Question
How to troubleshoot functionality issues with a proximity sensor configured to work with SWC 6.1 endpoints?

Answer
 

Follow the steps below to troubleshoot this issue: Check the proximity sensors default walk away and walk up keys configuration settings in the GUI of the proximity firmware and make sure the key settings are as follows:
• Walk away [Ctrl + End]
• Walkup [Ctrl + Home] Make sure that values for walk away and walk up keys are same in SWC client and server registry keys as below:
• [HKLM\Software\Symantec\Workspace Corporate]
• WalkawayKeys=DWORD:00040023
• WalkupKeys=DWORD:00040024  Un-plug and re-plug the proximity sensor to check if the issue resolves.  Download and install the latest firmware. 

If the steps 1-4 do not resolve the issue, then contact the device vendor.
