Description
The version of Spanning Tree Protocol to use.
Possible versions include:
• Common Spanning Tree 802.1d - The
standard spanning tree protocol.
• rstp - Rapid spanning tree protocol
802.1w.
The maximum age of Spanning Tree Protocol
information learned from the network on any
port before it is discarded, in milliseconds. This
is the actual value that this device is currently
using.
The amount of time, in milliseconds, between
the transmission of Configuration bridge PDUs
by this node on any port when it is the root of
the spanning tree or trying to become so. This
is the actual value that this device is currently
using.
This speed, in milliseconds, at which a port
changes its spanning state when moving
towards the Forwarding state. The value
determines how long the port stays in each of
the Listening and Learning states, which
precede the Forwarding state. This value is
also used, when a topology change has been
detected and is underway, to age all dynamic
entries in the Forwarding Database.
The maximum amount of time before
Spanning recalculates if there is no change in
network bridging status.
The amount of time between sending
Spanning Tree updates if there are no detected
changes in the overall bridged network
topology.
The amount of time for the device to begin
forwarding packets after recalculating its
Spanning Tree table based on a change in
network topology.
