Description: Denotes the connection status of the left attach circuitry for a particular FNB ring path attachment on this Token Ring oard.

What is ctronMultiFnbConnectLeft?

Reports the connection status of the left-side attach circuitry for one specific FNB ring path attachment on a multi-ring Token Ring board, with values other(1), detached(2), attached(3), or faulted(4). Admins read this per ring-path attachment, rather than per board, to isolate which of the board's multiple FNB rings has a connectivity problem on its left side. ctronMultiFnbConnectLeft reading faulted(4) for ring path 2 on a given board, while ring path 1 reads attached(3), narrows the fault down to that specific ring attachment.
