Unit
: indicates which unit should be used with
Rate value to limit traffic. Allowed values are
kbps, Mbps, fps and kfps.
After one of the configurations described before is changed, there are buttons
that allows the user to save or discard the configurations and to return to the
previous menu.
Save:
save configuration at the Running Config;
Reset
: undo changes made locally at the Running Config;
Back
: undo changes made locally and return to previous
page.
o
Shapers:
shows priority queues and total port shaper values
configured at QoS Egress Port Scheduler and Shapers menu. If
operation of the port is Strict Priority, then the “disable“ word will
be displayed as the shaper value, which means no shaper process
being used. If operation of the port is weighted, then displayed
values are the Rate values configured from each queue and port at
the QoS Egress Port Scheduler and Shapers menu.

Port Tag Remarking
Port Tag Remarking menu allows configuring egress behaviour of frames. Thus, this
menu allows remapping all frames that have priority information at the ingress
process. Ports can be set to not change PCP value at egress of the frame, use only
one defined PCP to all frames or map each QoS queue to a specific PCP value.
Possible configurations are as follows.
o
Port
: indicate the ports to be configured at this row. Port field is a
hyperlink that allows accessing QoS Egress Port Tag Remarking
settings. Port remarking menu allows configuring behaviour of the
port related to frames egressing the port. After clicking Port
number hyperlink, the QoS Egress Port Tag Remarking menu will be
displayed for the port chosen. Tag Remarking mode indicates port
behaviour. Allowed values are Classified, Default and Mapped.
Possible configurations are as follows:
Classified
: indicates port behavior as classified QoS tag
remarking. In this mode, egressing untagged frames are
forwarded with port default QoS value (PCP = 0). Tagged
and priority-tagged frames are forwarded with PCP bits
equal to the PCP bits embedded at the incoming 802.1Q
frame;
Default
: indicates port behavior as default QoS tag
remarking. In this mode, egressing untagged, tagged and
