8.1.2 STP Bridge
Spanning-Tree Protocol defines a tree that spans all switches in an extended
network. It forces certain redundant data paths into a standby (blocked) state.
If one network segment in the Spanning-Tree Protocol becomes unreachable,
or if Spanning-Tree Protocol costs change, the spanning-tree algorithm
reconfigures the spanning-tree topology and reestablishes the link by
activating the standby path.
Spanning-Tree Protocol operation is transparent to end stations, which are
unaware whether they are connected to a single LAN segment or a switched
LAN of multiple segments.
This section shows how configuration is done in Spanning Tree parameters.
Description of parameters
STP State
When STP is enabled, it will dynamically detect
network looping owing to mis-configuration of the
network topology. The redundant connectors will be
disabled to avoid looping of packets. Looping would
often result in flooding of broadcast packets, halting
the normal traffic.
Root Priority
(from 0 to 65535)
The priority of the switch is currently acting as the
root. The bridge with the lowest value has the highest
Spanning Tree priority level and is related as the
root.
