I have a 3825 that is supposed to be in ROMMON mode (according to Cisco documentation), but, I'm not getting the rommon1> symbol, just random characters after hitting the Enter key.
The 'SYS' led on the front panel is flashing green.
Just a suggestion, but the symptoms you describe suggest that it is possibly a problem with your terminal/console session settings?
If the console session settings are different to that what is configured on your network device, then random characters do appear.
Try changing your baud setting to 9600-8-N-1, if this fails gradually increase the speed.
Yes, this is the setting I'm using. I was using this setting when I started having the problems I'm experiencing now. I will try increasing the rate as suggested...
When you make the change on the terminal setting do you disconnect and reconnect each time? I have a USB Console cable, and have to connect and reconnect everytime the session is interupted.
Also have you tried a different console cable?
Is this the first time you attempted to connect to the router via console? curious as to why you think it should be in rommon>
Try reload the router whilst connected via the console with the default baud settings and see if see any messages on the console during boot.
The console cable is fine. When I initially booted the router, it was in rommon mode as the image wouldn't load. I tried transferring an image via tftp, but, kept getting errors. As it's been a few weeks, I do not remember the command I typed that brought the router to the current state.
According to the Cisco documentation, I should be in rommon mode as the 'SYS' led on the front panel is flashing green.
if your stuck rommon and you need to load an image here's the recovery procedure.
if you have an image on the flash card you can always try a manual boot via rommon
boot slot0:(image name)
just try just hitting i from the rommon prompt
No, neither suggestion works. When I hit i (or enter), I just get random characters (i.e.![fYd) whenever I hit any key.
As stated before, I'm not in rommon mode...I'm stuck in some other mode that I cannot get out of. As mentioned before, the 'SYS' led is flashing green on the front panel...this is the only fault indication I'm receiving.
Hi Chris, what image were you attempting to tftp at the time when you starting experiencing these issues?
Was it the IOS Software, or actual IOS ROMMON that was attempted?
If you attempted to upgrade the ROMMON and was successful, then the router will be reloaded automatically and either boot back into ROMMON or load the IOS depending on the conf-reg.
Well, this router already had an image before I attempted to configure this a few weeks ago, but, the image wouldn't load properly and I was forced into rommon. While in rommon, I attempted to tftp a known good image (c3825-advipservicesk9-mz.124-6.T7.bin, 35,859 KB), but, I was receiving a byte size error (or something to this affect...don't remember the exact error). I then made a change, but, honestly I don't remember what I did. I didn't make a conf-reg change, but, now, I cannot modify anything, so, I'm not sure what mode I'm in or how to change itâ¦
