      Hello,

      I have a Problem regarding Multicast.

      We are trying to change our imaging-system from Timago to FOG, because we want to save the license costs.

      We are an IT-service-provider at various schools. This system is already running at another school.

      We have around 300 clients in different groups on which the image must be distributed.

      After testing the Roll-out of a few clients via Unicast, which worked perfectly fine, we tested multicast. Everything seemed normal, until the clients just stopped downloading.

      The multicast.log just shows, that we have an Task running. We stopped the task after a while, because nothing was happening.

      As you can see, the Task is running into a lot of Timeouts.

      The first thing I thought of was that this is a network problem, a wrong multicast configuration on the switches. IGMP snooping is on every switch enabled, we configured one switch as the IGMP Proxy. This configuration is mostly identical to a working multicast-configuration of another school.

      As of now, i am at end of my wisdom.

      Best regards

        @george1421 We have 3 switches between the computers and the FOG-server.

        The problem is resolved!

        Our Solution:
        The WebGUI from the switch showed the options in the IGMP Snooping as enabled, in the config-file some of the needed options were disabled. After enabling them in the file and uploading that we tried another mutlicast task.

        The timeouts still are in the multicast.log.udpcast.x, but the task completes successfully.

          I can tell you that multicasting is a beast onto it’s one. 90% of the problems are infrastructure and configuration with the rest something else (most not related to FOG).

          IGMP Snooping needs to be enabled on all network switches and assigned on the VLANs where the multicasts would occur. If your target computers are on different subnets than your FOG server then you will need to enable the igmp proxy service on your VLAN routers. I would suggest that you not try to multicast across a WAN link.

          When multicasting multiple systems the slowest system controls the speed of imaging. The target system image is sent out one block at a time. All clients must acknowledge the block before the next block is sent out by the FOG server (or any multicast imaging server). If not all of the clients respond with an ack to the FOG server the entire block must be restransmitted to all computers. If a client disappears, after a time it will be dropped from the multicast server and the rest will continue to image.

          With the number of retransmits it makes me think you have a networking issue.

          Will you tell us a bit more about this fog server and your environment?

          1. Describe the fog server’s hardware
          2. How many computers that have the fog client installed is talking to this FOG server?
          3. How is the FOG server connected to your network? Is it via a single 1GbE link, 10GbE link, etc??
          4. What is your switch infrastructure?
          5. When you get these timeouts how many target computers are you trying to image at one time?
          6. If you move (as a test) computers to the same subnet as the FOG server, do you have similar results when you send out a multicast?
          7. Does electrical distance from the FOG server impact your ability to multicast (i.e. multicasting works in the building where the fog server is, but not in the building at the far end of your campus?)

          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!

            Thank you for your fast reply.

            I do think that there is one option in our configuration wrong, but i just don´t know where. IGMP Snooping is configured on all switches and the VLANs are correctly assigned. On our Core-Switch (also our router) we have the IGMP Proxy enabled for the right VLANs. The multicast shouldn´t just stop in the middle of the Roll-Out. All of the computers are new and they have a decent hardware.

            1.) We are running a virtual FOG-server on VMWare, the FOG-server has 4 cores and 16 GB RAM, the network-card runs as VMXnet3
            2.) As of now, we only had maybe 1 computer talking to our FOG-server, even with that PC
            3.) Our server has 4 1GbE network-cards as trunk installed
            4.) Our server is connected to a 10 GbE-Switch. That switch is directly connected over a 20 GbE-trunk to our Core-Switch. The classroom ist connected to an access-swtich, which is connected over a 1 GbE-connection to our Core-switch. The infrastructure is pretty new
            5.) We tried to multicast a complete room with 20 computers. After that didn´t work, we made a group with 2 computers, but we couldn´t get it to work either.
            6.) We didn´t try that yet, we will set 2 computers in the same VLAN as out FOG-Server and see, if that works.
            7.) Electrical distance should not be an issue.

            I hope you can work with these answers.

            EDIT: We just tried to have a Multicast-Session in the same subnet as the FOG-Server. The result was the same. Multicast is not working in the same subnet.

              @Dankau said in Deploying via Multicast aborts midway:

              Multicast is not working in the same subnet.

              You are getting the same timeout issue? The switches between the FOG server and test computers had igmp snooping enabled on the VLAN where the FOG server is connected? Ideally for the initial test to have the target computers on the same switch as the FOG server would be a baseline.

              The rest of your network is fine from a bottleneck standpoint.

              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!

                @Dankau What switch manufacture is your networking infrastructure? Cisco Catalyst series?

                I remember a post from not to long ago that something in cisco land needed to be turned on. I also found someone with almost the same initial post as you have but there was no resolution.

                  @george1421 We are using D-Link switches only.

                  After testing the multicast in the same subnet we got the same result, that means we are running into timeouts.
                  I can confirm, after checking multiple times, that IGMP Snooping is enabled on every switch and for the needed VLANs.

                  Sadly, I can´t test multicast on the same switch beacuse every port on our 10 GbE-switch is used.

                    @Dankau So how many hops (network switches) is the target computer away from the FOG server.
