Set the priority of the switch.
Priority is an important reference to determine whether the switch will be
selected to work as root bridge, and switch with higher priority will be
selected to work as root bridge under equivalent conditions. The lower
the value, the higher the priority. Priority is 32768 by default.
Set the time interval to 2 seconds by default for the switch to send
BPDU.
Set the maximum survival time of BPDU message when it is stored on
the switch The default is 20 seconds.
Maximum aging time must meet the following requirements:
Maximum aging time ≥ 2 * (Hello Time + 1)
Maximum aging time ≤ 2 * (forwarding delay time – 1)
Set the delay time of port status transition of the switch when a change in
network topology takes place. The default is 15 seconds.
Loopback Detection
Note
When the spanning tree functions are disabled, the loopback detection function, auto
awakening and awakening time interval cannot be set.
When the spanning tree function is enabled and the loopback detection function is
disabled, the auto wake-up function gets invalid. Auto wake-up function can get valid
only when both the STP function and loopback detection function are enabled.
