Hi,
You have to make sure the machine is sending traffic to the interface so the switch can detect that a new mac address is there and send the snmp trap to the CAM.
If you go to http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_apxb_er.html#wp1009740,
You will find among several event logs, the following:
"Unable to process Out-of-Band login request from [
Cause: connected device [
If this is the error ou are getting, this error message appears when the CAM does not receive appropriate MAC Notification about the client machine. Three common causes for this error condition are:
•
The SNMP trap syntax from the managed switch is not compatible with the SNMP trap syntax on the CAM. (Ensure the syntax/configuration between the switch and the CAM is consistent.)
•The client machine is already connected to a switch port on the Authentication VLAN before the CAM is configured to manage the switch, thus the CAM cannot authenticate the OOB user login request because the CAM is not aware of the client machine connected to the switch port. (Try disconnecting the client machine from the switch port and reconnecting.)
•There are one or more device filters acting upon the client machine MAC address and/or the client machine MAC address appears as an exempt device in the CAM's Certified Devices List.
HTH,
Tiago
