DESCRIPTION
Use the drop-down list boxes to select an DSL port on a line card for which you
want to configure the MAC count limit.
Click Load to display the port's current settings.
Select the check box to activate the MAC count limit on the specified DSL port.
You can only enable the MAC count filter on DSL ports that do not have the MAC
filter enabled.
Specify how many MAC addresses the system can dynamically learn on this port.
The range is 1~128.
For example, if you are configuring port 2 and you set this field to "5", then only five
devices with dynamically 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 ages out.
Click Apply to save the changes in this screen to the system's volatile memory.
The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your
changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring the screen again.
