LABEL DESCRIPTION
Active Select this option to activate this rule.
Port Enter the number of the port to which this rule is applied. In stacking mode, the first box field is
the slot ID and the second field is the port number.
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 "32K". "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.
