DESCRIPTION
Use this field to limit the number of (dynamic) MAC addresses that may be learned on a
port. 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 Apply 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 begin configuring this screen afresh.
