How do you log in now? Through the management-webinterface? Can you see
the running config, and see if there are any "access-class" defined in
you "line vty" config that would deny you access?

I might also be "management-interface"-related. The IGESM switches we
use (mainly IBM) mostly only accept connections to the interface Vlan
marked with the "management" command. (Btw: Changing the management
interface is a little unintuitive, but well explained in the docs.)
