Proto Local Address Foreign Address State The following entries were pulled from the command output and listed in a table for easy identification. But the additional entries should all be reported as in an Established state and only a single line for each will be in a Listening state. Note that some of these IP:Port combinations may display multiple entries as an active Edge server will have server and client connections. The -n switch skips reverse name lookup on any host IP addresses and will allow the command to complete much faster.)Īmong the results of all static and dynamic ports for any service or application on the server the specific Lync Server listening ports for the various Lync Edge services should be displayed. (The -a switch returns open listening ports as well as any ports with established connections.

To verify that the proper ports are listening and the Edge services are functional the following validation checks can be performed. Example Configurationįor the remainder of this article the following Lync Server Topology is used throughout all example text and screenshots. For example, traffic sent to the internal IP of the Edge server over port 443 would be for relaying media, but traffic sent to the Access Edge external IP over port 443 would actually be external client SIP signaling requests. Thus it is important to always note the IP address of the interface as well as the port. Simply looking at the port number alone is not enough to know what type of traffic might be associated with it as different services will use the same port number for different purposes, albeit on different IP addresses as no two services can occupy the same listening port on the same IP address. The Reverse Proxy server was removed as well as the outbound connections for DNS and HTTP, leaving only the inbound listening ports required on the Edge Server depicted.Īs shown above there are multiple ports utilized by the Edge server with some of the same port numbers (e.g. The following diagram is a slight modification from the Port Summary for Single Consolidated Edge documentation in TechNet. When troubleshooting it is helpful to know the basic Service Name and well as the core application for each of the Edge services. Or use the Services Control Panel applet to view the installed services.On the Edge Server open the Windows Command Prompt and issue the “ net start | findstr Lync” command to list the installed services on the Lync Edge Server.To identify the services and their names perform either of the following actions: Edge Servicesīefore looking at the individual ports it is important to understand that the Edge Server is comprised of five different Windows Services which are responsible for handling different types of traffic and requests. This article takes a look at the services and network traffic which travels to, and through, the Edge Server in an effort to simplify deployment and troubleshooting by gaining a basic understanding of the Edge Server’s purpose. But without knowing some of the basic functionality provided it can be confusing at times to understand what traffic is going where in the topology. If the volume is fine, double-check the menu next to Speakers and see if there's another option to pick from, and then try the sample sound again.The Lync Edge Server is an often misunderstood server role that in theory is not all that complicated.If you don't hear anything when you play the sample sound, make sure your speakers or headphones are turned all the way up (some headphones have physical volume buttons) and that the on-screen settings are at 10.You should hear sound in your headset or speakers. To check the sound in Skype to make sure that it's using the right speakers, select Test audio under the Speakers option.Finally, unplug the microphone and then reattach it. If there aren't other ones to pick from, make sure the microphone is plugged in, powered on (if it has a power switch), and has batteries (if wireless).If the microphone doesn't work with Skype, select the menu next to Microphone and see if there are any other options you might have the wrong device selected.As you talk, you should see the bar light up. With that setting open, notice the volume area under Microphone.
