    I’m receiving this error on any computer plugged into a certain Cisco switch. They’re able to reach the FOG boot menu but won’t go any farther. I receive the error when selecting full host registration, deploy image, debug, etc.

    Like I said, it only happens on a certain switch. Any computer plugged into the unmanaged switch works just fine. They can connect to FOG, register, deploy, and capture images. I’ve tried manually adding the computers to the host list but it doesn’t solve anything.

    Also I wanted to note that I’m using Dnsmasq. Not sure if that affects anything.

    Any ideas? Pretty sure it’s something to do with the switch configuration but I’m not sure what specifically. I’m not very experienced.

    Thanks!

      Check to ensure your switch has spanning tree turned on, AND ensure that you are using one of the fast STP protocols (RSTP, MSTP, Fast-STP, or what ever your switch manufacturer calls it).

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        All the ports are set to spanning tree and portfast. I’m assuming portfast is the fast STP protocol you’re referring to.

          @george1421 Actually nevermind, they’re not. Only 1 port has both enabled. I’ll try that out, thanks!

            @crtech99 Ok I guess we need a bit more info then. What you described seems similar to not having RSTP enabled. But that issue usually appears just after the iPXE boot kernel is transferred to the target computer.

            What error do you see after you reach the FOG iPXE menu? A clear screen shot of error would give an idea to the context of the error. (I’m still thinking spanning tree, especially if you can place an unmanaged switch between the building switch and the pxe booting computer and it works).

            Edit: OK I’m blind I missed your follow up post. Let me know before we proceed.
