75 – Viewing STP configuration 
The variables listed above are: 
Spanning Tree Enabled (Global): indicates whether STP is enabled or disabled globally 
i.e. if the values is YES, all ports have STP enabled, otherwise, all ports have STP disabled 
 
Spanning Tree Enabled (Ports): indicates which ports have STP enabled – note in the 
figure the ports 9 through 16 are STP enabled, but STP functionality is not enabled – so 
STP will not perform on these ports 
 
Bridge Priority: specifies the switch (bridge) priority value.  This value is used along with 
the switch MAC address to determine which switch in the network is the root device. 
Lower values mean higher priority. Value ranges from 0 to 65535. Default value is 32768 
 
Bridge Forward Delay: indicates the time duration the switch will wait from listening to 
learning states and from learning to forwarding states. The value ranges from 4 to 30 
seconds. Default value is 15 
 
Bridge Hello Time: When the switch is the root device, this is the time between 
messages being transmitted. The value is from 1 to 10 seconds. Default value is 2 seconds 
 
Bridge Max Age: This is the maximum time a message with STP information is allowed 
by the switch before the switch discards the information and updates the address table 
again. Value ranges from 6 to 40 seconds with default value of 20 seconds 
 
Root Port:  indicates the port number, which is elected as the root port of the switch. A 
root port of “0” indicates STP is disabled 
 
Root Path Cost: A path cost is assigned to individual ports for the switch to determine 
which ports are the forwarding points. A higher cost means more loops, a lower cost 
means fewer loops.  More loops equal more traffic and a tree which takes a long time to 
converge – resulting in a slower system
