Example
Enable the mapping relation between IEEE 802.1P Priority and Egress Queue:
TP-LINK(config)# qos dot1p enable
qos dot1p config
Description
The qos dot1p config command is used to configure the mapping relation
between IEEE 802.1P Priority and Egress Queue. To return to the default
configuration, please use no qos dot1p config command. IEEE 802.1P gives
the Pri field in IEEE 802.1Q tag a recommended definition. This field is used to
divide packets into 8 priorities. When IEEE 802.1P Priority is enabled, the
packets with IEEE 802.1Q tag are mapped to different priority levels based on
IEEE 802.1P priority mode. The untagged packets are mapped based on port
priority mode.
Syntax
qos dot1p config {tag} {tc-id}
no qos dot1p config
Parameter
tag —— The 8 priority levels defined by IEEE 802.1P, ranging from 0 to 7.
tc-id —— The egress queue the packets with tag are mapped to. It ranges from
0 to 3, which represent TC0, TC1, TC2, TC3 respectively.
Command Mode
Global Configuration Mode
User Guidelines
1. By default, the mapping relation between tag and the egress queue is:
0-TC1, 1-TC0, 2-TC0, 3-TC1, 4-TC2, 5-TC2, 6-TC3, 7-TC3
2. Among the priority levels TC0-TC3, the bigger the value, the
higher the priority.
