QoS Commands 407
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
