Diagnosing problems with your multicast setup | Contributed code and patches

Please see the Beacon web page at
http://dast.nlanr.net/projects/beacon/#issues for more information -- There is a known bug with RTT right now which we are working on.

Local RTT is the RTT report from this Beacon locally, without relaying reports back to the Central Server. This is only what this one particular Beacon (teevee.aarnet.edu.au, in this case) sees by itself.

The "RRs" column is the count of RTP Receiver Reports received from each SR during the previous interval. For any given interval, the count of reports should be approximately the same. If your Beacon's report count is much lower than the others, it means your Beacon has only recently joined the multicast If you know you Beacon has been running for some time, it may be showing router-level multicast problems, which is why the option was included in this release of the Beacon. If your Beacon is joining and leaving and joining and leaving, this it what that would look like.
