4.1.19 Configuration - QoS
4.1.19.1 QoS - Port Classification
This page allows you to configure the basic QoS Ingress Classification settings
for all switch ports.
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.
