3.5.47 Main Menu->QoS->Policy Config.
Differentiated Service (DiffServ) uses a priority tag in the data packet (the Differentiated Service Code
Point or DSCP) to determine the priority of the packet. The Policy Config menu maps the various
DSCP tags to the two four queues on each port. The Classifier allows users to add different rules to
distinguish traffic service. An administrator is able to classifier based on Protocol, Source MAC
Address, Source IP Address, Destination MAC Address, Destination IP Address, VLAN ID, DSCP,
Source Layer 4 Port, and Destination Layer 4 Port.
To create an applicable policy, the administrator configures conditions properly and apply these
conditions to policy by in-profile action or out-profile action, or no-match action.
Symbol recommends remembering those IDs given to Classifier, In Profile Action, No Match Action,
and Out Profile Action. If necessary, the administrator can retrieve the ID associated information from
the Show Each ID Information command.
