Note
The IE Switches X-300 support full wire speed switching complying with IEEE 802.3 on all
ports.
The number of packets depends on the packet length according to the IEEE802.3 standard:

Note
The following applies to IE Switches X-300:
The number of IE Switches X-300 connected in a line influences the frame propagation time.
When a frame passes through an IE Switch X-300, it is delayed by the Store&Forward
function of the IE Switch X-300
•
with a 64 byte frame length by approx. 10 microseconds (at 100 Mbps)
•
with a 1500 byte frame length by approx. 130 microseconds (at 100 Mbps)
This means that the more IE Switch X-300 devices the frame passes through, the longer the
frame delay.
