By default, the priority is 0. Command Mode Interface Configuration Mode (interface fastEthernet / interface range fastEthernet / 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: T2500-28TC(config)#interface fastEthernet 1/0/5 T2500-28TC(config-if)#qos 3 qos cos 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. 164

Chapter 25 QoS Commands
QoS (Quality of Service) function is used to optimize the network performance. It provides you with
network service experience of a better quality.
qos
Description
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.
Syntax
qos
cos-id
no qos
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)
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:
T2500-28TC(config)#interface fastEthernet
1/0/5
T2500-28TC(config-if)#qos
3
qos cos
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.
