Hey guys,
So, I have a doosy for everyone. I am not looking for answers, but possibly suggestions that could point me in the right direction as to where to look to troubleshoot this issue.
The Issue:
Client with multiple wan links bought 7 HDX systems and an RMX bridge. Great systems, but no matter what speed, the picture quality on the bridge or a P2P is always the same. You will get artifacts, jerky video, ghosting... As well, there is a constant pulse in the video. From speaking with Polycom it seems that this occurs when the discarded packet buffer is full, it cycles. Normally this shouldnt happen every 2 seconds.heh
The network is currently QoS'd, but the traffic is shared equally between voip traffic and VC (pretty much, all packets traversing on ports X-X are given an EF tag).
Troubleshooting Done:
- All switches and endpoints are forced to 100/full.
- QoS is enabled across the network. The network was designed to handle VOIP, not so much VC.
- Connected an endpoint on the same switch as RMX bridge, same results (poor video, ghosting, etc)
- Connected an endpoint on same VLAN as RMX bridge, same results (poor video, ghosting, etc).
- Connected an endpoint DIRECTLY into the RMX bridge, video worked perfectly.
- Placed all ports which the RMX and endpoints use for VC onto the QoS port shaping.
I know, long winded. But thought I would give everyone the facts and details. I know it is leaning more towards network side than anything. It is almost like... hmm... the packets once they get to the endpoint are have troubles being in the right order. like as if there is no FIFO ordering? if that makes sense..
Anyone have any ideas?
