Configuring port ranges for your Edge Servers in Lync Server 2013

 

Topic Last Modified: 2015-07-24

With Edge servers you do not have to configure separate port ranges for audio, video, and application sharing; likewise, the port ranges used for Edge servers do not have to match the port ranges used with your Conferencing, Application, and Mediation servers. Before we proceed with our example, it's important to stress that while this option exists, we do recommend you not change the port ranges, as this may adversely affect some scenarios if you move out of the 50000 port range.

For example, suppose you have configured your Conferencing, Application, and Mediation servers to use these port ranges:

Packet Type	Starting Port	Number of Ports Reserved
Application sharing	40803	8348
Audio	49152	8348
Video	57500	8034
Totals	--	24730

As you can see, your port ranges for audio, video, and application sharing start at port 40803 and encompass a total of 24732 ports. If you prefer, you can configure a given Edge Server to use these overall port values by running a command similar to this one from within the Lync Server Management Shell:

Set-CsEdgeServer -Identity EdgeServer:atl-edge-001.litwareinc.com -MediaCommunicationPortStart 40803 -MediaCommunicationPortCount 24730

Or, use the following command to simultaneously configure all the Edge Servers in your organization:

Get-CsService -EdgeServer | ForEach-Object {Set-CsEdgeServer -Identity $_.Identity -MediaCommunicationPortStart 40803 -MediaCommunicationPortCount 24730}

You can verify the current port settings for your Edge Servers by using this Lync Server Management Shell command:

Get-CsService -EdgeServer | Select-Object Identity, MediaCommunicationPortStart, MediaCommunicationPortCount

Again, while we do provide these options, we strongly recommend you leave things as they are for the port configuration.
