Address
Learning
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.
Limited
Number of
Learned MAC
Address
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 “8192”. “0”
means this feature is disabled.
Apply 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.
Cancel Click Cancel to begin configuring this screen afresh.
