You can "erase start" from previliged mode and restart the switch. It will bootup with default config.

I think I am stuck in ROMMON but I am not sure, when I connect the switch with console port, only "switch:" is written on the console.

when "?" is entered those output comes

switch: ?

when I unplug the power cord then I push the mode button and plug the power cord, after a certain time this output is appeared

The password-recovery mechanism is enabled.

The system has been interrupted prior to initializing the

flash filesystem. The following commands will initialize

the flash filesystem, and finish loading the operating

if the switch is stuck in "Rommon " mode when you see through the console, probably it is not finding the boot image. See with dir slot0: or dir bootdisk: and once you get the image name, say boot bootdisk: or boot slot0:imagename depending on where the image is located.

I typed

switch: dir slot0

unable to stat slot0/: no such device

switch: dir

List of filesystems currently registered:

flash[0]: (read-write)

xmodem[1]: (read-only)

null[2]: (read-write)

switch: boot bootdisk:flash (and tried with xmodem and null)

Loading "bootdisk:flash"...bootdisk:flash: no such device

Error loading "bootdisk:flash"

Interrupt within 5 seconds to abort boot process.

Boot process failed...

switch: help boot

Usage for "boot" is:

boot [-n|-j] [-p] [-c] [-f] [-i] [-m] [-notnd] [-notni] [-post] [-skip_post]

[-reserve_mem <1-15>] [-no_esp_keepalive] []

I dont know what to do now, could u tell me what should I do ?

Do a "dir flash: and see if there is any image in there. If there is issue a "boot flash: command and see if it will boot other wise you will have to go thru a image recovery procedure . Doing what you did would not have erased the image file , someone else would have had to erase the file while it was powered up and you were the unlucky person who tried to erase the config.
