Description: Gigabit Ethernet Frame Buffer Fullness Alarm.

This alarm is used to inform the user when one or more Gigabit Ethernet Frame buffers are about to or have overflowed. The overflow level is based on the actual input data rate.

'major' when the frame buffer crosses a user specified threshold (apexGbeConfigFrameBufferAlarmThreshold). Cleared when the buffer level drops below the threshold.

'critical' when the frame buffer is completely full and frames are being dropped. Cleared when the overflow condition stops.

A Major alarm, depending on the threshold setting, indicates that the APEX is getting close to overflowing it's internal Gigabit Ethernet frame buffers.

A Critical alarm indicates that the frame buffer levels have overflowed. This will cause loss of packets and may result in tiling and other output anomalies.

What is apexAlarmGbeBufferFullness?

Monitors Gigabit Ethernet frame buffer capacity and raises a major alarm when one or more buffers approach or reach overflow based on the actual incoming data rate. This helps operators detect and respond to input overload conditions before data is lost.

Examples
