Number of
Learned MAC
Addresses
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 five devices’
MAC addresses learned on port 2 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
“16384”. “0” means this feature is disabled.
