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.

1In the Device Panel list, select a device and then right-click.

2Click Configuration > Ethernet Port Configuration > DiffServ.

3Select 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).
