System Priority:
Each interface is associated with a port (number) in the STP code. And,
each switch has a relative priority and cost that is used to decide what the shortest path is to
forward a packet. The lowest cost path is always used unless the other path is down. If you
have multiple bridges and interfaces then you may need to adjust the priorities to achieve
optimized performance.
The Managed Switch with the lowest priority will be selected as the root bridge. The root
bridge is the
“central” bridge in the spanning tree.
Max Age:
If another switch in the spanning tree does not send out a hello packet for a long
period of time, it is assumed to be disconnected. This timeout is set with:
Hello Time:
Periodically, a hello packet is sent out by the Root Bridge and the Designated
Bridges that are used to communicate information about the topology throughout the entire
Bridged Local Area Network.
Forward Delay:
It is the time spent in each Listening and Learning state before the
Forwarding state is entered. This delay occurs when a new bridge comes onto a busy
network.
Force Version:
Set and show the RSTP protocol to be used. Normal - use RSTP,
Compatible - compatible with STP.
