Sometimes, I see an unknown ethernet address on my
switch port (Cabletron SmartSwitch6000).
This address is 14:14:14:14:14:14
??!!!!
On my switch port, I have only one PC with one ether card!
and I see this unknown address with the actual one !!!

I have seen in the RFC 1340 but I have found nothing on.

If somebody has a response or a clue, it will be good!

Thank you

This is the virtual MAC-Address of you BPDU ( Bridge Protocol Data Unit )

The BPDU is the internal unit in a bridge or switch to calculate algorithms for the spanning tree protocol and to detect other switches in the connected LAN
Don't worry about this adress ;-))
