I have some SIP phones on one network that go through an IPIP tunnel to get to the server.
I've setup QOS rules to watch for appropriate VOIP traffic as follows:
class-map match-any class-voice description Voice match dscp af11 match dscp cs4 match dscp cs3 ! policy-map qos-out class class-voice priority 100 ! interface Tunnel1 description Tunnel to VOIP Server ip address 10.10.0.2 255.255.255.252 tunnel source FastEthernet0/1 tunnel destination 172.16.100.100 tunnel mode ipip ! interface FastEthernet0/1 description Internet bandwidth 1000 ip address dhcp service-policy output qos-out
My trouble is that the class-map isn't getting matched because I can't assign the policy to the Tunnel1, only FastEthernet0/1.
Surely there must be something to make this work... what should I do?
