Chapter 2 Fault Descriptions
IDS (Intrusion Detection System) Faults
Radio Role must be
“roleScanner” to support
Frame Monitoring (was
x).
This fault is raised when a radio is
initially configured for Frame
Monitoring (where x is the integer
value of the SNMP OID
cd11IfStationRole from the
CISCO-DOT11-IF-MIB), but
then someone configures the
radio out of scanning-only mode.
As a side effect, this also disables
Frame Monitoring.
When this fault is cleared, the
following message displays:
Radio Role is “roleScanner” and
supports Frame Monitoring.
Radio Mgr > Frame
Monitoring
Review your network to determine
the action necessary to clear the fault
condition.
Although this situation might simply
be that an administrator no longer
needs to monitor or scan a portion of
their site any longer, it could also be
an intruder who has somehow gained
console access to a Scanning AP and
is attempting to “blind” IDS services
for a portion of a site.
TKIP Replay is detected The fault threshold set has been
exceeded.
When this fault is cleared, the
following message displays:
There is no TKIP Replay
detected.
