JetStream 52-Port Gigabit Stackable L3 Managed Switch CLI Guide
24.2 classofservice priority
Description
The classofservice priority command is used to configure CoS (Class of
Service) based on port. To return to the default configuration, please use no
classofservice priority command.
Syntax
classofservice priority
cos-id
no classofservice priority
Parameter
cos-id
āā 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
802.1p/CoS mapping.
Example
Configure the priority of port 5 as 3:
T3700G-52TQ(config)#interface gigabitEthernet 1/0/5
T3700G-52TQ(config-if)#classofservice priority 3
24.3 classofservice queue cos-map
Description
The classofservice queue cos-map command is used to configure the
mapping relation between IEEE 802.1p priority tag/IEEE 802.1Q tag, CoS
value and the TC egress queue. To return to the default configuration, please
use no classofservice queue cos-map command. When 802.1p Priority is
enabled, the packets with 802.1Q tag are mapped to different priority levels
