Compex Technologies WPE54 manual Bandwidth STP Cost

Chapter 5 Further Configuration

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.

Once the root access point is determined, the STP algorithm will start to calculate the path cost from each access point to the root access point. Based on the path cost in the following table,

Bandwidth	STP Cost
4Mbps	250
10Mbps	100
16Mbps	62
45Mbps	39
100Mbps	19
155Mbps	14
622Mbps	6
1Gbps	4
10Gbps	2

The path with the smallest cost will be used and extra redundant paths will be disabled.
