Bridge MIB
4-5
Port number of this bridge’s current spanning tree root port, or 0, if
this bridge is the current spanning tree root bridge.
dot1dStpMaxAge {dot1dStp 8}
Integer Read-Only
The maximum age of Spanning Tree Protocol 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.
dot1dStpHelloTime {dot1dStp 9}
Integer Read-Only
The amount of time 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, in units of hundredths of a
second. This is the actual value that this bridge is currently using.
dot1dStpHoldTime {dot1dStp 10}
Integer Read-Only
This time value determines the interval length during which no
more than two Configuration bridge PDUs shall be transmitted by
this node, in units of hundredths of a second.
dot1dStpForwardDelay {dot1dStp 11}
Integer Read-Only
This time value, measured in units of hundredths of a second,
controls how fast a port changes its spanning state when moving
towards the Forwarding state. The value determines how long the
port stays in a particular state before moving to the next state. For
example, how long a port stays in the Listening state when moving
from Blocking to Learning. This value is also used, when a
topology change has been detected and is underway, to age all
dynamic entries in the Forwarding Database.
Note: This value is the one that this bridge is currently using, in contrast
to dot1dStpBridgeForwardDelay which is the value that this bridge
