Chapter 3 Configurations for the Layer 3 Switch Router

Configuring the Hostname

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

Router# show startup-config

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

Configuring the Hostname

In addition to the system passwords and enable password, your initial configuration should include the hostname to make it easier to configure and troubleshoot the Layer 3 switch router. To configure the hostname, perform the following task, beginning in enable mode:

 

Command

Purpose

Step 1

 

 

Router# configure terminal

Enter global configuration mode.

 

Router(config)#

 

Step 2

Step 4

 

 

Router# copy running-config startup-config

Copy your configuration changes to NVRAM.

 

 

 

Using the Bootflash Memory SIMM

The Catalyst 2948G-L3 and Catalyst 4908G-L3 switch routers use the onboard bootflash memory as the file storage system. The bootflash memory single inline memory module (SIMM) stores a copy of the Layer 3 switch router’s software image. The following sections describe how to use the bootflash memory SIMM to perform system administration:

•Viewing the Contents of Bootflash Memory, page 3-5

•Deleting Files from Bootflash Memory, page 3-6

•Backing Up a System Image to a TFTP Server, page 3-6

•Copying a System Image from a TFTP Server to a Bootflash Memory SIMM, page 3-7

•Erasing Files from a Full Bootflash Memory SIMM, page 3-8

Viewing the Contents of Bootflash Memory

You can perform the following tasks to view the contents of the onboard bootflash memory SIMM:

•To determine which file system device you are accessing, enter the print working directory (pwd) command.

Router# pwd bootflash:
