Configuration
Auto configured (auto-negotiation) or manually setting of speed and duplex of individual TX port,
by DIP-switches.
Port mirror function is possible to set with DIP-switch. With the port mirror function active
the switch will copy all outgoing traffic to port 1. This can be used to monitor all traffic going
out from the switch. Packets may be discarded if the total throughput exceeds the port speed
of port 1.
