Protocol Enable this parameter to participate in an STA compliant network. The
default is ENABLED.
Priority Set the device priority used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA root
device. However, if all devices have the same priority, the device with the
lowest MAC address will then become the root device. The default is 32768.
Enter a value from 0 - 65535.
Remember that the lower the numeric value, the higher the priority.
Hello Time
(in seconds) Set the time interval at which the root device transmits a configuration
message. The default is 2.
The minimum value is 1.
The maximum value is the lower of 10 or
[(Max. Message Age / 2) -1].
Max Age
(in seconds) Set the maximum time a device can wait without receiving a configuration
message before attempting to reconfigure. All device ports (except for
designated ports) should receive configuration messages at regular intervals.
Any port that ages out STA information (provided in the last configuration
message) becomes the designated port for the attached LAN. If it is a root
port, a new root port is selected from among the device ports attached to the
network. The default is 20.
The minimum value is the higher of 6 or
[2 x (Hello Time + 1)].
The maximum value is the lower of 40 or
[2 x (Forward Delay - 1)].
