3.1. First Time Setup
3.1.1 Overview
The Industrial Ethernet Managed Switch is a configurable device that facilitates the intercon nection of
Ethernet devices on an Ethernet network. This includes computers, operator interfaces, I/O, controllers,
RTUs, PLCs, other switches/hubs or any device that supports the standard IEEE 802.3 protocol.
This switch has all the capabilities of a store and forward Ethernet switch plus advanced management
features such as SNMP, RSTP and port mirroring. This manual details how to configure the various
management parameters in this easy to use switch.
3.1.2 Introduction
To take full advantage of all the features and resources available from the switch, it must be
configured for your network.
The switch implements Rapid Spanning Tree Protocol (RSTP) and Simple Network Man agement
Protocol (SNMP) to provide most of the services offered by the switch. Rapid Spanning Tree Protocol
allows managed switches to communicate with each other to ensure that there exists only one active
route between each pair of network nodes and pro vides automatic failover to the next available
redundant route. A brief explanation of how RSTP works is given in the Spanning Tree section.
The switch is capable of communicating with other SNMP capable devices on the network to
exchange management information. This statistical/derived information from the network is saved
in the Management Information Base (MIB) of the switch. The MIB is divided into several different
information storage groups. These groups will be elaborated in detail in the Management and
SNMP information section of this document. The switch implements Inter net Group Management
Protocol (IGMP) to optimize the flow of multicast traffic on your net work.
The switch supports both port-based and tag-based Virtual LANs for flexible integration with
VLAN-aware networks with support for VLAN-unaware devices.
