I was so delighted and totally surprised today to finally be informed about what was going on with the
"switchport trunk encapsulation dot1q" command.
I did not realize this was just for switch to switch communications. That is very valuable to know :-)
So the episode did bring two questions to my mind.
The first question is about the need for a crossover cable to be able to setup uplinks and trunks between switches.
I was dumped head first into an enterprise network without training, so I may be a little behind on this. But I do not think we are using crossover cables for any of our work. So I am wondering if maybe that is because the switches we use now are auto detecting and compensating for us?
The second question I have is, how would you set up a trunk between a switch and a router to pass all vlans? Do routers kill vlan tagging? Or do they pass it by default.
