I work for a company with a large frame relay network which is set up as follows:
We have 1 main site with around 35 PVC's going into it. One of those PVC's goes to another large site which also supports many of its own PVC's. Both of these sites have been configured with a single subinterface, into which all PVC's go.(all done with cisco kit-1600, 3620, 3640 and 3660's). Hope that makes sense!!
OK, so the problem I have is this... I am based at the main site and occasionally response between here and the other large site becomes very slow (people think it's gone down). I use Solarwinds Bandwidth Monitor to check each end, sure enough they are being hammered. My goal is to find what is hammering the link. The way in which the frame is configured here makes this very difficult.
Because all PVC's terminate into the same subinterface at both these sites I cannot be sure that it is traffic between these 2 sites which is making it slow.
What I really want is some way of monitoring the utilization of each PVC as opposed to the utilization of the interface (all PVC's bundled together). Also what would be handy is a way of actually identifying what types of data are travelling across my WAN links as this may help me locate the culprit, maybe then I could also consider a packet shaping solution??
Should I consider putting each DLCI onto their own subinterface? I hope I've made this clear as it is driving me mad. Every time I think I might find what is doing it, the line goes quiet again.
