Multicast video dropping every 3 min

‎05-12-2016 06:00 AM - edited ‎03-08-2019 05:44 AM

I am having an issue that I need some assistance with.. I have video dropping and can't figure out why. Let me see if I can draw you a picture of my setup.

I have a 3850 switch stack that consist of a 24port POE switch and a 12 port SFP switch. The switch stack has 8 vlans on it... All vlan interfaces are configured here also. The 24port switch ports are configure for one vlan (we will say number 8). Vlan 7 is for management only. I have 6 separate dumb switches that connect via fiber to this stack that each are on a separate vlans ( 1 - 6 [These are not actual vlan numbers I am using]). I have multicast video that streams from each of the 6 vlans.

Now here is my issue... I can view vlans 1-5 on a system connected to vlan 6. No issues. I can view 1-4,6 on a system connected to vlan 5. No issues. I can view 1-2,4-6 on a system connected to vlan 3. No issues. I can view 1,3-6 on a system connected to vlan 2. No issues. I can view 2-6 on a system connected to vlan 1. No issues. Notice I didn't include vlan 4. Now, I can view 1-3,5-6 on a system connected to vlan 4. After about 3 minutes, video from vlan 3 drops out. I can reconnect to video then after another 3 minutes it drops again. No other systems on the other vlans are dropping the multicast stream from vlan 3.

My configuration consist of:

ip multicast-routing

Each vlan interface has ip pim sparse-dense-mode and ip igmp version 3 (just a last minute add to see if it would help).

Am I missing something causing this to drop? I have searched through bugs and found some multicast issues but not something like I am experiencing..

Another note is that I have ran debug ip igmp ***.***.***.*** and debug ip mrouting ***.***.***.*** (multicast address). I can see at the time the video drops, the switch says that the system viewing the multicast was deleted from the group. (Sorry I don't have exact info but can reproduce this if needed). This happens every time the video drops..

Any help or thoughts is greatly appreciated...

3 mins or 210 seconds? i guess its 210 seconds..

can you check if the (S,g) is disappearing or the timer keeps on going down from 210 and eventually gets deleted?

Well found this issue.. Had nothing to do with my Cisco configuration. The computer where I was viewing the multicast stream from was blocking the IGMP query so since it didn't answer to the query, it was removed from the multicast group. We implemented a firewall rule on the computer and everything is happy happy happy.
