IP DSCP mapping

The IP DSCP mapping table allows you to assign a traffic class to every DSCP value.

The different DSCP values get the device to employ a different forwarding behavior, namely Per-Hop Behavior (PHB).
PHB classes:

DSCP value

DSCP name

Traffic class for RS20/RS30/RS40, MS20/MS30, RSR20/RSR30, MACH 100, MACH 1000, OCTOPUS
(default setting)

Traffic class for MACH 4000 and
PowerMICE
(default setting)
