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 and the frame is tagged, then the frame is classified to
a CoS that is based on the PCP value in the tag as shown below. Otherwise the
frame is classified to the default CoS.
PCP value: 0 1 2 3 4 5 6 7
CoS value: 1 0 2 3 4 5 6 7
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 and the frame is tagged, then the frame is classified to
a DPL that is equal to the DEI value in the tag. Otherwise the frame is classified
to the default DPL. The classified DPL can be overruled by a QCL entry
