no mac-security [port {slot/port[/sub-port][-slot/port[/sub-port]][,...]} ] limit-learning [enable]

enable: Limits the MAC learning for the port.
limit-learning max-addrs <1-64000>: Specifies the maximum number of MAC addresses to learn. The default is 1024.
port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}: Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
