Cisco Cisco 4404 Wireless LAN Controller Technical References

This section provides debugging tips for specific features.

CLI commands and key sections of the debugging script are highlighted in bold. 

Mobility hand off and mobility directory debug commands display the guest-tunnel or AnchorExport 
debugging information in addition to the traditional mobility debugging information.

You will see mobility exchanges [MobileAnchorExport messages (on Foreign) & 
MobileAnchorExportAck (on Anchor)] when enabling mobility hand off and mobility directory debugs.

Debugging guest tunneling and the Ethernet over IP are both included in the regular mobility debugs:

debug mac addr <client mac address>

debug mobility handoff enable

debug mobility directory enable

debug dhcp packet enable

debug pem state enable

debug pem events enable

debug dot11 mobile enable

debug dot11 state enable

While the data source port is being diagnosed, look for UDP packets with Source/Destination 
Port=16666. Any EoIP packets can be filtered by using the display filter etherip in the capture taken.
