Setting Spanning Tree

It is important to avoid point-to-multipoint configurations that will cause bridge loops. A

bridge loop occurs when two parallel network paths are created between any two LANs,

causing packets to be continuously regenerated through both parallel paths. This situation

eventually renders the network unusable due to the excessive traffic that is being generated

by the loop. The AP Spanning Tree function corrects this type of problem by shutting down

the port and possibly shutting down a segment of the network.

Typically, Spanning Tree is disabled when in workgroup bridge mode and enabled in

LAN-to-LAN multipoint bridge mode.
