View Report
OpenStage phones generate QoS reports using a HiPath specific format, QDC (
Q
oS
D
ata
C
ol-
lection). The reports created for the last 6 sessions, i. e. conversations, can be viewed on the
WBM.
To enable the generation of reports, please ensure that:
•
the switch
QoS traps to QCU
(System > SNMP) is activated (see Section 3.3.8, “SNMP”);
•
the conditions for the generation of reports are set adequately (see Section 3.24.9.1, “Con-
ditions and Thresholds for Report Generation”).
For details about QoS reports on HiPath devices, see the HiPath QoS Data Collection V 1.0
Service Manual.
A QoS report contains the following data:
•
Start of report period - seconds
: NTP time in seconds for the start of the report period.
•
Start of report period - fraction of seconds
: Additional split seconds to be added to the
seconds for an exact start time.
•
End of report period - seconds
: NTP time in seconds for the end of the report period.
•
End of report period - fraction of seconds
: Additional split seconds to be added to the
seconds for an exact end time.
•
SNMP specific trap type
: The trap type is a 5 bit value calculated from a list of threshold-
exceeding bits. Every time a threshold is exceeded, the associated bit is set, otherwise it
is cleared.
The trace type bits are defined as follows:
•
Bit 0: Jitter threshold was exceeded.
•
Bit 1: Delay threshold was exceeded.
•
Bit 2: Threshold for lost packets was exceeded.
•
Bit 3: Threshold for consecutive lost packets was exceeded.
•
Bit 4: Threshold for consecutive good packets was exceeded.
•
IP address (local)
: IP address of the local phone.
•
Port number (local)
: RTP receiving port of the local phone.
•
IP address (remote)
: IP address of the remote phone that took part in the session.
•
Port number (remote)
: RTP sending port of the local phone.
•
SSRC (receiving)
: RTP Source Synchronization Identifier of the local phone.
•
SSRC (sending)
: RTP Source Synchronization Identifier of the remote phone.
•
Codec
: Number of the Payload Type applied in the session; see RFC 3551 (Table 4 and
5).
•
Maximum packet size
: Maximum size (in ms) of packets received during the report inter-
val.
