9.1.3 802.1P/CoS mapping

On this page you can configure the mapping relation between the 802.1P priority tag-id/CoS-id and
the TC-id.
802.1P gives the Pri field in 802.1Q tag a recommended definition. This field, ranging from 0-7, is
used to divide packets into 8 priorities. 802.1P Priority is enabled by default, so the packets with
802.1Q tag are mapped to different priority levels based on 802.1P priority mode but the untagged
packets are mapped based on port priority mode. With the same value, the 802.1P priority tag and
the CoS will be mapped to the same TC.
Choose the menu QoS→DiffServ→802.1P/CoS mapping to load the following page.
Select Enable or Disable DSCP Priority.
