7.1.2 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 re-establishes 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.
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
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.
