Cut‐Through, as soon as the switch receive a frame header, it is immediately forwarded without
any error checking and processing; in Store‐and‐Forward, after receiving and storing the
complete frame, error checking is conducted before forwarding. Store‐and‐forward is most widely
used switching technology and it is also adopted by SICOM3004/SICOM3006.
VLAN
VLAN will divide a network into multiple logical networks. Data packets cannot be transmitted
between different VLANs so as to control the broadcast domain and segment flow and improve
the network performance, security and manageability. SICOM3004/SICOM3006 series supports
IEEE802.1q VLAN tag. It can be divided into up to 4094 VLANs based on ports. The VLAN division
can be realized via WEB, CLI. VLAN Tag packet is transmitted transparently.
QoS
function
IEEE 802.1p is the most widely used priority solution in LAN environment.
SICOM3004/SICOM3006 series supports 802.1p standard, as well as IP TOS and DSCP priority
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
function can be used to do port‐based priority configuration. This configuration only affects the
data packets without priorities in the ports. Each port of SICOM3004/SICOM3006 support 4‐level
priority configuration (highest, high, low, lowest).
Port
Trunking
SICOM3004/SICOM3006 series industrial Ethernet switch can aggregate several physical ports
into a logical port, then these ports have same rate, duplex mode and VLAN ID. Port Trunking can
be configured in a single switch with max 4 Port Trunking groups. This function can reduce the
network traffic congestion and enhance fault‐tolerance performance.
Port
mirroring
(Port
sniffing)
Be capable of mirroring the data packets in a port to another port for real time monitoring the
communication data.
Configure
Port
Working
Modes
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
