LABEL	DESCRIPTION
MAC Limit Function	Use this to enable or disable the MAC address limit feature.
Port	This is the port number.
Limit Quantity	Use this field to limit the number of (dynamic) MAC addresses
	that may be learned on a port. For example, if you set this field to
	"5" on port 2, then only the devices with these five learned MAC
	addresses may access port 2 at any one time. A sixth device
	would have to wait until one of the five learned MAC addresses
	aged out. MAC address aging out time can be set in the MAC
	Table Status screen.
Action	Enable the MAC limit function on this port. The MES-2110
	forwards frames whose MAC address(es) is in the MAC address
	table on this port. frames with no matching MAC address(es) are
	dropped.
	Disable the MAC limit function to forwards all frames on this port.
Undo	Click this to load your last saved settings.
Apply	Click Apply to save your changes to the ZyXEL Device’s run-time
	memory. The ZyXEL Device loses these changes if it is turned off
	or loses power, so use the Save Settings link in the navigation
	panel to save your changes to the non-volatile memory.
