I have to say thanks to all of you for the help that can brings us in this forum. In this time I have a question that almost all people thinks about "piece of cake" but I dont really have a idea what's the real funtion of the "Mode Button" in the Switch Catalyst. I have a experience, the last week when I have encommended to find a cable in the rack, accidentally I hit the mode button with the "tracer pencil" and all trunk interfaces turn off their light and the rest of the interfaces looked like a christmas tree for a 30 seconds. Someone could explain? I appreciated that.
Psdt: Dont worry about the english, the next week will be better.
It's used in combination with the port LEDs for checking the status of ports and also the
utilisation on the switch etc. However, they're not the easiest of indicators to remember so
using it for password recovery is about its most useful feature.
Here's a link to the old 3550 switches (I presume it's similar on newer Catalyst switches)
