Re: Bob the Builder
Now 7 years back but have seen some very strange things on switches from well respected vendors when using multicast for audio.
One had a fault where when a device on a port lets say port 3 subscribes to a stream - it shut off the data on port 3 and sent it out of port 2.
In another installation the owner of the sight would insist that nothing had been changed but multicast all of a sudden stopped working on there network. Turned out the network engineer had saved the configuration of the switch - tested a change and then re-instated the original configuration. Transpired there was a bug in the upload/download of the configuration on the switch that would disable multicast. I hope things have improved by now but considering the vendors reluctance to fix the problem can understand why multicast is not used more.
