Assigning Switch Information - Cisco IE 3000 Software Configuration Manual

Assigning Switch Information

The boot loader provides access to the flash file system before the operating system is loaded. Normally,
the boot loader is used only to load, uncompress, and launch the operating system. After the boot loader
gives the operating system control of the CPU, the boot loader is not active until the next system reset
or power-on.
The switch has a removable compact flash card that stores the Cisco IOS software image and
configuration files. You can replace and upgrade the switch without reconfiguring the switch. Removing
the compact flash card does not interrupt switch operation, unless you need to reload the Cisco IOS software
because of a power cycle or user action. However, when the compact flash card is removed, you do not have
access to the flash file system, and any attempt to access it generates an error message. The switch ships with
the compact flash memory card installed and supports any size compact flash card.
Use the show flash: privileged EXEC command to display the compact flash file settings. For more
information about the command, go to this URL:

For information about how to remove or replace the compact flash memory card on the switch, see the
Cisco IE 3000 Hardware Installation Guide.
The boot loader 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 34-2
You can disable password recovery. For more information, see the
Note
section on page
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
command or member switch of a cluster or as a standalone switch. For more information about the setup
program, see the hardware installation guide.
