fnbConnectLeft
Module: CTRON-COMMON-MIB
OID (symbolic): CTRON-COMMON-MIB::fnbConnectLeft
OID (numeric): 1.3.6.1.4.1.52.1.6.1.2.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The Connected Left board (board n + 1) has the following states:
Detached == 1 (Management (only management) detached, read/write). Attached == 2 (Management/AutoMode attached, read/write). Faulted == 3 (Management/AutoMode tried to attach but failed READ ONLY).
What is fnbConnectLeft?
This read-write enumerated integer reports and controls the connection state of the board immediately to the left (board n+1) on the Flexible Network Bus: detached(1) meaning management-only detachment, attached(2) meaning both management and AutoMode are attached, or faulted(3), a read-only state indicating an attach attempt failed. An administrator uses this to manage or diagnose the FNB interconnect between adjacent boards in the chassis. For example, if a neighboring board shows faulted(3) on this object, the admin knows an automatic attach attempt to the left-adjacent board failed and investigates that board's FNB connector or seating.
