priority-tagged frames are forwarded with port default
QoS value configured. When this mode is selected, the
Default PCP and Default DEI fields are shown, allowing
user to configure PCP and DEI values to be used in all
forwarded frames. Possible configurations are as follows:

Default PCP : indicates which PCP value must be
attached to all egressing frames. Allowed values
are the PCP bits range values, from 0 to 7;

Default DEI : indicates which DEI value must be
attached to all egressing frames. Allowed values
are the DEI bits range values, 0 or 1.
 Mapped : indicates port behaviour as mapped QoS tag
remarking. In this mode, egressing untagged, tagged and
priority-tagged frames are forwarded with QoS value
configured. Each PCP value and DEI value embedded can
be mapped to a specific PCP to egress process
independently. When this mode is selected, the (QoS
Class, DP level) to (PCP, DEI) mapping table is shown,
allowing user to configure PCP and DEI values to be used
in all forwarded frames per queue. Possible configurations
are as follows:

QoS class : shows the QoS queue to be
configured at this row;

DP level : shows the DP level to be configured at
this row;

PCP : indicates which PCP value must be
attached to frames with QoS class (PCP bits) and
DP level shown in the QoS class and DP level
columns. That is, a given PCP frame with a given
DP level should be remarked at egressing
process to the PCP value configured in this field.
Allowed values are the PCP bits range values,
from 0 to 7;

Default DEI : indicates which DEI value must be
attached to frames with QoS class (PCP bits) and
DP level shown in the QoS class and DP level
columns. That is, a given PCP frame with a given
DP level should be remarked at egressing
process to the DEI value configured in this field.
Allowed values are the DEI bits range values, 0 or
1.

If one configuration is desired to be applied at all ports, then the row “*” should be
used, that is, configuration done in the “*” row will be replied to all ports. Possible
configurations are as follows.
After one of the configurations described before is changed, there are buttons that
allow the user to save or discard the configurations and to cancel the menu.
