So what is its "suitable role"?  Paperweight?

Don't confuse the 2948G (which is a decent L2 switch) with the 2948G-L3
(which is neither a usable L2 switch, nor anything useful on L3).

We had *so* much trouble with the 2948G-L3, it's absolutely inbelievable.

The most grave issues are "regular complete lockup of the port ASICs" 
(meaning "no packets go in and out anymore", production network dead, not
fixed even though a case was open for over a year) and "if the L3 ACLs on
the GigE ports exceed a given length, they are silently (!!) deactivated,
leaving the network wide open".

The unit was hardware-RMAed twice, so it's not a hardware fault.  

The box's design is fundamentally broken - there is a good reason why the
8500 series were discontinued pretty quickly.  The 2948G-L3 is just a
fixed-config 8500.
