OK. I reconfigured dnsmasq so that the switches all get a fixed address, and documented this. I then reset switch02 (the offending one) and went round every board, including toolchain, and everything got its address perfectly. All boards now back online and running health checks in LAVA.

While I was on each board I've also taken their MAC address and documented that (sorry - it's not a completely open document because it contains security information) and as Michael H noted there are indeed one or two pandas with the same MAC address, which means that I can't serve IP addresses from dnsmasq to the toolchain boards, so they're still hardwired.

Hi all,

As part of my investigations into our IP addressing issue, I am going to reboot one of the Cisco switches in the lab. This will mean downtime of maybe a few minutes, and will happen later today. It means that Pandas 05-24, Origens 02-10 and the Toolchain pandas will be unavailable during that time.

Thanks

Dave
