DESCRIPTION
Select this option to activate this rule.
Enter the number of the port to which this rule is applied.
Enter the VLAN identification number.
Use this field to limit the number of (dynamic) MAC addresses that may
be learned on a port in a specified VLAN. 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 Switch Setup screen. The valid
range is from "0" to "16384". "0" means this feature is disabled.
Click Add to save your changes to the Switch's run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Click Cancel to reset the fields to your previous configuration.
Click Clear to clear the fields to the factory defaults.
This field displays the index number of the rule. Click an index number to
change the settings.
This field displays Yes when the rule is activated and No when is it
deactivated.
This field displays the number of the port to which this rule is applied.
