Configure the Hostname for Switch Identification
Step 1 Configure the hostname on a switch to identify the switch in your network. By default, the system name
and prompt are Switch.
Set the hostname for the switch product family, the role of the switch in your network, and the switch
location.
Note that the system name is also used as the system prompt.
If you have not configured a system prompt, the first 20 characters of the system name are used as the
system prompt. A greater-than symbol [>] is appended. The prompt is updated whenever the system
name changes.
This example is for the switch serving as an access layer switch located on the first floor of Building 1
.
Note Users can now proceed to the Configure Secure HTTPS ans Secure Shell for Secure LAN Management
section.
Configure Secure HTTPS and Secure Shell for Secure LAN Management
Step 2 Disable the HTTP and Telnet unencrypted protocols on the switch.
Step 3 Configure Secure HTTP (HTTPS) and Secure Shell (SSH) to enable secure management of the switch.
Enabling HTTPS automatically generates a cryptographic key to use the service. When SSH is
configured after HTTPS, you do not have to explicitly generate the cryptographic key that SSH requires,
unless you want to change the default key size.
We recommend that you use the transport preferred none command on the VTY lines to prevent
connection attempt errors from the CLI prompt. Without this command, your IP name server may
become unreachable, and long timeout delays may occur..
Note If the switch acts as a Web authentication server or as an authentication proxy, then do not disable the
HTTP server by executing the no ip http server command.
hostname 3850-access-Bld1Flr1
ip http secure-server
ip ssh version 2
!
line vty 0 15
transport input ssh
transport preferred none
