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 261), 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 538).

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.

Description
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.
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.
