Any DLNA / networking experts?
I have a problem at work, and I have to be very vague on the customer and their network for obvious reason, it involves DLNA traffic over a switched network (DLNA being the media streaming protocol).
What I will do is draw up a bit of a map etc and post it shortly, In the meantime, if you any good with networks let yourself be known by replying to this thread |

Layer 2 connectivity diagram
http://farm6.static.flickr.com/5134/...b0595ba0_b.jpg Basically the media wont stream from the server to the TV when configures to the diagram specs, however if the customer patches the server into the 3750 it works fine. I know that DLNA works on broadcast and multicast, however I know little regarding multicasting so this may be where the issue lies although I cant see any issues myself Initial Diagnostics by myself; Checked end to end connectivity to rule out any trunking issues Confirmed that no layer 2 access lists exist (I suppose the above step also did this) Confirmed that no suppression of broadcast traffic is present on the related switch ports (trunks included) What I was planning to do next, was configure a mirror port to map what traffic is reaching the TV using wireshark (packet sniffer) This is basically done as a favour for the customer as this issue doesn't fall under the current level of support, so work have tasked me (i volunteered) to take a look into the issue but due to it being a favour I have very little work time to spend on it but this does mean it doesn't really matter if it gets resolved as the customer is not paying for it Also worth noting that a virtual switch exists on the ESXi server |
