ciphergothAbout network switches. Can you join two cheapo (Dabs Value) 100BASE-T switches with a crossover cable?
One friend argues "no" on the grounds that before any switch will send a packet to the other, it would have to know of an address at the other end, but neither switch will know of any addresses on the other switch until some packets have been exchanged. (Is that right?) This makes sense, but it occurs to me that if switches broadcast any packets they don't know how to route then all will be well. I don't know if they do though.
I also have no idea what to do if I can't connect them this way! Possibly buy another PCMCIA Ethernet card for the laptop that's also the gateway, but they are costly.
Advice gratefully received...
