on the smaller switches it is 1 table for the entire switch.
1 other thing to watch is there is not much buffer memory (2Mbyte for
all ports on a 24p 10/100 + 2 SFP unit) - we have some acting as "WAN
edge" routers for 10 and 100 Mbps Ethernet WAN, and tweaking the
buffers to handle GigE -> 10M has some compromises.
