As I mentioned to you at the time, the IT Director might have had very
good reasons for going with Cisco gear. (One of which may or may not be
that they took him on a good golf outing!)
What kind of troubleshooitng facilities exist for your £300 switches?
What's their MTBF? Can they survive a broadcast storm? Can they
PREVENT a broadcast storm?

See? That's probably because the director of IT wanted to use some of
these features.

Most companies will not grant more than read-only access to their onsite
tech, if any access at all. As you mention, these switches can do much
more than just local switching between ports. Untrained people have
been known to mess with stuff they didn't fully understand and cause
network-wide outages. (Trained people too!)
I'm not suggesting you're a cowboy who does any of this, but if you're
interested in helping out your network folks (who are in the US, IIRC)
Cisco offers courses. I'd suggest bringing that up with your manager
and explain that this way, you'd be able to provide faster help when a
problem arises and the boys from the Mothership are still asleep.
