- It is a bug ''because of the bug report' ; but there are no workarounds mentioned , neither any fixed versions , then you need to contact Cisco support : https://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html

how many VLAN you have in that switch, and where is the MAC address do you any where in the network as duplicate ?
post the output of this - gi1/0/48
If this is only log you can ignore it, if this performance issue then you need to look deeper, as i mentioned is this only one switch in the network or connected to other part of the network ?
