Hi group,

I was challenged by a customer that that in a secnario of two switch
connected by full duplex Fast Ethernet trunk, he said this trunk can always
got 100 M traffic for the case that all ports are connected by host and
each generates substantial of traffic.

Just want to confirm that whether this is true? or the traffic is limited
to the back plane of the switch? If that trunk is in half duplex, am I just
divid the through by half?

Also, peoples always mention the (pps) to sizing a switch, what does this
(packet per second) mentioning? does it mentioning the performance of
pakect forwarding rate at 64 byte or 1500 byte? or the pps should varies in
different packet size?

Thx,
BBD (Big Black Dog)
