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-510A’s STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every EDS-510A connected to your network.

Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE Std 802.1w-2001. RSTP provides the following benefits:

yThe topology of a bridged network will be determined much more quickly compared to STP.

yRSTP is backward compatible with STP, making it relatively easy to deploy. For example:

¾Defaults to sending 802.1D style BPDUs if packets with this format are received.

¾STP (802.1D) and RSTP (802.1w) can operate on different ports of the same EDS-510A. This feature is particularly helpful when EDS-510A ports connect to older equipment, such as legacy switches.

You get essentially the same functionality with RSTP and STP. To see how the two systems differ, see the Differences between RSTP and STP section in this chapter.
