The following table describes the labels in this screen.
16.14 DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-
hop treatment at DiffServ-compliant network devices along the route based on the application
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the
level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate
paths or remember state information for every flow. In addition, applications do not have to
request a particular service or give advanced notice of where the traffic is going.
Enable DiffServ in the DiffServ screen.
1 In the Device Panel list, select a device and then right-click.
2 Click Configuration > Ethernet Port Configuration > DiffServ.
3 Select Active to enable the DSCP-to-IEEE 802.1q mapping. Set the mapping in the IP
Configuration: DSCP screen (refer to Section 19.2 on page 201).
