The Basic Mode Page opens: 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.
