octet in the IP header.

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.
This specification is the
free form version of the IP DSCP/Precedence/TOS
match specification in that you have complete control of specifying which
bits of the IP Service Type field are checked.
Example
The following example displays adding a match condition based on the value
of the IP TOS field in a packet.
console(config-classmap)#match ip tos AA EF
