Message-ID: Summary: Where is it stated that the above *must hold? Keywords: Ethernet addresses uniqueness Sender: news@bnrgate.bnr.ca (USENET News System) Organization: Bell-Northern Research, Ltd. Ottawa Ontario CANADA Date: 4 Oct 90 18:14:00 GMT In trying to debug a problem we are having here with our file server with 2 ethernet boards connected to 2 *different* subnets on the same network, our vendor eluded to us that the 2 ethernet cards assume the *same* Ethernet address, obtained from the primary ethernet board. Of course, warning bells are going of here. Now I've been searching the RFC and IEEE docs and I cannot find any documentation that sort of says that Ethernet Addresses are assigned to Ethernet boards, not hosts. Anyone have an idea where it might be. I cannot go back to the vendor and say " .... well everyone *knows* that ethernet addresses *must* be unique..." -derick- -- #include Derick Linegar, Internet Systems 4P27, Bell-Northern Research BITNET: LINEGAR@BNR.ca P.O.
