LASSIFICATION
Use the QoS Ingress Port Classification page to set the basic QoS
parameters for a port, including the default traffic class, DP level (IEEE
802.1p), user priority, drop eligible indicator, classification mode for tagged
frames, and DSCP-based QoS classification.

ARAMETERS
These parameters are displayed:
QoS Ingress Port Classification
◆
Port – Port identifier.
◆
QoS class – Controls the default QoS class, i.e., the QoS class for
frames not classified in any other way. There is a one to one mapping
between QoS class, queue and priority. A QoS class of 0 (zero) has the
lowest priority. (Range: 0-7; Default: 0)
◆
DP level – Controls the default drop priority for frames not classified in
any other way. (Range: 0-1; Default: 0)
◆
PCP – Controls the default Priority Code Point (or User Priority) for
untagged frames. (Range: 0-7; Default: 0)
◆
DEI – Controls the default Drop Eligible Indicator for untagged frames.
(Range: 0-1; Default: 0)
◆
Tag Class. – Shows classification mode for tagged frames on this port:
■
Disabled – Uses the default QoS class and DP level for tagged
frames.
■
Enabled – Uses the mapped versions of PCP and DEI for tagged
frames.
Click on the mode in order to configure the mode and/or mapping.
◆
DSCP Based – Click to Enable DSCP Based QoS Ingress Port
Classification (see page 204 ).
QoS Ingress Port Tag Classification
◆
Tag Classification – Sets classification mode for tagged frames on
this port:
■
Disabled – Uses the default QoS class and DP level for tagged
frames. (This is the default.)
■
Enabled – Uses the mapped versions of PCP and DEI for tagged
frames.
◆
PCP / DEI – Shows the mapping options for classified (PCP, DEI) to
(QoS class, DP level) values when Tag Classification is Enabled.
