Not sure I understand where you are aiming with your questions...
What would you do if you cannot enter the router? aren't this
childplay?
who would do such a thing ? :) on the production routers that
is...this is
unpractical...shouldn't even have to troubleshoot this one. I've
never
enunter this problem in real life before. Let me know if anyone
has.
Once, in my prep lab for the exam, in every one of my routers under line con
0, instead of entering "no exec-timeout", I entered "no exec". Guess what
happened? Once I exited the router, I could not get back in via reverse
telnet. Accidents happen, passwords are forgotten, and you should know how
to recover from those.
I'll send that sucker back for a different one :) rather
than trying changing the baud rate.
Why would anyone want to go through the process of returning a working
router, when a misconfiguration could be fixed in less than 5 minutes?
For example if someone telnet into the router put line con 0 in
no exec, then that person change all the ip addresses on the
interfaces.
on the last one he will be kick out but can telnet in again with the
new ip
and write mem what can you do to get in without having to
reconfigure the
whole router?
No different from password recovery.
