Also, I cannot recommend enough the QoS Book for the 642-642 exam by Odam, a great book... It basically reads itself... the best Cisco Press book I have ever read (for downright usefulness the Configuring Cisco CallManager and Unity by Bateman...

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">You want to use match-any. Match-all
means the packet must match all criteria defined in your map or it does not
match. Match-any is any single description in your maps. Currently,
your signaling map does not match any of the traffic you're trying to
classify due to this behavior. AF31 is bit structure 011010 and CS3 is
011000. There won't be a packet that matches both. You want
it to be an "either" statement, not an "and" so use
match-any. Also, if you use match-any, you can collapse your class-maps
for signaling into one map rather than two, which is cleaner. Here is a
collapsed map that works.</span></font></p>
