The number of frames discarded by this port due to excessive transit delay
through the bridge. It is incremented by both transparent and source route
bridges.
dot1dBasePortMtuExceededDiscards {dot1dBasePortEntry 5}
Counter Read-Only

incremented by both transparent and source route bridges.
6.2 SPANNING TREE GROUP
dot1dStp {dot1dBridge 2}
dot1dStpProtocolSpecification {dot1dStp 1}
Integer Read-Only
An indication of what version of the Spanning Tree Protocol is being run. The
value decLb100 (2) indicates the DEC LANbridge 100 Spanning Tree protocol.
IEEE 802.1d implementations will return ieee8021d (3). If future versions of the
IEEE Spanning Tree Protocol are released that are incompatible with the current
version a new value will be defined.
Always iee8021d (3).
dot1dStpPriority {dot1dStp 2}
Integer Read-Write
The value of the write-able portion of the Bridge ID, i.e., the first two octets of
the (8 octet long) Bridge ID. The other (last) 6 octets of the Bridge ID are given
by the value of dot1dBaseBridgeAddress.
Any value from 0 to 65535 may be specified.
dot1dStpTimeSinceTopologyChange {dot1dStp 3}
TimeTicks Read-Only
The time (in hundredths of a second) since the last time a topology change was
detected by the bridge entity.
