The

Port Classification
menu path displays the QoS Ingress Port Classification
page. This page lets you configure the basic QoS Ingress Classification settings for all switch ports.
The displayed Port Classification settings are explained below.
Port
The port number for which the configuration below applies.
CoS
Controls the default class of service (
0
-
7
). 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 (default).
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.
