Hello to all,
I am trying to configure a QoS for my WAN. I have a cisco 881 router with advanced ip services. My problem is my wan comes from a cable modem which the router connects via a fast ethernet port. Also, the ISP provider guarantees a minimum upstream bandwidth of 64kbs when congested and up to 512kbps when network is available.
I am interested in enforcing traffic shaping to 96kbps only when an rtp stream is active. If there are no rtp packets flowing then I'd like the cable modem to take care of the upstream queues.
I am trying with this configuration but it is locking my upstream to 96kbps at all times..
class-map match-any voice-traffic
match dscp ef
class-map match-any voice-signal
match dscp af31
shape average 96000 9600 0

I am a CCNA student so your help would be highly appreciated.
