Description
The bridge identifier of the root of the spanning tree
as determined by the STP. This value is used as the
Root Identifier parameter in all configuration BPDUs
originated by this node.
The cost of the path to the root as seen from this bridge.
The port number that offers the lowest cost path from
this bridge to the root bridge.
The maximum age of STP information learned from the
network on any port before it is discarded (in units of
hundredths of a second). This is the actual value that
this bridge is currently using.
The amount of time (in hundredths of a second) between
transmission of configuration BPDUs by this node on
any port when it is the root of the spanning tree. The
default value is 200 (2 seconds).
The time interval (in hundredths of a second), during
which no more than two configuration BPDUs are
transmitted by this node. The default value is 100 (1
second).
The time interval (in hundredths of a second) that
controls how fast a port changes its spanning state
(when moving toward 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 is detected and is under way, to age all
dynamic entries in the Forwarding Database.
This value is the one this bridge is currently using, in
contrast to rcStgBridgeForwardDelay, which is the value
that this bridge and all others use if/when this bridge
becomes the root.
The default value is 1500 (15 seconds).
