QoSfunction
IEEE 802.1p is the most widely used priority solution in LAN environment.
SICOM3004/SICOM3006series supports 802.1p standard, as well asIPTOSandDSCPpriority
configurations. When the terminal connected to SICOM3004/SICOM3006 doesn’t support these
three priorities and user wants to set different priorities to services in different ports, QoS

ConfigurePortWorkingModes
SICOM3004/SICOM3006 series is able to configure the working mode of all ports through
network management: self adaptive, 10M/half‐duplex, 100M/half‐duplex, 10M/full‐duplex,
100M/full‐duplex,etc
