This chapter describes messages generated by the sonet subsystem.
Warning
Message: PORT <number> BOUNCING: DOWN/UP PER SECOND - DOWN:<down transitions>, UP:<up transitions>Meaning: The link is rapidly bouncing up and down. The relevant statistics are provided in the message.
Action: First, check links for an intermittent fiber break. Second, check the clocking configuration. The problem may also be due to a hardware fault. If the error persists contact Avici customer support.
