
o
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.
Save: save configuration at the Running Config;
o
Reset: undo changes made locally at the Running Config.

DSCP-Based QoS menu allows enabling DSCP QoS based on a DSCP-to-QoS Class
mapping. At this menu it is possible to map each DSCP value to a given QoS Class
queue and DPL levels. Possible configurations are as follows.
DSCP: shows the DSCP level to be configured at this row;
o
Trust: indicates if DSCP value is trusted, and thus can be remapped
o
to the QoS Class and DPL configured. Only trusted DSCP levels are
remapped as configured to the QoS Class and DPL columns.
Untrusted DSCP frames are treated as non-IP frame by the switch.
Checkbox selected means DSCP level trusted, and checkbox empty
means untrusted;
QoS Class: indicates to which QoS Class queue the DSCP level
o
frame should be remapped. Each DSCP value can be configured to
the requested QoS Class queue independently. Allowed values are
the PCP bits range values, from 0 to 7;
DPL: indicates to which DPL level rule the DSCP level frame should
o
be remapped. Each DSCP value can be configured to the requested
DPL level independently. Allowed values are the DPL allowed range
values, from 0 to 3.
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.
Save: save configuration at the Running Config;
o
Reset: undo changes made locally at the Running Config.
o
Remap: indicates that egress DSCP rewriting is used and
DSCP bits will be remapped to the values configured at
the DSCP Translation menu. This means that DSCP bits of
a given incoming frame will be changed as configured by
user at the egress process.
