mef qos
Use the mef qos command to configure the Metro Ethernet Forum (MEF) Ethernet quality of service
(QoS) parameters. These parameters specify the hardware queues used by the Ethernet virtual connection
(EVC) when traffic matching an EVC map is discovered, as well as the Metro Ethernet network (MEN)
priority given to untagged traffic. Using the no form of this command returns the MEF QoS settings to the
default values. Variations of this command include:
mef qos cos-map <number> <value>
mef qos untagged <value>
Syntax Description
cos-map <number> <value> Specifies default mapping of queues to class of service (CoS) markings for
untagged <value>
Default Values
By default, a MEN priority of 0 is assigned to untagged traffic.
The default MEF QoS queue assignments are outlined below.
