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.
