Bridge MIB
4-3
For example, in the case where multiple ports correspond
one-to-one with multiple X.25 virtual circuits, this value might
identify an (e.g., the first) object instance associated with the X.25
virtual circuit corresponding to this port. For a port which has a
unique value of dot1dBasePortIfIndex, this object can have the
value {0 0}.
Always {0 0}.
dot1dBasePortDelayExceededDiscards {dot1dBasePortEntry 4}
Counter Read-Only
The number of frames discarded by this port due to excessive
transit delay through the bridge.
dot1dBasePortMtuExceededDiscards {dot1dBasePortEntry 5}
Counter Read-Only
The number of frames discarded by this port due to an excessive
size.
4.2 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).
