Ip Prioritization; Differentiated Services (Diffserv) - Netopia 2200 series Software User's Manual

IP Prioritization

set ip prioritize [ off | on ]
Allows you to support traffic that has the TOS bit set. This defaults to off.

Differentiated Services (DiffServ)

The commands in this section are supported beginning with Firmware Version 7.4.2.
set diffserv option [ off | on ]
Turns the DiffServ option off (default) or on. on enables the service and IP TOS bits are
used, even if no flows are defined. Consequently, if the end-point nodes provide TOS set-
tings from an application that can be interpreted as one of the supported states, the Gate-
way will handle it as if it actively marked the TOS field itself.
☛
set diffserv lohi-ratio [ 60 - 100 percent ]
Sets a percentage between 60 and 100 used to regulate the level of packets allowed to be
pending in the low priority queue. The default is 92. It can be used in some degree to
adjust the relative throughput bandwidth for low- versus high-priority traffic.

NOTE:
The Gateway itself will not override TOS bit settings made by the endpoints.
Support for source-provided IP TOS priorities within the Gateway is achieved
simply by turning the DiffServe option "on" and by setting the lohi-asymmetry
to adjust the behavior of the Gateway's internal queues.
