Chapter 3 Port speed limitation
3.1 Overview of port speed limitation function
SICOM series Industrial Ethernet Switch supports port transmitting rate limitation, services
limitation and broadcast limitation, which all belong to the traffic limitation function.
Support max 26 ports’ speed limitation at the same time.
Support user typing specific limit value
Speed limitation range
The minimum limitation value: 64Kbps;
the max limitation value: 100*100Kbps (100M port)
Speed limitation accuracy

Control Interface: support the speed limitation control by CONSOLE port, Telnet and WEB.
Limitation mode:
Speed limitation is divided into two groups, group 1 and group 2. The message firstly access
group 1 which is specialized in the limitation of service messages and is fixed to all ports.
Group 2 is used to do limitation to other messages and it is also fixed to all ports.
Default configuration:
Service messages: unicast, multicast
Broadcast messages: broadcast, reserved multicast, unknown unicast, unknown multicast.
Support separated limitation of service messages and broadcast messages
Support overall speed limitation for transmitting messages.
Support showing all ports’ speed limitation configuration
Support showing each port’s speed limitation configuration
