This is one of my exceptions - you really need 128K MAC's for meto network.

And, for metro network, it may be reasonable to spend time in QA'ing and
configuration and select non-cisco solution - because it is a very big
project. But it is exceptional case.

I just never tried to configure 'traffic-shape' on it, so I do not know. It
is great switch for it's  niche. Metro LAN's is not standard switch niche,
it is very special network. As I said above, non-cisco solution can paid off
for this.
