Troubleshooting
The basic idea relies on the following five major steps:
Honeypot detection—The honeypots are first detected via the following steps.
1.
A parent node is set by the AWPP module, by:
–
–
–
Honeypot conviction—When a honeypot is detected, it is placed in a exclusion-list database with its
2.
conviction period to remain on the list. The default is 32 minutes. Other nodes are then attempted as
parents in the following order, falling back to the next, upon failing the current mechanism:
–
–
–
–
Non-honeypot credit—It is often possible that a node is not a really a honeypot, but appears to be
3.
due to some transient backend condition, such as:
–
–
–
Such non-honeypots must be credited properly from their serving times so that a node can come back
to them as soon as possible.
Honeypot expiration—Upon expiration, an exclusion-list node must be removed from the
4.
exclusion-list database and return to normal state for future consideration by AWPP.
Honeypot reporting—Honeypots are reported to the controller via LWAPP mesh neighbor message
5.
to the controller, which shows these on the Bridging Information window. A message is also
displayed the first-time an exclusion-listed neighbor is seen. In subsequent software release, an
SNMP trap will be generated on the controller for this condition so that Cisco WCS can record the
occurrence.

A static IP attempt in CAPWAP module.
A DHCP attempt in the DHCP module.
A CAPWAP attempt to find and connect to a controller fails.
On the same channel.
Across different channels (first with its own bridgegroupname and then with default).
Another cycle, by clearing conviction of all current exclusion-list entries.
Rebooting the AP.
The DHCP server is either not up-and-running yet, has failed temporarily, or requires a reboot.
The WLAN controller is either not up-and-running yet, has failed temporarily, or requires a
reboot.
The Ethernet cable on the RAP was accidentally disconnected.
