Command Reference Guide
qos
Use the qos (quality of service) command to set the interface to the trusted state and to set the default cost
of service (CoS) value. To return to defaults, use the no form of this command. Variations of this
command include:
qos default-cos <value>
qos trust cos
Syntax Description
default-cos <value>
trust cos
Default Values
By default, the interface is untrusted with a default CoS of 0.
Command History
Release 5.1
Functional Notes
Set the interface to trust cos if received 802.1P. CoS values are considered valid (i.e., no need to
reclassify) and do not need to be tagged with the default value. When set to untrusted, the default-cos
value for the interface is used.
Usage Examples
The following example sets Ethernet interface 0/1 as a trusted interface and assigns untagged packets a
CoS value of 1:
(config)#interface ethernet 0/1
(config-eth 0/1)#qos trust cos
(config-eth 0/1)#qos default-cos 1
60000CRG0-35E
Sets the default CoS value for untrusted ports and all untagged packets.
