Store and Forward
All data telegrams received by the switch are saved and
their validity checked. Invalid or faulty data packets
(> 1522 bytes or CRC errors) and fragments
(< 64 bytes) are rejected. Valid data telegrams are
forwarded by the switch. The switch always forwards
the data using the data transmission speed that is used
in the destination network segment.
Multi-Address Function
The switch independently learns the addresses for
termination devices, which are connected via a port, by
evaluating the source addresses in the data telegrams.
Only packets with unknown addresses, with a source
address of this port or with a multicast/broadcast
address in the destination address field are forwarded
via the corresponding port. The switch can store
addresses in its address table with an aging time of
5 minutes. This is important when more than one
termination device is connected to one or more ports. In
this way, several independent subnetworks can be
connected to one switch.
Quality of Service (QoS): IEEE 802.1P/Q
The FL SWITCH SFN… switches are capable of
reading Ethernet packets that have already been
assigned a priority level by a managed switch. In cases
of heavy traffic, packets with a priority level between 4
and 7 are considered high priority and processed
before packets with a priority level between 0 and 3.
After prioritization the packets are forwarded without
modification.
Switching Characteristics
A restart deletes the entire address table.
