ToS to DSCP Value Conversions
Application devices or remarking devices often have different ways of display-
ing or configuring the ToS or DSCP values used to mark packets. Some devices
require the user to input the ToS value while others require input of the DSCP
value. Depending on the manufacturer, these values may be displayed in binary,
decimal, or hexadecimal formats.
The information below can be used to convert between various formats:
Convert from ToS to DSCP - Divide the ToS decimal value by 4
Example : Convert a ToS decimal value of 184 to DSCP
DSCP = 184/4
DSCP = 46
Converting ToS and DSCP to/from Binary - Figure E-14 provides an example
of the conversion to and from binary and can also be used to convert to and from
ToS and DHCP values.
