Description
The port number for which the configuration below applies.
Controls the default class of service. All frames are classified to a CoS. There is a one to one
mapping between CoS, queue and priority. A CoS of 0 (zero) has the lowest priority. If the port
is VLAN aware, the frame is tagged and Tag Class is enabled, then the frame is classified to
a CoS that is mapped from the PCP and DEI value in the tag. Otherwise the frame is
classified to the default CoS. The classified CoS can be overruled by a QCL entry.
NOTE: If the default CoS has been dynamically changed, then the actual default CoS is
shown in parentheses after the configured default CoS.
Controls the default drop precedence level. All frames are classified to a drop precedence
level. If the port is VLAN aware, the frame is tagged and Tag Class is enabled, then the frame
is classified to a DPL that is mapped from the PCP and DEI value in the tag. Otherwise the
frame is classified to the default DPL. The classified DPL can be overruled by a QCL entry.
Controls the default PCP value. All frames are classified to a PCP value. If the port is VLAN
aware and the frame is tagged, then the frame is classified to the PCP value in the tag.
Otherwise the frame is classified to the default PCP value.
Controls the default DEI value. All frames are classified to a DEI value. If the port is VLAN
aware and the frame is tagged, then the frame is classified to the DEI value in the tag.
Otherwise the frame is classified to the default DEI value.
Shows the classification mode for tagged frames on this port. Disabled: Use default QoS class
and DP level for tagged frames. Enabled: Use mapped versions of PCP and DEI for tagged
frames. Click on the mode in order to configure the mode and/or mapping.
NOTE: This setting has no effect if the port is VLAN unaware. Tagged frames received on
VLAN unaware ports are always classified to the default CoS and DPL.
Click to Enable DSCP based QoS Ingress Port Classification.
The IP/MAC address mode specifying whether the QCL classification must be based on
