When a static MAC entry is configured and then the same MAC is learned on a different port, The switch logs the source MAC address, the received port number, and the VLAN name learned for the duplicate MAC. This event occurs when the static-mac-move configuration is enabled in a switch.
Check the pre-existing static MAC entry information on the switch and verify that the static MAC entry is configured with the right port information. If the static MAC is configured for the correct port, this event might indicate MAC movement from one port to the other port. This event might also indicate a network security attack using bogus packets with the same MAC address dynamically learned on the additional port.
Notice
MAC Learning packet with source MAC %mac% is detected on port %port% and VLAN %vlan% which conflicts the pre-existing static MAC entry
