Tot bitr: Bitrate sensed on the eth0 interface
Mon bitr: Bitrate on eth0 corresponding to joined multicasts
CRC errs:
Detected CRC errors. Ethernet CRC errors are most likely caused by a bad cable or a
misconfigured router. A CRC error may impact packet loss measurements such as CC
errors and RTP errors.
Note that the history graphs show the sum for all streams being analyzed across all pages. So for
example, if two streams experience No signal at the same time the No signal graph will increase by 2.
6.4.5 Multicasts — Join
In order for the defined Ethernet multicasts to be monitored by the probe, they must be joined. The
Multicasts — Join
view and the
Multicasts — Streams
view allow the user to select which multicasts
that are joined by the probe.
Streams defined in the
Multicasts — Streams
view will appear as available streams on the left hand
side of the arrows in this view. Select streams to be monitored by clicking them and moving them to
the right hand side of this view using the arrow. Changes should be confirmed by clicking the
Apply
changes button.
The probe can join a maximum of 260 uni/multicasts, these may be freely associated with the 20 probe
pages. The streams will be presented in the Joined multicasts list in the
Multicasts — Parameters
view.
It is possible to flush or fill the multicasts/unicasts to monitor list by clicking the corresponding button.
Note that these operations will take effect immediately; it is not necessary to click
Apply changes
for
multicasts to be joined or unjoined.
