With this feature enabled, MAC addresses for the specified interface will not be learned on a data VLAN, and any MAC adress that had been previously learned on a data VLAN will be removed.

To configure this feature on an interface, use the voip-mac-exclusive statement at the [edit switch-options voip interface name] hierarchy level.
