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 (port-based) or DSCP (DiffServ), you can
configure the switch so that certain traffic will take priority over less critical traffic.
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 5-32: 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.
