Parameter
cos-id —— The priority of port. It ranges from 0 to 7, which represent
CoS0-CoS7 respectively. By default, the priority is 0.
Command Mode
Interface Configuration Mode (interface gigabitEthernet / interface range
gigabitEthernet)
User Guidelines
Port priority is one property of the port. When the port priority is specified, the
data will be classified into the egress queue based on the CoS value of the
ingress port and the mapping relation between the CoS and TC in IEEE 802.1P.
Example
Configure the priority of port 5 as 3:
TL-SG2424(config)# interface gigabitEthernet 1/0/5
TL-SG2424(config-if)# qos 3
qos cos
This command is supported only on TL-SG2210P/TL-SG2452.
Description
The qos cos command is used to enable the mapping relation between
IEEE802.1P Priority and TC egress queue. To disable the mapping relation,
please use no qos cos command.
Syntax
qos cos
no qos cos
Command Mode
Global Configuration Mode
User Guidelines
IEEE 802.1P gives the Pri field in IEEE 802.1Q tag a recommended definition.
When the mapping relation between IEEE 802.1P Priority and TC egress queue
is enabled, the data will be classified into the egress queue based on this
mapping relation.
