15 Frame Retry rate exceeded.
Description: This trap refers to the event when the percentage of received and
transmitted frames with the retry bit crosses the High watermark. This event
can be triggered for an AP, a station or a channel. The two values that should
be configured related to this event are Frame Retry Rate – High Watermark and
Frame Retry Rate –Low watermark. The High Watermark refers to the
percentage threshold which if surpassed triggers the event that causes the
trap to be sent. The Low Watermark refers to the percentage threshold such
that if the retry rate reaches a value lower than this value the event is reset.
What this means is that the trap will be triggered the first time the Frame Retry
rate crosses the High Watermark and then will only be triggered if the Frame
Retry Rate goes under the Low Watermark and then crosses the High
Watermark again. This holds true for all the thresholds explained below as
well.
Priority level: Medium.
16 Frame Bandwidth rate exceeded.
Description: This trap refers to the event of the bandwidth rate for a station

Description: This trap refers to the event when the percentage of received and

24 Mbps for 802.11a) exceeds the configured High Watermark. The terms
High Watermark and Low Watermark hold the same meaning as explained
above.
