Hi all, can anyone tell me why we have to use a crossover cable to connect switches together ? how come pc's dont need this, is it because on a nic, they are already opposite transmit and receive ports as standard, also how come we dont need a crossover to connect to a hub ?
Your question doesn't really have a straight answer because it's all about perspective.
The important thing is to remember that the transmit on one side goes into the receive of the other. For a traditional switch to switch (ie not including auto mdix), this means using a cross over cable. When connecting a PC to a switch (or router to a switch), you use a straight through cable. When connecting 'like' devices (eg pc to pc, switch to switch), you traditionally had to use a x-over cable - again, excluding features such as auto mdix, and uplink ports.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
