Differentiated Services (DiffServ)

set diffserv option [ off | on ]

Turns the DiffSer v 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 settings from an application that
can be interpreted as one of the suppor ted states, the Gateway will handle it as if it actively marked the
TOS field itself.

NOTE:

The Gateway itself will not override TOS bit settings made by the endpoints. Suppor t for
source-provided IP TOS priorities within the Gateway is achieved simply by turning the Diff-
Ser ve option “on” and by setting the lohi-asymmetr y to adjust the behavior of the Gate-
way’s internal queues.

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 through-
put bandwidth for low- versus high-priority traffic.

NOTE:

diffserv lohi-ratio has been removed for VDSL, ADSL bonded units.
