I'm trying to configure a vty password in packet tracer and I think I'm doing something wrong. These are the commands I'm using:
line vty 0
password test
end
When I do showrun I can see the command, but when I try to get access to the vty line, it never ask's me for the password. What am I doing wrong.
Screen shot included. Thanks.

Hi,
You can check using below steps,
1. Connect two switches
2. Configure IP address in Vlan 1 interface on any one switch
3. Configure enable password
4. Configure line vty on same switch
Then telnet configured ip from another switch.
Example,
Step 2:
Switch1(config)#int vlan1
Switch1(config-if)#ip address 10.0.0.1 255.0.0.0
Switch1(config-if)#no shut
Step 3:
Switch1(config)#enable password cisco
Step 4:
Switch1(config)#line vty 0 4
Switch1(config-line)#password cisco
Switch1(config-line)#login
To check:
Switch2#telnet 10.0.0.1

Well if you can't ping then you can't telnet.
You need to work out why you have no connectivity.

Have not used packet tracer, but try
line vty 0 15
or
line vty 0 4
and add the password and test again.

Thanks for the help. I will try but I have question. After I configure the line vty o, what is the command to test it to see if it will ask me for the password?

Just log out and log back in to the device.

I did log out, then I logged back in. what is the command I need to use to try and access the vty 0 4 lines?

There is no specific command. You just open a session to the device via putty, secure CRT, etc.. and that session will use one of the vty lines.

Thanks, I will try this when I get home.

Thank you for the information. I completed all the steps in your instructions except the last one:
Switch2#telnet 10.0.0.1
I don't know how to telnet into the sw2. How do I do this without using putty. Can you please show me how to do this? Thank You.

I hope you wanted to understand how line vty is working.
If yes, then login switch2 via console and telnet switch1 using ip which is configured for Vlan1 in the switch1.

I have followed your instructions. Sw01 is on vlan 1, ip address 10.0.0.1 subnet mask 255.0.0.0. Sw02 is on vlan 1, ip address 10.0.0.2 subnet mask 255.0.0.0. I have a console connection to sw02. Then I open a new terminal connection and I use enable command. Then I type, telnet 10.0.01, then it says connection timed out; remote host not responding.

What do you mean you opened a new terminal connection.
If you have a console connection just telnet from there.

I'm doing this in packet tracer. I have a laptop with a console cable connected to sw02. On the laptop, I click on desktop, terminal, then I log on to the switch. Then after enable, I type:
telnet 10.0.0.1
04-14-2015 02:03 PM
Can you ping the other switch ?
Jon
04-14-2015 02:23 PM
No, I cannot ping sw01 10.0.0.1 or sw02 10.0.0.2. I'm pinging from the pc which is connected via console cable into sw02.
I found this video on youtube:
https://www.youtube.com/watch?v=6jTArL-qvIY
At first it did not work, but then I used these commands and it worked:
switch(config)#line vty 0 15
switch(config-line)#password cisco
switch(config-line)#transport input telnet
switch(config-line)#login
switch(config-line)#exit
Then I used the same commands on the both sw01 & sw02, but it still does not work.
