Profiles > IDS
The IDS profiles configure the AP's Intrusion Detection System features, which detect and disable rogue
APs and other devices that can potentially disrupt network operations. An AP is considered to be a rogue
AP if it is both unauthorized and plugged into the wired side of the network. An AP is considered to be an
interfering AP if it is seen in the RF environment but is not connected to the wired network.
The top-level IDS profile, assigned to an Aruba AP group or AP name, references additional IDS profiles that
are also described in this section. ArubaOS includes predefined top-level IDS profiles that provide different
levels of sensitivity. The following are predefined IDS profiles:
ids-disabled
ids-high-setting
ids-low-setting
ids-medium-setting (the default setting)
You apply the top-level IDS profile to an AP group or specific AP.

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.
This trap refers to the event of the bandwidth rate for a station exceeding a
configured threshold (High watermark). The terms High Watermark and Low
Watermark hold the same meaning as explained above.
This trap refers to the event when the percentage of received and transmitted
frames at low speed (less that 5.5Mbps for 802.11b and less that 24 Mbps for
802.11a) exceeds the configured High Watermark. The terms High Watermark and
Low Watermark hold the same meaning as explained above.
