Configuring QoS Class of Service Configuration
Step 1 configure
Enter global configuration mode
Step 2 interface {fastEthernet
port
| range fastEthernet
port-list
| gigabitEthernet
port
| range
gigabitEthernet
port-list
| ten-gigabitEthernet
port
| range ten-gigabitEthernet
port-list

port-channel
port-channel-id
| range port-channel
port-channel-list
}
Enter interface configuration mode.
Step 3 qos trust mode {
untrust
|
dot1p
|
dscp
}
Select the trust mode for the port. By default, it is untrust. Here we set the trust mode as
untrust.
untrust:
Specify the ports’ trust mode as untrust. In this mode, the packets will be processed
according to the port priority configuration.
Step 4 qos port-priority {
dot1p-priority
}
Specify the port to 802.1p priority mapping for the desired port. The ingress packets from
one port are first mapped to 802.1p priority based on the port to 802.1p mapping, then to TC
queues based on the 802.1p to queue mapping. The untagged packets from one port will be
added an 802.1p priority value according to the port to 802.1p mapping.
dot1p-priority:
Specify the 802.1p priority ranging from 0 to 7. The default value is 0.
Step 5 show qos trust interface [fastEthernet
port
| gigabitEthernet
port
| ten-gigabitEthernet
port
| port-channel
port-channel-id
]
Verify the trust mode of the ports.
Step 6 show qos port-priority interface [fastEthernet
port
| gigabitEthernet
port
| ten-
gigabitEthernet
port
| port-channel
port-channel-id
]
Verify the port to 802.1p mappings.
Step 7 end
Return to privileged EXEC mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
