Dscp; Untagged And Priority Tagged Frames; Men-Pri; Men-Queue - ADTRAN Total Access 5000 Deployment Manual

DSCP

This attribute is the DSCP value of the Ethernet frame received at the UNI port. This attribute
can only be specified if the CE‐VLAN P‐bit attribute is not specified.

Untagged and Priority Tagged Frames

This attribute controls whether untagged and priority tagged frames are allowed to ingress
the UNI port in addition to frames tagged with the specified CE‐VLAN‐ID. Table F‐8 lists the
available options.
Option
Enabled
Disabled
A priority tag is a frame that is tagged with a CE VLAN ID of zero. If the untagged attribute is
specified with no other attributes except the UNI port, then the EVC map only forwards
untagged and priority tagged frames to the EVC. If other attributes are specified for the EVC
map in addition to the untagged attribute, then the untagged and priority tagged attribute
indicates that untagged and priority tagged frames are forwarded to the EVC in addition to
the frames that are characterized by the other EVC map attributes.

MEN-Pri

This attribute controls how frames classified by the EVC map populate the p‐bit of the s‐tag
added by the EVC. This attribute can be explicitly set to a priority value in the range of 0 to 7
or it can be set to inherit. If this attribute is set to inherit, the top VLAN tag p‐bit value of the
classified frames is used to populate the EVC s‐tag p‐bit field. If the classified frame does not
contain a VLAN tag, the p‐bit value used can be derived from a system level setting. If the
attribute is explicity set to a value, all classified frames by the EVC map add the EVC service
tag with a p‐bit equal to the explicity configured value.

Men-Queue

This attribute controls how frames admitted by the EVC map are mapped to queues. If the
MEN queue attribute is explicity set, the traffic enters the desired queue regardless of the
system level provisioned p‐bit to queue mapping from the network element. When set to
inherit, it follows the system level provisioned mapping.
The CoS mapping can be changed from the default 802.1Q‐2005 mapping by using the qos
cos‐map <queue> <class> command.

Policer

This attribute displays the policer, if any, that is applied to the EVC map.
