I am an embedded software developer, and have a need to find a switch that will support two LAN's, with the traffic completely segregated. Can any of Cisco's switches do this? What would such a feature be called?
Here's how it will be used:
When developing new hardware, the test board has a single ethernet port. Currently, I connect the port to our company network to tftp code into the hardware, then physically move the cable to the test network that injects packets. Since I am continually fixing bugs and testing, I move the cable back and forth about every 10-15 minutes.
In order to telecommute, I need a way to be able to switch the cable between the two LAN's. The ideal would be to connect my hardware to a switch that had the two LAN's segregated -- then to just reconfigure the switch as needed so that my port was in one LAN or the other.
