Chapter 4 Common Configuration

Spanning-Tree Protocol operation is transparent to end stations, which are unaware
whether they are connected to a single LAN segment or a switched LAN of multiple
segments.
The figure shown below explains the implementation of STP in a network. AP#1 is
physically connected to a switch whilst another 4 access points (AP#2, AP#3, AP#4 and
AP#5) are connected to AP#1 wirelessly. Redundant paths were found in this network,
without enabling STP function, broadcast storm will occur in this network, resulted
duplicated frames to be forwarded.
When STP is enabled, the STP-enabled access points will first try to find the root access
point using the following criteria:
a. use the access point that is configured with the smallest STP priority.
Default priority set in the access points is 32768.
b. If the STP priority values are the same, the access point with smallest MAC
address will be chosen as root.
