Parameters
anomaly-detection [options]
(enable|filter-ageout)
Configures parameters related to the detection of anomalous frames on the
RF network.
• all – Enables anomalous frames.
• bad-essid-frame <1-10> – Enables an AP detector to find frames with
bad ESSIDs.
• beacon-broadcast-essid – Enables an AP detector to find beacons with
broadcast ESSIDs.
• invalid-8021x-frame – Detects invalid 802.1x frames.
• invalid-frame-length – Detects invalid frame lengths.
• invalid-frame-type – Detects invalid frame types.
• multicast-source – Broadcast or multicast source.
• non-changing-wep-iv –Detects frames with non-changing WEP IV.
• null-destination – All zero's addess.
• same-source-destination – Identical source and destination addresses.
• tkip-countermeasures – Filters mobile units that cause tkip
countermeasures.
• unencrypted-traffic – Detects the presence of unencrypted-traffic .
• weak-wep-iv – Uses weak wep sequence numbers.
• enable – Enables monitoring and filtering.
• filter-ageout – Sets the number of seconds mobile units must be
filtered.
detect-window<5-300> Sets the number of seconds for gathering information for analysis. All the
thresholds are a function of this window size.
