I think there are different levels of "managed" switches. This is no
standard definition for this term. There are those (managed) switches
which have things like MIBs and other diags built in (e.g. a local CPU,
perhaps an out of band network, a command line interface, etc.) and
others with a higher level of functionality which includes embedded SM
and additional management appplications support. The latter "class" can
be turned into the former class by disabling the SM.

I don't think so but I may be wrong. I think this is a CPU less
unmanaged switch.
