PCP
Controls the default Priority Code Point (PCP).
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.
DEI
Controls the default Drop Eligible Indicator
(DEI) for untagged frames. 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.
Tag Class
Shows the classification mode for tagged frames on this port.
Disabled: Use the default QoS class and DP level for tagged
frames.
Enabled: Use the 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 QoS class and DP level.

because voice video usually maintains a steady rate of traffic.
