NBFSM_System Error Messages NBFSM_System Error Messages NBFSM is a part of the Fabric Shortest Path First (FSPF) protocol that handles a neighboring or adjacent switch's Finite State Machine. Input to FSM is an event that moves a neighboring or adjacent switch (directly connected to the local switch) from one state to another, based on specific events. For example, when two switches are connected to each other using an ISL (interswitch link) cable, they will be in the Init State. After both switches receive HELLO messages, they move to the Database Exchange State, and so on. NBFSM states are Down (0), Init (1), Database Exchange (2), Database Acknowledge Wait (3), Database Wait (4), and Full (5).

NBFSM_System Error Messages
NBFSM is a part of the Fabric Shortest Path First (FSPF) protocol that handles a
neighboring or adjacent switch’s Finite State Machine.
Input to FSM is an event that moves a neighboring or adjacent switch (directly
connected to the local switch) from one state to another, based on specific events.
For example, when two switches are connected to each other using an ISL
(interswitch link) cable, they will be in the Init State. After both switches receive
HELLO messages, they move to the Database Exchange State, and so on.
NBFSM states are Down (0), Init (1), Database Exchange (2), Database
Acknowledge Wait (3), Database Wait (4), and Full (5).
