Choose the menu QoS→DiffServ→802.1P Priority to load the following page. Figure 11-8 802.1P Priority The following entries are displayed on this screen: Priority and CoS-mapping Config Select: Tag-id/CoS-id: Queue TC-id: Select the desired 802.1P tag-id/cos-id for 802.1P priority configuration. It is multi-optional. Indicates the precedence level defined by IEEE 802.1P and the CoS ID. Indicates the priority level of egress queue the packets with tag and CoS-id are mapped to. The priority levels of egress queue are labeled as TC0, TC1, TC2 ...TC7. Note: To complete QoS function configuration, you have to go to the Schedule Mode page to select a schedule mode after the configuration is finished on this page. Configuration Procedure: Step Operation Description 1 Configure the mapping Required. On QoS→DiffServ→802.1P Priority page, relation between the 802.1P configure the mapping relation between the 802.1P priority Tag/CoS and the TC priority Tag/CoS and the TC. 2 Select a schedule mode Required. On QoS→DiffServ→Schedule Mode page, select a schedule mode. 11.1.4 DSCP Priority On this page you can configure DSCP priority. DSCP (DiffServ Code Point) is a new definition to IP ToS field given by IEEE. This field is used to divide IP datagram into 64 priorities. When DSCP Priority is enabled, IP datagram are mapped to different priority levels based on DSCP priority mode; non-IP datagram with 802.1Q tag are mapped to different priority levels based on 802.1P priority mode if 8021.1P Priority mode is enabled; the untagged non-IP datagram are mapped based on port priority mode. 165
