Hello, I am trying to troubleshoot poor video quality over a 2Mb WAN link (frame relay) The video is jerky and of relatively poor quality compared to the demonstration example. The hardware is Tandberg, the ip address of the box on network A is 172.16.1.16 and on network B it is 172.16.2.105.
The cisco configs look fine to me, after some research on the internet it seems that the problem could well be autonegotiation of the ethernet ports connected to the Tandberg boxes (apparently they should be set to 100 /Full Duplex).
I would be very grateful if someone could double check these configs for me just to be more sure that it is not a QoS problem!
Thanks in advance.
