Hi
I have a switched network here, with 10 - 12 switches, now there seems like one or two are acting like hubs, because I can se alot of traffic.
What can be reasons for this ? overload ? and is there some way i could check the switch, so i could determine the switch that is acting like the hub ?

Hi Tuva,
There can be several reasons for a switch to show the behaviour.
1) Asymmetric routing
2) Spanning tree related problems
3) Full CAM table
VTP should not be the reason for it. As a side note: you can have as many VTP servers as you want in a VTP domain and I would even recommend to have at least two, in case one of them goes down.
Back to your issues: can you please follow the troubleshooting instructions in "Unicast Flooding in Switched Campus Networks"

This might already solve your issues or help you understand, why it happens.
Hope this helps! Please rate all posts.
