TOS Priority Settings

When using the TOS/DSCP priority mechanism, the packet is classified based on the TOS/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 TOS is set to enable, DSCP cannot be used, and when DSCP is set to
enable, TOS cannot be used.
TOS Priority Settings can be specified on this window. Use the drop-down menus to select a value for TOS and Class ID.
