Featured Functions

Redundant Port Status

This field indicates the current status of redundant ports. The state is “Forwarding” for normal transmission, “Blocked” for transmission that is stopped if this port is the backup path, and “Link down” for non-connection.

Ring Coupling

Indicates if the Ring Coupling function is “Enabled” or “Disabled.”

Coupling Port Status

This indicates the current status of coupling ports. The state is “Forwarding” for normal transmission, “Blocked” for transmission that is stopped if this port is the backup path, and “Link down” for non-connection.

The STP/RSTP Concept

Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection from loops. Networks that have a complicated architecture are prone to broadcast storms caused by unintended loops in the network. MOXA EDS-518A’s STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every EDS-518A connected to your network.
