Sometimes, I see an unknown ethernet address on my <br />
switch port (Cabletron SmartSwitch6000).<br />
This address is 14:14:14:14:14:14<br />
??!!!!<br />
On my switch port, I have only one PC with one ether card!<br />
and I see this unknown address with the actual one !!!<br />
<br />
I have seen in the RFC 1340 but I have found nothing on.<br />
<br />
If somebody has a response or a clue, it will be good!<br />
<br />
Thank you
