Hello,

If I understood correctly, you are asking about configuration by telnet or SSH as opposed to console.

For Telnet,

Config terminal

line vty 0 15

password  mypassword

login

***********************

Telnet is not secure so you should use SSH.

*******************

Config terminal

username cisco secret cisco [use your own user and password]

Ip domain-name cisco

Ip ssh version 2

crypto key generate RSA

line vty 0 15

login local

service-password encryption  ( just protects password from over shoulder look)

Remember to config enable password

*******************************************

The configuration above was just a basic config for telnet and SSH connectivity.

As Peter mentioned, using centerized server gives you much better protection.

Hope it helps,

Masoud

Hi

The command R1(config)#enable password mypassword is the correct global configuration command for configuring a password for enable or configuration mode.

You can also use R1(config)#enable secret mypassword   as this will encrypt the password.

To add password for connecting (tellnetting or ssh) to vty, you use

R1config t

R1(config)#line vty 0 4

R1(config-line)#password mypassword

in line configuration mode

and for the console password:

R1config t

R1(config)#line con 0

R1(config-line)#password mypassword

Hope this helps
