Catalyst 3750-X and 3560-X Switch Boot Loader
Commands
This appendix describes the boot loader commands on the Catalyst 3750-X and 3560-X switch. Unless
otherwise noted, the term switch refers to a standalone switch and to a switch stack.
During normal boot loader operation, you are not presented with the boot loader command-line prompt.
You gain access to the boot loader command line if the switch is set to manually boot, if an error occurs
during power-on self test (POST) DRAM testing, or if an error occurs while loading the operating system
(a corrupted Cisco IOS image). You can also access the boot loader if you have lost or forgotten the
switch password.
The default switch configuration allows an end user with physical access to the switch to recover from
Note
a lost password by interrupting the boot process while the switch is powering up and then entering a new
password. The password recovery disable feature allows the system administrator to protect access to
the switch password by disabling part of this functionality and allowing the user to interrupt the boot
process only by agreeing to set the system back to the default configuration. With password recovery
disabled, the user can still interrupt the boot process and change the password, but the configuration file
(config.text) and the VLAN database file (vlan.dat) are deleted. For more information, see the software
configuration guide for this release.
You can access the boot loader through a switch console connection at 9600 b/s. Unplug the switch
power cord, and press the switch Mode button while reconnecting the power cord. You can release the
Mode button a second or two after the LED above port 1X goes off. You should then see the boot loader
Switch: prompt. The boot loader performs low-level CPU initialization, performs POST, and loads a
default operating system image into memory.
