Configuring the Host Name and Password

Chapter 3 Configuring with the Command-Line Interface

One of the first configuration tasks you might want to do is to configure the host name and set an encrypted password. Configuring a host name allows you to distinguish multiple Cisco VG224s and routers from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes.
