DESCRIPTION
MAC address learning reduces outgoing broadcast traffic. For MAC address learning to occur
on a port, the port itself must be active with address learning enabled.
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 must wait until one of the
five learned MAC addresses ages 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.
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.
