Another unique difference in the 3750 is the egress queue capabilities.
Each intf provides 4 queues, one of which can be configured as a
priority queue.  The other 3 can be configured to shape (sets a
guaranteed and a max) or share (sets a min, can burst to available bw).
Finally, you can port limit to a specified rate.  This allows you to
rate limit by traffic type and then apply an aggregate to the port.

At layer 3?

We have plenty of problems on the optical interfaces and TAC has not 
been able to explain why. Strangely enough, the MORE features we turn 
on, the better they are. The more caching we turn off, the better things


We think its a software maturity issue mostly.
