QoS (Quality of Service) function is used to optimize the network performance. It provides you with 

network service experience of a better quality. 

The qos command is used to configure CoS (Class of Service) based on port. 

To return to the default configuration, please use no qos command. 

qos cos-id 

cos-id  — —  The priority of port. It ranges from 0 to 7, which represent 

CoS0-CoS7 respectively. By default, the priority is 0. 

Interface Configuration Mode (interface gigabitEthernet / interface range 

gigabitEthernet) 

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. 

Configure the priority of port 5 as 3: 

TL-SG3424(config)# interface gigabitEthernet 1/0/5 

TL-SG3424(config-if)# qos 3 

The qos dscp command is used to enable the mapping relation between DSCP 

Priority and CoS value. To disable the mapping relation, please use no qos 

dscp command.
