I've a catalyst 3560 (gbit/poe) switch with a voice enabled router 2851.
At the switch and router i've 3 vlans 1(native), 100(voice), 200(video). I also have an 7941 ip phone with a HP thins client attached. I'm using the smartport to setup the ports. As long as I'm using vlan 1 everything is working. When I set my access vlan to 1 and my voice vlan to 100 the thin client is losing the connection after aprox 10 second of no activity. When I keep working the connection is maintained. Any thoughts
