Cisco Systems 3 manual Configuring the Host Name, Using the Boot Flash Memory SIMM

Chapter 3 Initial Switch Router Configurations

Configuring the Host Name

You can display the configuration file when you are in privileged EXEC (enable) mode.

•To see the current operating configuration, enter the following command at the enable prompt:

Router# show running-config

•To see the configuration in NVRAM, enter the following command:

Router# show startup-config

If you made changes to the configuration, but did not yet write the changes to NVRAM, the results of the show running-configwill differ from the results of the show startup-configcommand.

Configuring the Host Name

In addition to the system passwords and enable password, your initial configuration should include the host name to make it easier to configure and troubleshoot the switch router. To configure the host name, use the following steps beginning in enable mode:

	Command	Purpose
Step 1
	Router# configure terminal	Enters global configuration mode.
	Router(config)#
Step 2
	Router(config)# hostname name-string	Enters a system name. In this example, we set
		the hostname to “Router.”
Step 3
	Router(config)# end	Returns to privileged EXEC mode.
	Router#
Step 4
	Router# copy running-config startup-config	Copies your configuration changes to
		NVRAM.

Using the Boot Flash Memory SIMM

The Catalyst 2948G-L3 and Catalyst 4908G-L3 switch routers use the onboard boot flash memory as the file storage system. The boot flash memory SIMM stores a copy of the switch router’s software image. This section describes how to use the boot flash memory SIMM to perform the following system administration tasks:

•Viewing the Contents of Boot Flash Memory

•Deleting Files from Boot Flash Memory

•Backing Up a System Image to a TFTP Server

•Copying a System Image from a TFTP Server to a Boot Flash Memory SIMM

•Erasing Files from a Full Boot Flash Memory SIMM
