I was in need of a new IOS for the 3550 multi layer switch. So I took the newest IOS and tested it. Apparently this new IOS doesn't work as it supposed to be doing.

After uploading the new IOS (c3550-ipbasek9-mz.122-44.SE.bin) and deleted the configuration and the vlan.dat (don't you always forget that one) I rebooted the switch. It just comes up, no worries here.

After configuring the switch it can be used like a charm. The problem start after the next reboot. It walks through the POST and the IOS startup, the hardware check and posts the message. "Press RETURN to get started".

Once you press enter it will start generating a RSA key. This is the part it freezes. No crash, just freeze. From this point on, no reload seems to help...

This happens every time you want to configure your switch after using the new IOS.

Also the command " ip tacacs source-interface vlan" isn't understood anymore...

My opion:     a crappy IOS.

The previous IOS seems to be running just fine. (c3550-ipbasek9-mz.122-25.SEE4.bin)
