undo mac-address { dynamic | static } mac-address vlan vlan-id Default An interface is not configured with any MAC address entry. Views Ethernet interface view, aggregate interface view, S-channel interface view Predefined user roles network-admin Parameters dynamic: Specifies dynamic MAC address entries. static: Specifies static MAC address entries. mac-address: Specifies a MAC address in the format of H-H-H. When entering a MAC address, you can omit the leading zeros in each H section. For example, enter f-e2-1 for 000f-00e2-0001. vlan vlan-id: Specifies an existing VLAN to which the specified interface belongs. The value range for the vlan-id argument is 1 to 4094. Usage guidelines Generally, the device automatically builds the MAC address table by learning the source MAC addresses of incoming frames on each interface. To improve the security for an interface, you can manually add the specific MAC address entries to the MAC address table and bind the user device to the interface. Because manually configured static entries have higher priority than dynamically learned entries, using manually configured entries prevents hackers from using forged MAC addresses to steal data. The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC address entries, however, are lost upon reboot regardless of whether you save the configuration.
