Configuring a Hostname of a Cisco Switch

July 31, 2015 by Rowell Dionicio Leave a Comment

Cisco Catalyst 2960XAre you just starting to study for the CCNA ICND1 certification? One of the objectives of the certification is to configure the hostname of a switch.

During the setup of a Cisco switch there is one configuration command that sets the hostname. The following commands were performed on a Cisco Catalyst 2960 switch.

Configure a Switch Hostname

From User EXEC mode, the device name will be part of the prompt which right now is just Router. To change the hostname of the router we need to enter User EXEC mode and then into Privileged EXEC mode.

Switch>enable
Switch#
Switch#configure terminal
Switch(config)#

Now that we are in Global Configuration Mode, we issue the hostname command followed by the name we want to give this router and hit Enter.

Switch(config)#hostname Core-Switch-A
Core-Switch-A(config)#

Notice after you hit Enter, the prompt changes to the hostname you just configured. The change gets put into the running-config. To save the changes you make the running-config must be saved to the startup-config.

The syntax is as follows hostname device-name

hostname command starts the whole command which then needs to be followed by your input.
device-name can be anything from your input to name this device.

To save the running-config we must leave Global Configuration Mode and go back to the User EXEC Mode.

Core-Switch-A(config)#end
Core-Switch-A#

Now to save your changes to the startup-config we tell the router to save what changes are in the running-config to the startup-config.

Core-Switch-A#copy running-config startup-config

Verify Hostname Configuration

You can verify if the hostname configuration stuck by checking the user prompt. It should display the switch hostname. You will also verify the configuration in the running configuration on the hostname line.

Core-Switch-A#show running-config
 Building configuration...
Current configuration : 1050 bytes
 !
 version 12.2
 !
 hostname Core-Switch-A
Full Hostname Configuration
Switch#configure terminal
Switch(config)#hostname Core-Switch-A
Core-Switch-A(config)#end
Core-Switch-A#copy running-config startup-config

Putting it all together in one single configuration.

Switch>enable
Switch#
Switch#configure terminal
Switch(config)#hostname Core-Switch-A
Core-Switch-A(config)#
