Figure 10-8

802.1P Priority

The following entries are displayed on this screen:



Priority and CoS-mapping Config

Select: Select the desired 802.1P tag-id/cos-

id for 802.1P priority

configuration. It is multi-optional.

Tag-id/CoS-id:

Indicates the precedence level defined by IEEE 802.1P and the

CoS ID.

Queue TC-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

Configure the mapping

relation between the 802.1P

priority Tag/CoS and the TC

Required. On QoS→DiffServ→802.1P Priority page,

configure the mapping relation between the 802.1P

priority Tag/CoS and the TC.

2 Select a schedule mode Required. On QoS→DiffServ→Schedule Mode page,

select a schedule mode.

10.1.4 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.
