We have an Extreme Summit switch where I found that if you have two separate ports on different VLANs, and the same MAC address enters the switch on those two completely different VLANs, the switch will start having problems forwarding traffic. (Or only use the first entry in the FDB, I am not sure what it actually does other than half of the traffic drops.) Extreme support has confirmed that this is by design.
The reason I am posting this here is simple, does Cisco switches do the same thing? Or if MAC address comes from two ports on different VLAN, would it just forward per VLAN? Or would it depend on the model? I can think of so many possible problems with this that I want to see if this is common design of switches or just Extreme and I need to start using different L2 switches.
