Industrial Ethernet Layer 2 Managed Switch – Web Management Manual

3.Redundant Setting

Redundant LAN topology is a structure to provide the link failure recovery and escaping network loops. It allows you to setup the redundant loops for supporting backup connections.

Managed Switch offers redundancy options for various functions, it is a highly reliability device provides the fast error detection and keeps the non-stop connections 24 hours a day, 365 days a year. To manage the Managed Switch for use in redundant network topology, following configuration options are available.

￿Redundant Setting

This function enables you to configure the Switch operation modes.

Ring Pair 1：

Enable／Disabled Ring Pair 1, it consists of port 1 and port 2.

Ring Pair 2：

Enable／Disabled Ring Pair 2. it consists of port 3 and port 4.

Protocol：

Managed Switch supports two kinds of redundant communication – Cyber-Ring and STP (Spanning Tree Protocol). Compare to the Spanning Tree Protocol, Cyber-Ring provides less fault recovery time, reconfiguration time and fault detected time.

Ring Coupling:

If “Primary Switch “ is selected, Switch will be forced as a Master of the topology.
