Product characteristics

Properties of the IE switches
● The Ethernet interfaces support the following modes:
– 10 Mbps and 100 Mbps both in full and half duplex
– 1000 Mbps full duplex
– Autocrossing
– Autopolarity
● Redundancy protocols Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree
Protocol (RSTP) and Spanning Tree Protocol (STP)
This means part of a network can be connected redundantly to a higher-level company
network. The reconfiguration time of the network is in the seconds range and therefore
takes longer than the ring redundancy method.
● Virtual networks (VLAN)
To structure Industrial Ethernet networks with a fast growing number of nodes, a physical
network can be divided into several virtual subnets. Port-based, protocol-based and subnet-
based VLANs are available.
● Load limitation when using multicast protocols, for example video transmission
By learning the multicast sources and destinations (IGMP snooping, IGMP querier), the IE
switches can filter multicast data traffic and limit the load in the network. Multicast and
broadcast data traffic can be limited.
● Time-of-day synchronization
Diagnostics messages (log table entries, e-mails) are given a time stamp. The local time
is uniform throughout the network thanks to synchronization with a SICLOCK time
transmitter or SNTP/NTP/PTP server and therefore makes the identification of diagnostics
messages of several devices easier.
● Link aggregation (IEEE 802.1AX) for bundling ports
● Quality of Service for classification of the network traffic is according to COS (Class of
Service - IEEE 802.11Q) and DSCP (Differentiated Services Code Point - RFC 2474)
Layer 3 functions
The following functions are only available on devices with routing functions:
● Static routing
● OSPF / OSPFv3
● VRRP / VRRPv3
● RIP / RIPng
