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 “16K”. “0” means this feature is disabled.

Add

Click this to create a new entry or to update an existing one.

This saves 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.

Active

This field displays Yes when the rule is activated and No when is it deactivated.

Port

This field displays the number of the port to which this rule is applied.

VID
