MAC detection problems with L3 OOB

[Isabelle Graham]

We are working on a layer 3, out of band deployment for portions of our network. We had 
set up a fully functional model in our test network using one of our production CAS pairs. 
We recently moved the CAS pair from the test CAM back to the production CAM and added the 
port and switch profiles, as well as the production switch (which was also used in 
testing). Since this migration none of the devices on CCA controlled ports are showing up 
in the Discovered Clients table, the Certified Devices table nor the Online Users table. 
As a result, the users could not be decertified and were allowed constant access. We 
double checked the configuration and tried removing the switch, manually stetting the 
VLANs for those ports to the in band VLAN, then re-adding the switch and converting the 
users to out of band again through the web interface on the production CAM, but the 
problem persists. When in the authentication VLAN, the client and the web based login page 
give an error to the effect that the MAC address of the device cannot be found. Has anyone 
run across this?
