QoS for Cisco 1800 series routers?

Post by lobotiger »

Hi everyone. I'm wondering if anyone has any sample QoS configurations for Cisco IOS routers? I have a Cisco 1811 and am trying to setup oubound QoS on it but am having difficulty in matching the traffic.

So far I've tried matching on the specific ports mentioned in the FAQ but not all of the traffic is being caught in my ACL. Here's what I've got for matching so far:

ip access-list extended FREEPHONELINE
permit udp any 208.65.240.0 0.0.0.255 eq 13000
permit udp any 208.65.240.0 0.0.0.255 eq 13001
permit udp any 208.65.240.0 0.0.0.255 eq 5060
permit udp any 208.65.240.0 0.0.0.255 eq 5061
permit udp any 208.65.240.0 0.0.0.255 eq 6060
permit udp any 208.65.240.0 0.0.0.255 eq 6061
permit udp any eq 13000 208.65.240.0 0.0.0.255
permit udp any eq 13001 208.65.240.0 0.0.0.255
permit udp any eq 5060 208.65.240.0 0.0.0.255
permit udp any eq 5061 208.65.240.0 0.0.0.255
permit udp any eq 6060 208.65.240.0 0.0.0.255
permit udp any eq 6061 208.65.240.0 0.0.0.255
permit udp any 208.65.240.0 0.0.0.255

When I call the voicemail box, I get most of my traffic ending up on the last line as a match. This is fine but when I call some other number I don't get any matches. Is all voip communication from my PC going directly to that block of Class C? I'm pretty savvy at configuring QoS within IOS but tonight I'm pretty stuck at the match criteria. Would I be better off in trying to match RTP and/or SIP protocols instead? Is that how the flow from my PC to FPL is setup?

Any help would be appreciated it.

Thanks.
