Parameter

Description

Code

highBer

Description

High Bit-Error Rate: The local port has detected a bit-error rate in the received signal that is 10-4 or greater.

Entities Affected

  • Ethernet interfaces

  • Fibre channel interfaces

See respective tables below.

Possible Causes

  • Either the fiber link or the optical connection is degraded.

  • There is excessive attenuation of the signal, causing high a signal-to-noise ratio.

Default Severity

Major

Clearing a HighBer Alarm

Note

Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

  1. Retrieve detailed information for the interface to determine whether the value of the Optical Power Rx counter is within the range indicated by the Optical Power Received Minimum Threshold and Optical Power Received Maximum Threshold values.
    show interface name:identifier detail
    Note

    For detailed transceiver specifications, see the BTI7800 Series Hardware Overview and Installation Guide.

  2. Inspect the fiber connection, and ensure that the fiber is intact, thoroughly clean, and correctly connected to the port.
  3. Ensure that no unintentional attenuation has been added to the fiber.
  4. Check for alarms on the interface.
    • If the alarm clears, you have completed this procedure.

    • If the alarm does not clear, contact your next level of support.
