This command has no default configuration.

Class-Map Configuration mode

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.

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

Use the match protocol command in Class-Map Configuration mode to add 

to the specified class definition a match condition based on the value of the 

IP Protocol field in a packet using a single keyword notation or a numeric 

value notation.

match protocol {

protocol-name|protocol-number}
