For more information on the mac-age-time command see 'Interface Access and System Information' in the Management and Configuration Guide for your switch. You can set the MAC age out time using the CLI, SNMP, Web, or menu interfaces. The default age time is five minutes.ДЄddresses learned this way appear in the switch and port address tables and age out according to the MAC Age Interval in the System Information configuration screen of the Menu interface or the show system information listing.

Addresses learned in the learn continuous mode will 'age out' and be automatically deleted if they are not used regularly. In this state, the port accepts traffic from any device(s) to which it is connected. Allows the port to learn addresses from the device(s) to which it is connected. On switches covered in this guide, automatically invokes eavesdrop protection, see Eavesdrop Prevention.Д¬ontinuous: (Default): Appears in the factory-default setting or when you execute no port-security. Identifies the method for acquiring authorized addresses. Eavesdrop Prevention should not cause any issues because all valid MAC addresses have been configured. The port is secured by a static MAC address. When Eavesdrop Prevention is disabled, the port transmits packets that have unknown destination addresses. Eavesdrop Prevention may cause difficulties in learning MAC addresses (as with static MAC addresses) and cause serious traffic issues when a MAC ages out. The port is secured MAC addresses age normally. Ports forward traffic with unknown destination addresses normally.Дisabling Eavesdrop Prevention is not applied to the port. The Eavesdrop Prevention option does not apply because port security is disabled. A device must generate traffic before the MAC address is learned and traffic is forwarded to it. The port is secured and only a limited number of static MAC addresses are learned.
