Parameter description:
 Port :
The port number for which the configuration below applies.
 CoS :
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.
 DPL :
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.
 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 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
