Hello, I had a question about a solution in the DSG1, question 2.7: "On CAT4, any non-voice traffic on the data or guest VLANs should be set to use the default COS value. Voice traffic should be trusted."
In the solution section there are child policies configured with interfaces and exceed actions, but I don't understand why do I have to configure these child policies, why doesn't it enough just to trust dscp or cos values for voice/signaling traffic and set just the class-default non-voice traffic to dscp default? If I want to match both interfaces and acl, I could do it under the first RTP-CM as well. Like: class-map match-all RTP-CM match access-group name RTP-ACL match input-interface FastEthernet1/0/1 ... where am I wrong? Can you clarify? Congrat' to Jay! Thanks and Best Regards Istvan
