Reading the Event Log
A-3
Each slot transmits BOFL requests via the backplane to the other slots in the
router in order to determine which slots are active. Each slot transmits 16 BOFL
requests per second. The operating system logs the status of each slot as follows:
• If a slot does not hear from a remote slot within 4 seconds (s) (64 BOFL
requests), it logs the state of that slot as “DOWN.”
• If a slot receives some BOFL responses from a remote slot, or does not
receive all that it should have, it logs the state of that slot as “SYNC.”
• If a slot receives all of the necessary BOFL responses from a remote slot that
it previously determined as “DOWN” or “SYNC,” it logs a message stating
that the remote slot is “reconnected” to the backplane.
For example, in Message 40, Slot 3 declares that Slot 2 is back up.
