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-config will differ from the results of the show startup-config command.
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:
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
