QoS > DSCP Priority Settings
When using the DSCP priority mechanism, the packet is classified based on the DSCP field in the IP header.
If the tag is present, the packet is assigned to a programmable egress queue based on the value of the
tagged priority. The tagged priority can be designated to any of the available queues. When a packet is
received containing this DSCP tag, it will be mapped to the CoS queue configured here. These settings will
only take effect if at least one of the priority settings per port is configured for DSCP. When DSCP is set to
enable, TOS cannot be used, and when TOS is set to enable, DSCP cannot be used.

QoS > Priority Settings
The Priority Setting page allow users to configure the CoS priority settings on a port or ports. When CoS
tagged packets arrive on the switch, they are mapped to the settings configured here. For example, if a port
has been assigned a MAC priority, the packet that has the CoS priority assigned to a MAC address will be
sent to the CoS queue configured for that MAC address. Once the configuration has been completed, users
may see the results in the Priority Settings Table seen here. After configuring the port priorities, users may
adjust the individual CoS settings on the other windows located in the CoS folder of the Switch.
