue can be determined by looking at cos-local precedence map using the display qos cos-local-precedence command. Description Use the traffic-priority command to activate an ACL and perform priority marking. Use the undo traffic-priority command to remove the priority marking. The system can mark the packets with various levels DSCP priority, IP Precedence, CoS (802.1p) priority and local Precedence. Related command: display qos-interfacee traffic-priority. Example Perform priority marking to packets that match with the permit rule of ACL 2000. Set its 802.1p priority to 0. system-view System View: return to User View with Ctrl+Z
