Use this procedure to enable SfB AX. To do so, you must configure the SDN Manager so that it can push call start and end events
as well as quality updates to the Cisco DNA Center SfB collector.
On the server where the SDN Manager is installed, click the Start menu, and then choose SDNManager Powershell.
From the Powershell prompt, enter the following command:
SDNManager p s
subscriber-id is any case-insensitive identifier you want to use for the Cisco DNA Center SfB Collector.
subscriber-url is http://cisco-dna-center-hostname-or-IP-address:30732/api/services/skype/event.
SDNManager p s CiscoDNACenter submituri=http://cisco-dna-center.example.com:30732/api/services/skype/event
In some cases, running the SDNManager command in the SDNManager Powershell might not work because the SDN Interface installation process did not add the folder
containing SDNManager.exe to the user or system path. In this case, you can either specify the full path to SDNManager.exe
("C:\Program Files\Microsoft Skype for Business Server\Microsoft Skype for Business SDN Manager\SDNManager.exe" by default),
or add the containing folder to the user or system path.
To review the default call server configuration, enter the following command: Get-CsMediaConfiguration.
The InCallQoSIntervalSeconds configuration parameter controls both the initial wait period before the SDN Manager sends its first call quality update,
as well as the minimum interval between subsequent updates. For example, with the default value of 35 seconds, the first quality
update is always sent 35 seconds after the start of a call. After that, if SfB determines that the quality of that call has
changed significantly to warrant sending out additional quality updates, those updates will be sent no more than once every
Before changing the default value, take into consideration that while lowering this value reduces the time before the first
quality update is sent and reflected in Cisco DNA Center, it also reduces the minimum interval between quality updates. Because these updates are typically generated due to degraded
network conditions, this can have the effect of exacerbating network issues with additional quality update traffic.
To change the default wait period, enter the following command: Set-CsMediaConfiguration -InCallQoSIntervalSeconds
After you have completed the preceding steps, SDN Manager starts pushing call start and end events as well as quality updates
to the Cisco DNA Center SfB collector.
