User Guidelines
The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a match
criterion for the same Service Type field in the IP header but with a slightly different user
notation.
To specify a match on all precedence values, use the match ip tos
with tosbits set to "0" (zero) and tosmask set to hex "1F."
Example
The following example displays adding a match condition based on the value of the IP
precedence field.
console(config-classmap)#match ip precedence 1
match ip tos
Use the match ip tos command in Class-Map Configuration mode to add to the specified class
definition a match condition based on the value of the IP TOS field in a packet. This field is
defined as all eight bits of the Service Type octet in the IP header.
Syntax
match ip tos
tosbits — Specifies a two-digit hexadecimal number. (Range: 00–ff)
•
tosmask — Specifies the bit positions in the tosbits parameter that are used for comparison
•
against the IP TOS field in a packet. This value of this parameter is expressed as a two-digit
hexadecimal number. (Range: 00–ff)
