Parameter Description
'Total Egress Bandwidth'
total-egress-bandwidth
[BWProfile_
TotalEgressBandwidth]
Defines the major (total) threshold for video and audio
outgoing bandwidth (in Kbps).
'Total Ingress Bandwidth'
total-ingress-
bandwidth
[BWProfile_
TotalIngressBandwidth]
Defines the major (total) threshold for video and audio
incoming bandwidth (in Kbps).
Thresholds
'Minor Threshold'
minor-threshold
[BWProfile_MinorThreshold]
Defines the Minor threshold value, which is the lower
threshold located between the Yellow and Green states. The
parameter is configured as a percentage of the major (total)
bandwidth threshold (configured by the above bandwidth
parameters). For example, if you configure the parameter to
50 and the 'Egress Audio Bandwidth' parameter to 64,000,
the Minor threshold for outgoing audio bandwidth is 32,000
(i.e., 50% of 64,000).
To consider a threshold crossing:
■ Increase in severity (i.e., Green to Yellow): Only this
value is used.
■ Decrease in severity (Red to Green, or Yellow to
Green):
This value is used with the hysteresis,
configured by the 'Hysteresis' parameter (see below).
Note: The parameter applies to all your configured
bandwidths.
'Hysteresis'
hysteresis
[BWProfile_Hysteresis]
Defines the amount of fluctuation (hysteresis) from the
configured bandwidth threshold in order for the threshold to
be considered as crossed (i.e., avoids false reports of
threshold crossings). The hysteresis is used only to
determine threshold crossings when severity is reduced (i.e.,
from Red to Yellow, Yellow to Green, or Red to Green). The
parameter is configured as a percentage of the Major (total)
bandwidth threshold.
For example, if you configure the parameter to 10 and the
'Egress Audio Bandwidth' parameter to 64,000, the
hysteresis is 6,400 (10% of 64,000) and threshold crossings
are considered at the following bandwidths:
■ Red-to-Yellow (Yellow-Minor alarm severity): 57,600
Kbps [64,000 - (10% x 64,000)]
■ Yellow-to-Green (Green-alarm cleared): 25,600 Kbps
[32,000 - (10% x 64,000)]
'Generate Alarm'
generate-alarms
[BWProfile_GenerateAlarms]
Enables the device to send an SNMP alarm if a bandwidth
threshold is crossed.
