Basic Mode Page
The
Basic Mode Page contains the following fields:
• Trust Mode — Displays the trust mode. If a packet’s CoS tag and DSCP tag, are
mapped to different queues, the Trust Mode determines the queue to which
the packet is assigned. Possible values are:
- CoS — Sets trust mode to CoS on the device. The CoS mapping
determines the packet queue
- DSCP — Sets trust mode to DSCP on the device. The DSCP mapping
determines the packet queue.
• Always Rewrite DSCP — Rewrites the packet DSCP tag according to the QoS
DSCP Rewriting configuration.
Always Rewrite DSCP can only be selected if
the Trust Mode is set to
DSCP .
Rewriting DSCP Values
In the DSCP Mapping Page , define the Differentiated Services Code Point
(DSCP) tag to use in place of the incoming DSCP tags.
