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} {pri} no qos dot1p config Parameter tag -- The 8 priority levels defined by IEEE 802.1P, ranging from 0 to 7. pri -- The priority level 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 value, the higher p r i o r i t y. Example Map tag value 0 to TC3: TP-LINK(config)# qos dot1p config 0 3 qos dscp enable Description The qos dscp enable command is used to enable the mapping relation between DSCP Priority and Egress Queue. To disable the mapping relation, please use no qos dscp enable command. Syntax qos dscp enable no qos dscp enable Command Mode Global Configuration Mode Example Enable the mapping relation between DSCP Priority and Egress Queue: 63

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
} {
pri
}
no qos dot1p config
Parameter
tag
——
The 8 priority levels defined by IEEE 802.1P, ranging from 0 to 7.
pri
——
The priority level 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 value, the higher
priority.
Example
Map tag value 0 to TC3:
TP-LINK(config)#
qos dot1p config
0
