Priority [128]
The spanning tree port priority can be set between 0 and 255. The lower
the priority, the greater the probability that the port will be chosen as the
root port.
Fast STP <Disabled>
Toggle between Enabled and Disabled . When the STP is turned on, a
change from link-down to link-up will trigger the STP. The STP will set the
port to the listening state. After the forward delay, the STP will set the port
to the learning state. After another forward delay, the STP will set the port
to the forwarding state. If the forward delay is 15 seconds, the port will take
30 seconds to forward packets. However, when Fast STP is
Enabled on a
port, the port will only take 15 seconds from link-up to the time that it starts
forwarding packets. This is because enabling the Fast STP option will skip
the learning state, jumping directly to the forwarding state from the listening
state.
STP State <Enabled>
The Spanning Tree Protocol state for a selected port can either be Enabled
or Disabled .
