TP-Link TL-SG2216 User Manual

DSCP: Indicates the
priority determined by the DS region of IP datagram.
It ranges from 0 to 63.
Priority: Indicates the 802.1P priority the packets with tag are mapped to.
The priorities are labeled as CoS0 ~ CoS7.
Configuration Procedure:
Step Operation Description
1 Configure the mapping
relation between the DSCP
priority and 802.1P priority
Required. On QoS→DiffServ→DSCP Priority page,
enable DSCP Priority and configure the mapping
relation between the DSCP priority and CoS.
2 Configure the mapping
relation between the CoS and
the TC
Required. On QoS→DiffServ→802.1P/CoS mapping
page, configure the mapping relation between the CoS
and the TC.
3 Select a schedule mode Required. On QoS→DiffServ→Schedule Mode
page, select a schedule mode.
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.
Figure 9-8 802.1P/CoS mapping

:
 Priority and CoS-mapping Config
Tag-id/Cos-id: Indicates the precedence level defined by IEEE802.1P and the
CoS ID.
