DSCP Trust Settings
This page is to configure the DSCP trust state of ports. When ports are under the DSCP trust mode, the switch will

The fields that can be configured are described below:

DSCP Map Settings
The mapping of DSCP to queue will be used to determine the priority of the packet (which will be then used to
determine the scheduling queue) when the port is in DSCP trust state.
The DSCP-to-DSCP mapping is used in the swap of DSCP of the packet when the packet is ingresses to the port. The
remaining processing of the packet will base on the new DSCP. By default, the DSCP is mapped to the same DSCP.
To view the following window, click QoS > DSCP > DSCP Map Settings, as shown below:
