@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.
@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.
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.
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.
