Chapter 2 Fault Descriptions
Radio Interface Faults
Not Monitored because:
reason, Ignored
To qualify for Self Healing, an AP
must:
• Enable Radio Monitoring on
both Serving and Non-Serving
channels.
• Be configured with a WDS
that is authenticated with the
WLSE (link status must be
okay too).
The faults will clear when the
WDS/WLSE is reauthenicated and
Radio Monitoring is enabled
correctly.
Number of CCMP
Replay Discarded is
Overloaded.
The fault threshold set for the
overloaded state has been
exceeded.
When the fault is cleared, the
following message displays:
Number of CCMP Replays
Discarded is OK.

Discarded
Verify that the fault threshold is set
correctly.
If the threshold is set correctly,
review your network to determine the
action necessary to clear the fault
condition.
Packet Error is in
Degraded state (error
rate %)
The fault threshold set for the
degraded state has been exceeded.
When this fault is cleared, the
following message displays:
Packet Error is in OK state.

Packet Errors
Verify that the fault threshold is set
correctly.
If the threshold is set correctly,
review your network to determine the
action necessary to clear the fault
condition.
The radio interfaces on the devices
may be very under utilized, which
can trigger the degradation
problem.
For example, if a total of three
packets are sent over the radio, and
two of them are corrupt, the
percentage would be 2/3 = 66%,
and could trigger the alarm.
Remove the alarm from the profile
associated with these devices.
Packet Error is in
Overloaded state (error
rate %)
The fault threshold set for the
overloaded state has been
exceeded.
When this fault is cleared, the
following message displays:
Packet Error is in OK state.
Verify that the fault threshold is set
correctly.
If the threshold is set correctly,
review your network to determine the
action necessary to clear the fault
condition.
Port is administratively
set to down
The port has been set to Down by
the administrator.
When this fault is cleared, the
following message displays: Port is
up

has been deliberately shut down.
