Global Policies
Weak WEP
If the AM detects a station or AP encrypting 802.11 frames with weak WEP, a
syslog event is generated if this policy is enabled. The policy is configured as
follows:
Interference Detection
WMS can be used to detect interference near a wireless client station or AP
based on an increase in the Frame Receive Error Rate and Frame
Fragmentation Rate. If this policy is enabled, an increase in the expected rates
will generate a syslog event. The policy is configured as follows:
Interference detection can be tuned using the following options:
z Interference Wait Time
The amount of time an AM inspects traffic to create a baseline for normal
values for retry rate and receive error rate.
z Interference Increase Threshold
The percentage increase in retry rate or receive error rate caused by
interference.
z Interference Increase Time
The amount of time in seconds that the increased rate should be present
before an event is generated.
Statistics Events
WMS can generate events when particular statistics exceed configured
thresholds. Both high and low watermark values can be specified for each
statistic. When the statistic exceeds the high watermark, an event is
(Alcatel) (wms) # global-policy detect-bad-wep { enable | disable }
