Hi Glen,

I already tried this method but on resetting the hub switch, it again asks the username for authentication instead of Switch> prompt. I also tried to unplug the Core Switches Uplink cable to discunnect the AAA Server but the result is same.If you have any idea, please help me out.

Do you get to the rommon prompt and then enter confreg 0x2142 ? If the register has been set I don't know how it could give you anything other than a switch with a blank config as it bypasses your startup config in this mode .You then copy your startup into running config and you modify whatever passwords you are using whether its a vty password or a username password and or enable secret password .Change the config register back to 0x2102 and then write mem the box and reload. Have never seen the recovery procedures fail. Can you post your exact procedures you are following otherwise I would look over that doc and again follow it step by step .

Hi Glen,

I am sending you the capture text for your ref.

At the rommon prompt try just using "confreg 0x2142 , then reset the box and see what happens. Looking at the post it says its at

0x2141 so this may be the problem.

******** The system will autoboot now ********

config-register = 0x2141

Autobooting using the first file from bootflash.....
