Fabric OS Message Reference 685

53-1003140-01

NBFS-1005

Message FSPF experiencing link issues on port <port string> in state <current state name>

(<state change number>).

Message Type LOG

Severity INFO

Probable Cause Indicates that FSPF is experiencing issues with frames on the link leading to unexpected inputs being

sent to the neighbor finite state machine (NBFSM). NBFSM states are as follows:

• 0 - Down

• 1 - Init

• 2 - Database Exchange

• 3 - Database Acknowledge Wait

• 4 - Database Wait

• 5 - Full

If this error occurs repeatedly, then there is a problem running the FSPF exchange and synchronization

protocol between two switches across the identified link.

Recommended

Action

Run the nbrStateShow command to check the neighbor state of the port listed in the message. If it is

Full, then this message can safely be ignored. Otherwise, please check the portStatsShow command to

see if there are errors on the link. If there are errors, consider running the D-Port Diagnostics tests on the

link and/or consider replacing and faulty or bad equipment such as cables or optics.
