[configuration save]
Today when i access the router i show me this mode
rommon 1 >
IT guyz dont worry this will happen.
When a router/switch stuck in ROMMON mode, the first thing you need to check is the configuration register value.
The normal operation configuration register value is 0x2102, you can verify the value using the confreg command in the ROMMON prompt, or using show version in the normal prompt.
Here is the output you get if you have no problem with the configuration register:
rommon 1 > confreg
Configuration Summary
enabled are:
load rom after netboot fails
console baud: 9600
boot: image specified by the boot system commands
or default to: cisco2-C2600
do you wish to change the configuration? y/n [n]:
And this is the output if you have the wrong configuration register:
rommon 2 > confreg
Configuration Summary
enabled are:
load rom after netboot fails
console baud: 9600
boot: the ROM Monitor
do you wish to change the configuration? y/n [n]:
With the confreg command, you'll also prompted if you want to change the configuration register value. Type y if you want to change it or type n or press enter if you want to leave it.
If you type y, you'd be taken to a series of questions, just answer no to all but the change the boot characteristics, set the value on the next prompt to 2.
rommon 2 > confreg
Configuration Summary
enabled are:
load rom after netboot fails
console baud: 9600
boot: the ROM Monitor
do you wish to change the configuration? y/n [n]: y
enable "diagnostic mode"? y/n [n]:
enable "use net in IP bcast address"? y/n [n]:
disable "load rom after netboot fails"? y/n [n]:
enable "use all zero broadcast"? y/n [n]:
enable "break/abort has effect"? y/n [n]:
enable "ignore system config info"? y/n [n]:
change console baud rate? y/n [n]:
change the boot characteristics? y/n [n]: y
enter to boot:
0 = ROM Monitor
1 = the boot helper image
2-15 = boot system
[0]: 2
Configuration Summary
enabled are:
load rom after netboot fails
console baud: 9600
boot: image specified by the boot system commands
or default to: cisco2-C2600
do you wish to change the configuration? y/n [n]: n
You must reset or power cycle for new config to take effect
so at my case i just Reset the device using the following command:
rommon 3 > reset
After this command, It will decompress the image and start loading the device normally.
rommon 2 > boot flash:c2600-i-mz.122-10b.bin
program load complete, entry point: 0x80008000, size: 0x51c0dc
Self decompressing the image : #################################################
