Port DSCP

Port DSCP menu allows enabling DSCP QoS function and basic configuration. At this
menu it is possible to enable if DSCP will be used as quality of service mechanism
and define basic behaviour of its usage. Possible configurations are as follows.
Port: shows the port to be configured at this row;
o
Translate: indicates if ingress translation should be used by this
o
port. This checkbox is used together with the Classify field to define
the ingress rules of the DSCP function. Checkbox selected means
ingress translation enabled, and checkbox empty means disabled;
Classify: indicates how should be executed DSCP ingress
o
classification. Possible configuration is as follows:




Egress: indicates how should be executed DSCP egress rewriting
o
process. Possible configuration is as follows:


Save: save configuration at the Running Config;

Reset: undo changes made locally at the
Running Config;

Cancel: cancel changes made locally and return
to previous page.
Disable: indicates that no ingress DSCP is used. This
means that DSCP analysis for QoS function is disabled at
the port;
DSCP=0: indicates that only frames with DSCP bits equal 0
should be classified. DSCP-to-QoS Class classification will
be as configured at the DSCP Classification;
Selected: indicates that only frames with DSCP bits
marked should be classified. If selected, the DSCP
Translation menu should be used to select which DSCP
levels should be classified;
All: indicates that all frames with DSCP bits will be
classified. If selected, all frames will be classified to a
DSCP queue.
Disable: indicates that no egress DSCP rewriting is used.
This means that DSCP bits of a given incoming frame will
be discarded at the egress process;
Enable: indicates that egress DSCP rewriting is used, but
there is no remap of the DSCP bits. This means that DSCP
bits of a given incoming frame will be maintained at the
egress process;
