DESCRIPTION
Active
Select this option to activate this rule.
Port
Enter the number of the port to which this rule is applied.
VID
Enter the VLAN identification number.
Limit 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.
Add
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.
Cancel Click
Cancel to reset the fields to your previous configuration.
Clear
Click Clear to reset the fields to the factory defaults.
Index
This field displays the index number of the rule. Click an index number to change
the settings.
