On the Polycom VVX 411, when connecting a computer using the built-in switch, we've noticed that the phone still "reports" the computer's MAC address even after disconnecting the computer and plugging in another computer. At this point, when looking at the actual access switch to which the phone is connected, it appears that there are three MAC addresses attached to the port (the phone itself and the two computers). This is a problem as we set limits to the number of MAC addresses allowed on the switch ports. Is there a patch, firmware upgrade, etc., that will fix this issue?
What helped us identify the issue is one particular user that changes laptops alot on the 1GB connected eithernet cable kept getting their port disabled at the switch.
