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.
Table 2-5 Default STP Values
Setting Default Value Range Purpose
Bridge priority 32768 0-65535 A parameter used to identify the
root bridge in a spanning tree
(instance of STP). The bridge
with the lowest value has the
highest priority and is the root
Bridge max age 20 6-40 The interval a bridge will wait for
a hello packet from the root
bridge before initiating a topology
change
Bridge hello time 2 1-10 The interval of time between
each configuration BPDU sent by
the root bridge.
