6.7.2 Traffic — Detect
The Traffic Detect view displays all UDP traffic sensed by the probe. Note that promiscuous network
mode should be enabled in the Setup — Params view for the probe to detect all traffic, and not only
multicasts already joined by the probe. Note that generally the upstream switch or router will not output
streams that are not joined by downstream equipment, i.e. usually only joined streams will be available
for monitoring.
If the unicast/multicast destination address is known to the probe (i.e. listed in the Multicasts — Streams
view) the stream’s Name is looked up, otherwise a generic name is used.
When the Traffic — Detect view is entered after probe booting, the probe will continuously try to detect
streams. Click the View list offline button to view the stream list in offline mode. Click the Refresh
button to update the stream list in offline mode.
The source address makes it possible for the probe to distinguish between multicasts with the same
destination IP address and port, provided that Source specific multicasts has been enabled in the
Setup — Params view.
If the stream is currently joined by the probe (i.e. the probe is currently monitoring the stream), the
Joined field is set to yes.
Detected streams can be added to the probe’s stream list by selecting streams and clicking the Add
selected to stream list . To add all detected streams the Add all to stream list button can be pressed.
Only streams not already in the probe’s stream list are considered. Clicking the
Export
button will
generate an XML-file that opens in a new window.
A drop down menu allows filtering of detected streams, making is possible to view streams of a specific
type only. Stream types are defined in the Traffic — Filter setup view. If the AEO option is enabled for
the probe the Detect list will contain the following additional columns: Mapping, signal, RTP drops, CC
errors and Bitrate. These parameters are the same as on the
Multicasts page.
