Mediant 500 E-SBC
Parameter Description
Yellow Red Threshold
CLI: yellow-red-threshold
[QOEColorRules_YellowRedT
hreshold]
Defines the parameter threshold values between Yellow (medium
quality) and Red (poor quality) states.
The valid threshold values are as follows:

MOS values are in multiples of 10. For example, to denote a
MOS of 3.2, the value 32 (i.e., 3.2*10) must be entered.

Delay values are in msec.

Packet Loss values are in percentage (%).

Jitter is in msec.

Echo measures the Residual Echo Return Loss (RERL) in dB.
Yellow Red Hysteresis
CLI: yellow-red-hysteresis
[QOEColorRules_YellowRedH
ysteresis]
Defines the fluctuation (change) from the value configured for the
Yellow-Red threshold. When the threshold is exceeded by this
hysteresis value, the device sends a report to the SEM indicating
this change.
Note: If the monitored parameter crosses two thresholds at once
(e.g., from Green to Red), the device ignores the hysteresis value
and reports the call state change to the SEM.
16.3 Configuring Bandwidth Profiles
Bandwidth Profiles enhance the device's monitoring of bandwidth utilization. A Bandwidth
Profile defines bandwidth utilization thresholds for audio and/or video traffic (incoming and
outgoing). Bandwidth Profiles can be assigned to IP Groups (see ''Configuring IP Groups''
on page
263 ), Media Realms (see ''Configuring Media Realms'' on page 251 ), and Remote
Media Subnets (see ''Configuring Remote Media Subnets'' on page 254 ).
Each time a configured bandwidth threshold is crossed, the device can do the following,
depending on configuration:

Determine access control and media enhancements based on bandwidth utilization.
Depending on the crossed threshold type, you can configure the device to accept or
reject calls, or use an alternative IP Profile for the IP Group to which the call belongs.
For more information, see ''Configuring Media Enhancement Profiles'' on page
247 .

Alternative routing based on bandwidth utilization. If a call is rejected because of a
crossed threshold, the device generates a SIP 806 response. You can configure this
SIP response code as a reason for alternative routing (see ''Configuring SIP
Response Codes for Alternative Routing Reasons'' on page
497 ).

Send an SNMP alarm (acMediaRealmBWThresholdAlarm). The device clears the
alarm when bandwidth utilization returns to normal (within the thresholds).
The thresholds of Bandwidth Profiles use the same color-coding as the Quality of
Experience Profile:

Green-Yellow threshold: Lower threshold that indicates that the bandwidth exceeded
a user-defined percentage of the configured threshold. This is referred to as a
"Warning" alarm (i.e., warning you that bandwidth is nearing the threshold). When
bandwidth goes over the threshold, the device considers it as a Yellow state; when it
goes below the threshold, it considers it as a Green state.

Yellow-Red threshold: Indicates that bandwidth has exceeded the configured
threshold. When bandwidth goes over the threshold, the device considers it as a Red
state; when it goes below the threshold, it considers it as a Yellow state.
