Functional Notes
QoS policies are configured in the ADTRAN Operating System (AOS) command line interface (CLI) to
dictate the priority for servicing specified traffic types on a particular interface. QoS policies contain at least
one match reference (using the match command) and one or more action items (using the priority,
bandwidth, shape, or set commands).
The set cos command can be used to change the Ethernet 802.1p priority field for traffic serviced by the
QoS policy. Every 802.1q tagged Ethernet frame contains a 3-bit CoS field used for marking data types
requiring special handling when traveling through the network.
Usage Examples
The following example sets the CoS value, for all matching traffic within the specified QoS map entry, to 1:
(config)#qos map VOICEMAP 10
(config-qos-map)#set cos 1
The following example removes all CoS value change requests from the QoS map entry:
(config)#qos map VOICEMAP 10
(config-qos-map)#no set cos
60000CRG0-35E
Specifies the CoS numeric value. Valid range is 0 to 7.
