mat8iou - Thanks for posting your question on the forum!
I really do not see where the process may have gone wrong. I'm afraid the only option here is to console into the switch and take a look at what the configuration looks like. Is it still able to switch traffic? Please do not hesitate to let us know if you have any questions once you are able to console into the device.
Thanks for the suggestions.
I left using the console as a last resort, as I was trying to locate a serial cable adaptor to use it.
Anyway - I can connect fine with the console. From there, I reverted back to the backup version & everything worked fine.
Tried upgrading again & exactly the same thing happened.
After that, I tried upgrading by major version - it worked fine up to 14.01.00.E (original was 10.03.00.E). If I go any higher than that, I get the same problem that I can no longer log in, although the console doesn't seem to show anything untoward happening when the device reboots - it is still loading the firmware normally & registering when a cable is connected to any of the ports etc. I've tried a few higher versions though & in none of the cases will it let me log into the web interface.
mat8iou - I had a couple of questions based on the issue you were describing:
- What bootcode are you running on the 1524ST? This can be seen in the "show version' output.
- If you are able to, could you post the output to "show run" using your console connection while the 'bad' code is loaded?
Thanks again for the suggestions.
After a bit of playing about, I seem to have managed to get it to work properly on the new firmware. The problem seemed to be that it was losing all the VLAN information, along with disabling the Web interface, which was why I was struggling to log into it. After re-enabling these from the console, it appears to be working properly now.
