4510 telnet connection problem

thecoder35
Level 1
Level 1

We desided to install cisco network assistant. After the installation we had telnet connection problem to 4510+r, and standby sup restarted changed to standbuy cold.Before the installation everything was fine. Also after installation, commandline configuration changed :

Before the installation:

line vty 0 4

password *****

login

line vty 5 15

password *****

login

after installation:

line 1 16

exec-timeout 2 0

password *******

exec-character-bits 8

no exec

length 0

width 0

no history

international

transport input all

speed 9600

when I'm trying to connect from PC it show following error:

could not open connection to the host on port 23 connect failed

putty refused this connection.

when im trying to type config to vty sh run doesn't show this configuration.

I can't remove Line 1 16.

After line clear problem not solved. also tried: no exec transport input note,all, telnet Login Local no Login

but no result. No any Line vty config on sh run.

Try this:

line 1 16

exec

That should get you back in...

I tried but it did not work

I don't have access to a 4500 switch. Can you create your lines? You said that you cannot remove "line 1 16", but can you create "line vty 0 4"?

Try below:

line vty 0 4

password

exec

login

John
