Change QoS policies RRS feed

  • Question

  • Hi we are about to enable QoS and I have some questions.

    If I got this right it consists of three parts: Network infrastructure, Windows Server GPOs & Skype policies

    Can one change the skype policies evethough the network and gpo is not configured yet or does this have to be rolled out at the same time?

    for the GPOs, does this apply also to the Edge servers? or is it only front-ends and mediation servers?

    For the Skype policies the configuration below is what we need to adjust, the reset seems to configured to our QoS Plan.

    # Enable QoS

    Set-CsMediationConfiguration -EnableQoS $True -EnableInCallQoS $True

    # Configure servers

    Set-CsConferenceServer -Identity <feserver01> -AppSharingPortStart 40803 -AppSharingPortCount 8348

    # Configure conferencing

    Set-CsConferencingConfiguration -AudioPortRange 40

    This is it?

  • Zid,

    Yes you can change the port settings before you implement the GPO and network for QoS.  Obviously, until you have all parts in place, the QoS settings will not be acted upon - and will be ignored by your switches, routers, etc.

    The GPO's will only work on domain joined servers/clients so you will need to create a local policy on your edge servers.

  • Hi zid,

    For this question, I am agree with paul.hawkins.

    For Lync Server, you can use policy-based QoS to assign the appropriate priority to each media packet. You will need to create a policy for each traffic type for which you want to use QoS. The procedure for each type is the same; however, the procedure for creating a QoS policy for the Edge Server is different.

    Moreover, because normally, for Lync Edge server, it is deployed in the DMZ area, so the GPO will not applying to the Edge server

    Here is a document about how to configure QOS for Edge server, please refer to https://technet.microsoft.com/en-us/library/gg405410(v=ocs.14).aspx
