Chapter 2 Fault Descriptions
WLSE Faults
Duplicate IP Detection During discovery, an AP with a
duplicate IP is found and placed in
the Duplicate IP folder under
Devices > Managed >
Manage/Unmanage.
This folder contains access points
that are in the pending state.
A device becomes pending and is
placed in this folder when:
• The same IP address is
assigned to more than one
access point.
• An access point’s IP address
changes.
• You replace a managed access
point.
The IP address shown for a device
in this folder is the last known
address for the device, before the
address change occurred.

For information on how to move devices
from the Duplicate IP folder, see the topic:
Handling Duplicate IP Addresses on Access
Points in the Managing Devices chapter of
the User Guide for the CiscoWorks Wireless
LAN Solution Engine, 2.13. or in the online
help.
Fault Engine is
overloaded with
excessive polling.
The WLSE fault engine is
overloaded due a large number of
fault policy and threshold polling
occurring at one time. This
generally occurs when the WLSE
is configured to monitor large
number of fault policies and
thresholds on large number of
devices.
This fault will clear when the
polling rate drops below the
internally set threshold.
Not applicable.
• Make sure the WLSE has connectivity
to the network.
• Reduce the amount of fault polling by
disabling certain policies and
thresholds.
Lost connectivity with
router.
The WLSE is unable to ping the
default router.
Not applicable. Make sure that:
• Connectivity from the WLSE to the
gateway router is okay.
• The gateway router is functioning
properly.
Lost connectivity with
standby on ip_address.
The standby WLSE indicated by
the IP address is down.
Not applicable. Make sure that:
• The standby WLSE is up and running.
• The standby WLSE is network
accessible.
• Redundancy has been correctly setup
on the Active WLSE.
