I have a Catalyst 3750G 48p PoE switch. When i firs set it up, i had a piece of paper and a pen (which i still have) that i wrote username and password on. So i still have this.
However, the switch no longer accepts that username and password. I can guarantee 1000% that the password written down is accurate, however it no longer works. What happened? Is my network breached? How can i enter the switch and at least dump the config?
I guess getting in is useless? How about console cable? I know about how to reset to factory defaults, but i really do have to avoid that. Thanks.
There is can be a lot of reasons why your password not works after puting it. you can try to find a reason after getting access to the configuration.
If tou didn't use a "write" or "copy running-config startup-config" you can just reboot your switch. If you did you can use this to drop a password (you need a console cable for it): http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/12040-pswdrec-2900xl.html
After running system from a rommon you can look at config (the command is "more flash:Config.txt") before installing a new password.
