2.5. Bridge Configuration

In Bridge mode the airPoint™ unit acts as a transparent bridge between the Radio and the Ethernet interfaces. The figure below shows the bridge configuration and the bridge forwarding table information. The STP (Spanning Tree Protocol) is disabled by default.

2.6. Configuring Spanning Tree Protocol (STP)

STP is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. For a Layer 2 Ethernet network to function properly, only one active path can exist between any two stations.

STP is disabled by default. The table below lists the default STP settings when the STP is enabled.
