Advanced > Traffic Management
Traffic management covers the methods to improve the performance of your network by differentiating traffic and limiting excess broadcast traffic. There are two means to differentiate traffic with this switch- VLAN tags or using Differentiated Service Code Points (DSCP) in the header of data packets. By using either the VLAN tags
Advanced > Traffic Management > Traffic Priority
Port Priority allows the user to specify which ports have greater precedence in situations where traffic may be buffered in the switch due to congestion.
Figure 5-30: Traffic Prioritization Settings
Traffic that comes in on ports with a setting of ‘high’ will be transmitted before those that come in on a port with a ‘normal’ setting. The settings on this page only affect packets that do not already have VLAN priority tags. To raise the priority of a given port, toggle the port’s setting from ‘normal’ to ‘high’. The default setting for a port is ‘normal’.
You may choose to further differentiate packet priority by using the Differentiated Service (DiffServ) feature. DiffServ uses a priority tag in the packet, the Differentiated Service Code Point (DSCP), to determine the priority of the packet. There are 64 different tags available. This menu maps the various DSCP tags to the two queues in the switch.
