Chapter 3 Assigning the Switch IP Address and Default Gateway
Assigning Switch Information
If the dir flash command does not work, enter:
switch:
flash_init
:
This command initialize the flash so the contents can be read, without erasing any of the flash memory
contents.
After the switch becomes operational on an image, you can specify the image to boot from by using the
boot global configuration command. See the
“Modifying the Startup Configuration” section on
page 3-17
.
Assigning Switch Information
You can assign IP information through the switch setup program, through a DHCP server, or manually.
Use the switch setup program if you want to be prompted for specific IP information. With this program,
you can also configure a hostname and an enable secret password. It gives you the option of assigning a
Telnet password (to provide security during remote management). For more information about the setup
program, see the “Configuring the Switch with the CLI-Based Setup Program” appendix in the
hardware
installation guide.
Use a DHCP server for centralized control and automatic assignment of IP information after the server
is configured.
Note
If you are using DHCP, do not respond to any of the questions in the setup program until the switch
receives the dynamically assigned IP address and reads the configuration file.
If you are an experienced user familiar with the switch configuration steps, manually configure the
switch. Otherwise, use the setup program described previously.
