I know that this topic has appeared in these forums before because I have already looked through most of the answers for direction. I am still stuck so I am posting this question. Is there any limitation in the 6500 series Sup 1A mod that prevents more then 12-15 multicast clients from joining at any one time.
We have used two products for lab management in the past. Alteris RapidDeploy and Ghost. We are currently moving to ghost as the product of choice. This brings some problems. We just started using multicast. with the alteris we are able to multicast to 60+ machines at a time but with ghost we have problems.
We use a 6506 with a Sup 1A as the core of our network and have a mixture of Cisco 2950's and 3Com 1100's and 3300 in remote buildings. Buildings are connected with 100Meg Fiber. We are behind on our software updates for our 6506 (currently CatOS 5.5(1) and IOS12.1(2)E ED) I have enable multicast on the router, set the interfaces to pim-sparse-dense mode and created a set RP. (suggest in another article) IGMP is enabled on the switch and the switch is aware what ports are multicast enabled.
We are stuck because it seems that no matter what we do, there seems to be a limit that we hit. Given time we can get about 18 machines to join a group but we have never gotten more then that.
Is the problem with our sup module? software level? configuration? I you would like I can post the configs of our 6506 but I have read several CIsco articles and I think I have enable at least the basic multicast commands.
Any help/suggestions would be greatly appreciated

hi
so you say you can get only 18 machines to join the group. What happens when the 18th person leaves the group does another machine join?
Have you pretty much narrowed it down to the equipment and not the Pc's because some NIC drivers in PC does not support multicast very well. Also are you running rgmp on your interface? Can you send me your basic config if possible
thanks

If you reboot machines in the group, other machine that were not part of the group join in. I have rgmp enabled but I didn't do anything to configure any of the individual interfaces. Unlike the multicast router were multicast routing was turn on each interface I know it is not good form but if you change the mode while some machines are in the group and the others are waiting then they will all join. i.e change the mode on the interface from ip pim sparse-dense-mode to ip pim sparse-mode will make them join for that session but not for the next session. When the ghost task starts, any machines that were waiting will then join a group but not the group already in the task. This weekend we are taking both portions to their latest software levels.
Thanks for any insights

I have used Cisco's iptv server along with a 6509. We had over 80 people join a group to watch the super bowl a year ago. There where no problems. Do you have any other routers in your network that have multicast users behind them? Also did you turn CGMP on for both the router and the switch?
03-01-2003 07:51 AM
Other then our internet router the 6506 is the only router on the network. All network segments collapse back to the 6506.
I didn't see a command to turn on CGMP, for either protion, I think that might be on the Sup II level. I have to work with a Sup IA. If there is a command to enable it on the Sup IA then please share because i didn't see anything to set it. If you think that the problem is that we have a Sup Ia please tell me that too because I would love to know.
Thanks for the post.
