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 fastEthernet / interface range
fastEthernet / interface gigabitEthernet / interface range gigabitEthernet/
interface ten-gigabitEthernet / interface range ten-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:
T2700G-28TQ(config)#interface gigabitEthernet
1/0/5
T2700G-28TQ(config-if)#qos
