•Priority — Bridge priority is used in selecting the root device,
root port, and designated port. The device with the highest
priority becomes the STP root device. However, if all devices
have the same priority, the device with the lowest MAC address
will then become the root device.
- Default: 32768
- Range: 0-61440, in steps of 4096
- Options: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672,
32768, 36864, 40960, 45056, 49152, 53248, 57344, 61440
•Hello Time — Interval (in seconds) at which the switch
transmits a configuration message.
- Default: 2
- Minimum: 1
- Maximum: The lower of 10 or [(Max. Message Age / 2) -1]
•Maximum Age — The maximum time (in seconds) the switch
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 STP 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. (References to “ports” in this section means
“interfaces,” which includes both ports and trunks.)
- Default: 20
- Minimum: The higher of 6 or [2 x (Hello Time + 1)].
- Maximum: The lower of 40 or [2 x (Forward Delay - 1)]
