Select Enable/Disable STP function globally on the switch.
Select the desired STP version on the switch.
 STP: Spanning Tree Protocol.
 RSTP: Rapid Spanning Tree Protocol.
 MSTP: Multiple Spanning Tree Protocol.
Enter a value from 0 to 61440 to specify the priority of the switch for
comparison in the CIST. CIST priority is an important criterion on
determining the root bridge. In the same condition, the switch with the
highest priority will be chosen as the root bridge. The lower value has
the higher priority. The default value is 32768 and should be exact
divisor of 4096.
Enter a value from 1 to 10 in seconds to specify the interval to send
BPDU packets. It is used to test the links. 2*(Hello Time + 1) ≤ Max
Age. The default value is 2 seconds.
Enter a value from 6 to 40 in seconds to specify the maximum time the
switch can wait without receiving a BPDU before attempting to
reconfigure. The default value is 20 seconds.
Enter a value from 4 to 30 in seconds to specify the time for the port to
transit its state after the network topology is changed. 2*(Forward
Delay-1) ≥ Max Age. The default value is 15 seconds.
Enter a value from 1 to 20 to set the maximum number of BPDU
packets transmitted per Hello Time interval. The default value is 5pps.
Enter a value from 1 to 40 to set the maximum number of hops that
occur in a specific region before the BPDU is discarded. The default
value is 20 hops.
