It appears that Bill Paul has written some code ("setmac", referred to in the second thread above) that may provide some pointers. Charles -----Original Message----- From: Les Biffle [mailto:les@ns3.safety.net] Sent: Monday, July 10, 2000 7:20 AM To: freebsd-hackers@freebsd.org Subject: Multiple MAC addresses per NIC Hello all, This issue was discussed last year, but I can't find any information on a resolution. We're trying to create a high availability FreeBSD cluster with a standby machine being able to take over for a failed host, and need the standby machine to have its own MAC address, plus the MAC address of the failed host. The NICs we use are RealTek and Intel EtherExpress 100. We find hints in the NIC chip databooks but no information for us mere programmers. So, I have two questions: 1. Does anybody have sample driver code that sets up the multiple hardware address features of these NICs? 2. Does anybody have documentation that could help me create the driver changes? (book, PDF, publication number, anything?) We have tried to get more documentation out of Intel, and the salesmen are willing, but we need a publication number to get anything. They keep giving us the databook, which list pinouts, various electrical specs, and some theory, but it's no programmer reference. Thanks, -Les -- Les Biffle Community Service... Just Say NO!
