Re: Cant console into Catalyst 4507

Hi. You can't get that message from a console. That means you are doing something incorrectly.

You might have an authentication method problem on the AUX line, on the router you are remote logging from. Or maybe you forgot to allow login?

Do this on that router (if it's clean running config):

conf t

ena sec cisco

line vty 0 4

pass cisco

login

linex aux 0

pass cisco

login

transport input all

int lo 0

ip add 1.1.1.1 255.255.255.255

end

telnet 1.1.1.1 2017

(the port number for reverse telnet is 2000 + the number that you see from "sh line | in AUX|aux"

Also,

changing configuration register to 0x2102 on the 4507 would be nice

Re: Cant console into Catalyst 4507

Hi,

Thanks for your reply.

I followed your steps exactly, I got this output

Router#telnet 1.1.1.1 2001

Trying 1.1.1.1, 2001 ... Open

User Access Verification

Password:

Password OK

but I cant type anything, everything freezes there.

As for the conf reg, I cant change it, because I cant type anything at all.......
