Thanks, Robbie.

I'm interested to know why you think that's a bad idea? - one of the
solutions I was considering is to setup a SPAN port against the uplink on
each switch and use bandwidthd on that.  I have very little network
experience at this level, so I'm likely missing something (and that's the
main reason I decided to ask here as it is very likely others have been
here and learned the lessons).

Thanks.  Definitely an option being considered!

Cheers,
