So I got a E5810a in and it appeared to be in good shape but it refused to get a DHCP address. I checked it by connecting to a host 1:1 and using the link-local address to log in. There, I found very old firmware, 1.02. I thought yay this must be it. But after setting up a private ftp server and upgrading the firmware from xdevs.com, I had the same issue.
Long story short, my DHCP server is KEA DHCP running on an OPNsense firewall in this lab. I determined that the dhcpoffer was less than the required minimum of 300 bytes for rigid bootp minimum enforcement. So I padded the reservation for this unit with options 58 and 59 with reasonable numbers. This solved the problem. The E5810a accepts the DHCP offer now and works fine.
Thanks to the awesome xDevs site and chat I was able to get this cool GPIB gateway working with dhcp.
