Assigning Switch Information

The bootloader provides access to the flash file system before the operating system is loaded. Normally,
the bootloader is used only to load, uncompress, and launch the operating system. After the bootloader
gives the operating system control of the CPU, the bootloader is not active until the next system reset or
power-on.
The bootloader also provides trap-door access into the system if the operating system has problems
serious enough that it cannot be used. The trap-door mechanism provides enough access to the system
so that if it is necessary, you can format the flash file system, reinstall the operating system software
image by using the Xmodem Protocol, recover from a lost or forgotten password, and finally restart the
operating system. For more information, see the
page 40-2
You can disable password recovery. For more information, see the

Before you can assign switch information, make sure you have connected a PC or terminal to the console
port, and configured the PC or terminal-emulation software baud rate and character format to match
these of the switch console port:

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) and configuring your switch as a
standalone switch. For more information about the setup program, see the hardware installation guide.
Use a DHCP server for centralized control and automatic assignment of IP information after the server
is configured.
If you are using DHCP, do not respond to any of the questions in the setup program until the switch
Note
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.
