Security
To prevent unauthorized access to your switch you should configure one or more of the following security features. Passwords on the console and vty lines, username/password pairs stored locally on the switch for individual access, username/password pairs stored on a centrally located server (i.e. TACACS+, or RADIUS). You can also configure privilege levels for passwords. When a user enters the password you have given them they can be granted access at a pre-defined privilege level.
If you have placed the switch in a location that you cannot completely secure, you might want to consider disabling password recovery. With the 搉o service password-recovery?command, you can disable the option for someone who has physical access to perform password recovery and gain full access to your switch. If you have password-recovery disabled and a user interrupts the boot process they are asked if they would like to proceed and erase the configuration, if they do not want to erase the configuration, the normal configuration is loaded and the user still can抰 gain access.
SSH
SSH is a protocol that provides a secure, remote connection to a Layer 2 or a Layer 3 device. There are two versions of SSH: SSH version 1 and SSH version 2. This software release only supports SSH version 1. SSH provides more security for remote connections than Telnet by providing strong encryption when a device is authenticated. The SSH feature has an SSH server and an SSH integrated client. The client supports these user authentication methods: TACACS+, RADIUS and Local Username authentication.
To configure SSH on your switch perform the following commands after you have verified you have the crypto image: hostname ip domain-name
