The devices I'm working with come off the production line all set to the same MAC address. I can set each one to have their own static IP, and I'm wondering if there would be a way to connect them to the network at the same time in order to transmit configuration data (including a new MAC address) to them?
I've got a Cisco SF 200-24 "Smart Switch", and so far I've tried setting each port on the switch to its own VLAN (mode: access), with another port set to be on all of the VLANs as a trunk line to an upstream server I'd like the units to talk to.
Right now I've set each device to have a static IP on their side, but I seem to be having trouble getting them to talk to the upstream computer through the trunk line. I don't expect (or want) the devices to be able to talk to each other, just the server connected to the trunk port.
Is what I'm doing feasible with the equipment I have, or am I going to be stuck configuring each one individually?
"You're an idiot, don't connect things with the same MAC to the same network" may also be an acceptable answer here, but I'm hoping there might be a more interesting one.
EDIT: Hah, people are passionate about their networking hardware on here. I suppose I shouldn't be surprised. I've inherited this lovely legacy design, and I get to put up with this until I can get a new firmware rev to our manufacturer. Thanks for participating, folks.
