We have configured Multicast routing on 3550-EMI Core Switches as well as CGMP compatibility for our 3548XL L2 edge switches. Currently Multicast imaging works in most of the clients LAN locations. However at one particular site they are having massive packet loss reported by the client at which point the image process fails on all but one or two computers.
I am pretty confident that the network configuration is not the issue. The site we are having problems at was the demo site for the design and rollout of the rest of the networks edge sites so the configs are virtually identical. We have done everything from nuke the network configs and reconfigure from scratch to doing a diff against a working site and the broken sites configs and so far nothing jumps out at me. Today we are testing again and I have noticed that the Multicast stream from the imaging server is 15214 kbps via the sh ip mroute active command. From what I understand this tells me that my imaging server is dishing out a 15214 kbps multicast stream for the clients to connect to. This in turn translates to a 15+ mbps data stream. The system admin doing the imaging thinks he is sending a 1 mbps data stream and is arguing that the 15+ number is a byproduct of 15 client systems connecting to the image
I will attach a sanatised config of the 3550 EMI as well as one of the 3548XL edge switches. Any thought or ideas you might have would be greatly appreciated.
