I'm setting up a computer lab at a facility whose network I do not manage. The IT guy on staff knows absolutely nothing about networking. The contractor they use is on vacation. From everything I've seen, all their hardware is Netgear, unmanaged, and the network is one big 22-bit subnet.
There's a drop in the lab. If I connect a PC to it, I get an address from DHCP. If I connect a switch, and then a PC to the switch, I get nothing.
The switch is a non-configured Cisco 2960. I didn't know the command off the top of my head to have the trunk interface request a DHCP address, and it was past quittin' time, so I left.
The only time I've seen this happen is when I had spanning-tree portfast on an access port, forgot, and put a little workgroup switch on the port.
Any thoughts on what I can try in the morning? I'm really hoping to only be there an hour or two.
