MAC Address Table

MAC address table configuration controls how NX-OS devices learn and age out MAC addresses. It covers the aging time, system and user-defined MAC address limits, MAC move and threshold notifications, and static MAC address entries that forward to an interface or drop traffic for a given VLAN.
