dot1dStpBridgeForwardDelay {dot1dStp 14}
TimeTicks Read-Write
The value that all bridges use for ForwardDelay when this bridge is acting as the
root. Note that 802.1d/D9 specifies that the range for this parameter is related to
the value of dot1dStpBridgeMaxAge. The granularity of this timer is specified by
802.1d/D9 to be 1 second. An agent may return a badValue error if a set is
attempted to a value which is not a whole number of seconds.
The Forward Delay Time must be at least 4 seconds, and must adhere to the
aforementioned equation involving Max Age Time and Forward Delay Time.
dot1dStpPortTable {dot1dStp 15}
Not-Accessible
A table that contains port-specific information for the Spanning Tree Protocol.
All of the unit’s ports are included in this table, regardless of whether the
Spanning Tree Protocol is currently enabled for the ports.
dot1dStpPortEntry {dot1dStpPortTable 1}

A list of information maintained by every port about the Spanning Tree Protocol
state for that port.
dot1dStpPort {dot1dStpPortEntry 1}
Integer Read-Only
The port number of the port for which this entry contains Spanning Tree Protocol
management information.
dot1dStpPortPriority {dot1dStpPortEntry 2}
Integer Read-Write
The value of the priority field which is contained in the first (in network byte
order) octet of the (2 octet long) Port ID. The other octet of the Port ID is given
