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
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.
