MAC address field

["Helge Kruse" <Helge.Kruse () fortech de>]

I read about the MAC address in
http://en.wikipedia.org/wiki/MAC_address#Address_details. This describes
that the lower two bits of the first MAC byte are reserved. The lower bit is
reserved for non-unicast (a.k.a. as broadcast) and the second for locally
administered addresses.

 

Reading the OUI list at http://standards-oui.ieee.org/oui.txt lists the OUI
"02-60-8C" assigned to 3COM. This does not reflect the definition in the
Wikipedia article. Is this OUI assigned in error? How can this "locally
administered" bit be used?

 

The Wireshark Ethernet dissector shows this as "LG bit: Globally unique
address".

 

Best regards

Helge
