Hi.. just needed a bit of advice on following;
1 have 2960S and 3560 series of switches both having same problem. they boot up normally but after some time they hang up on all management communications. they do not respond to any Serial Port communication, i also have tried to change the baud rate to many settings but still the problem is same. Output from 2960S is below

Deal ALL,
I really need the solution on this matter. please some one help me on this..........

 

Hi

What have you tried so far to resolve this issue?

 

Also might be worth posting your config file

 

thanks for your reply. I have tried to change the baud rate from terminal emulator of windows and have tried to reboot switches but that is also not working. Then i tried to break the boot sequence still the result is same. I am very much confused on this as the switches are not accepting any type of key stroke in hyperterminal and putty. i have tried both of these tools with various baud rates.

 

there is no config file. i mean there is no configuration change, the switches were working in flat configurations and now they have stopped responding. 2960S is not even working as flat switch and 3560 is working as flat switch but not as a layer three switch.

 

Might be worth trying a IOS recovery

Obviously this needs to be done with care, and if it breaks it then I cannot accept responsibility (have to say that in case of lawyers lol), however having said that ive never had an issue reflashing a switch, well been quite a while since ive needed too in fairness.

 

If you're trying to interrupt the boot sequence but your switch isn't responding to keystrokes, one method that has worked for me in the past is to change your terminal client settings to 1200/N81 or 2400/N81 baud with no flow control. While powering on the switch, hold down your space bar, and keep holding it for 20-30 seconds straight - holding the space bar at that baud rate tricks the switch into hearing a BREAK signal. Then switch your terminal client back to 9600/N81 with no flow control (or whatever baud rate your console port is set to), and you should be good to go.

Be SURE that you've got it set to No parity, 8 data bits, 1 stop bit and No flow control. This is by far the most common error I've seen.
