Siemens SCALANCE X-300 Series User Manual

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:
Table 8-119 Full wire speed switching
Number of frames At a frame length of (in bytes):
at 100 Mbps at 1000 Mbps
148810 1488095 64
84459 844595 128
45290 452899 256
23496 234962 512
11973 119732 1024
9615 96154 1280
8127 81274 1518
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.
