| [HELP] Cisco 1800 garbled output in putty Hi,
I've got hold of a Cisco series 1800, I was trying to reset the password
When I typed the wrong thing while at router# and now the whole
Console output into putty is in random characters, it's all garbled basically.
Is there any way I can rescue this or is it a write off?
Thanks. |
|
| Your terminal settings set to 9600-8-n-1?
What 'wrong thing' did you type into this thing, just out of curiousity?
Unless you're in config mode (ie. config t) there's not much to screw up
in normal user mode short of a erase flash / reload.
Regards |
|
| I typed confreg 0c2142 but meant to type confreg 0x2142
As soon as I put the whole output in putty went to crap and was all garbled.
I've double checked the putty comms config and it's all fine.
Am just confused now!
Any ideas?
Cheers. |

Okay, so you were messing with the config register -- I'd DEFINATELY get that back to 0x2142 or whatever it was before.
Config register is a rather arcane bit of config for Cisco devices, and I tend to NOT touch it as much as possible.
Regards |

| Yeah I was following steps to change password but made that typo.
Problem now is I can not read the output to do anything at all with it.
It seems to boot up ok and LEDs settle as normal but as I said hole output is garbled can't even access with sdm because it needs reprogramming.
Is there anything at all I can do? |

Have you tried breaking into ROMMON to reset the conf reg? |

I've tried exit, reload and disable to get out of it and even confreg 0x2142 which i meant to type first time round but nothing works.
is there a way of restoring the software onto the card without actually doing it through the router itself?
cheers. |

kudos:1 | I read your 'router>#' as being in enabled mode in IOS, not ROMMON.
With everything flashing correctly but garbled output I'd still want to double-check the console speed. You've definitely tried all the variations of console speed in Putty as mentioned in »www.cisco.com/en/US/products/hw/···3f.shtml ? |
|
| Yes you were right i was in enabled mode, and changing to 19200 speed sorted the problem, thanks! initially the standard 9600 was working fine but im guessing my typo changed something.
All im trying to do anyway is reset it to factory so i can access it with sdm over the network then configure it how i need it.
is there a safe way of doing this? ive tried couple of solutions of the internet but none seemed to work.
Anyway, thanks again! |
|
| This is how Cisco instructs you to do it.

A search of CCO should help if this document isn't enough. |

| Great, thanks. |
