    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

is it a bug?Any workaround for this ?

 

   - 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 supporthttps://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html

are you running the firmware version mentioned in the bug ? try reload and switch and observe.

is this effecting the Live traffic, then reason the SMB tac for the fix.

3.2.0.89 version

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 ?
