Thank blakley and Thotsaphon for quick reply.
I wanna to ask that what is the meaning of vty 5 15? vty 0 x mean the first telnet login connection?
just want to make sure that both command correct. otherwise can't login the router again.
Older versions of IOS allocated only 5 "terminal" lines for telnet connections - VTY 0 - 4
"Modern" versions of IOS allocate 16 "terminal" lines for telnet connections - VTY 0 - 15.
They are separated into two groups in your configurations to allow for backward compatibility - you can cut and paste a configuration from an "old" IOS into a "modern" IOS and it'll still work.
Simply duplicate the statements you have for lines 0 - 4 for the rest. Depending on the switch/router model, you can either do
line vty 0 15
login
password keepout
transport input telnet
or
line vty 0 4
login
password keepout
transport input telnet
line vty 5 15
login
password keepout
transport input telnet
If you're NOT running encrypted passwords, then the displaying the passwords should be the same. if, however, you have encryption on passwords (the command "service password-encryption" in your active configuration), the same plain text password can be encrypted with two different results.
The folowing lines
username fred1 privilege 15 password 7 110F0B001343
username fred2 privilege 15 password 7 121F1712165A
contain the same password - yet the result is different. You can check this by putting the passwords (the but after the password 7 section) into the following web page
http://www.ibeast.com/content/tools/CiscoPassword/index.asp
and you'll see the same answer for the decrypted password.
So, the answer to your original question is - you probably have the same password for lines 0-4 as you do for lines 5-15 - it's just encrypted differently.
Cheers.
