tbNbNoSuccessor8Passes

Module: CXTokenBus-MIB

OID (symbolic): CXTokenBus-MIB::tbNbNoSuccessor8Passes

OID (numeric): 1.3.6.1.4.1.495.2.1.5.9.2.28

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This statistic indicates the number of times this station has gone through the no successor 8 arc in the state machine. This happens when the TBC fails to pass the token and does not succeed in finding a new successor station. The counter is incremented only if the TBC thinks it is not the only active station in the network. A significantly large value in this counter may indicate a 'faulty' transmitter condition in this station.

What is tbNbNoSuccessor8Passes?

Counts times this station went through the 'no successor 8' state-machine arc after failing to pass the token and find a new successor; the counter only increments if the TBC believes it isn't the only active station, and a large value may indicate a faulty transmitter elsewhere on the ring.
