VLAN cross talk? such a thing? VLAN Traffic broadcasting accross other VLANs
This question is far out there but I am going to ask this anyway. I work with a group of guys that think they know everything about networking and have all of the answers. Here is a statement one was proposing was a cause to a traffic problem on our network. We have a network that when you sniff traffic you can see VLAN traffic from host on other VLANS communicating that should not be broadcast within the VLAN your on. Granted this is a problem but one of the reasons for this was that we are experiencing VLAN cross talk. What is this? It was explained to me that VLAN cross talk is when a switch is overloaded and will send a broadcast to all ports regardless of VLAN membership. This was news to me and I have never heard of such a thing. I can believe we are having routing issues or trunks that are misconfigured but VLAN cross talk? This sounds like someone made up to sound like they think they know whats going on. Has anyone heard of such?
