The 4948 isn't fundamentally new... Hardware-wise, it's just a
Catalyst 4500 with a 48-port 10/100/1000 blade and the switching
engine from the Sup5, in a nice 1RU package.

The Sup5 switching engine is 48 Gbps (96G marketing), which means
you get 48 ports non-blocking on the 4948. When comparing it to
the 3750G-48, it's worth noting that the 4948 isn't a 48+4 port
switch. (Only 48 of the 52 ports can be active at the same time).

The 4948 runs the same software as the 4500 Sup2+/3/4/5, which
also means you get the same features. For example, the 4948 does
VRF Lite, which the 3750 *still* doesn't support.
