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

to "16K". "0" means this feature is disabled.
