# ModifyTrafficMirrorFilterNetworkServices


Allows or restricts mirroring network services.

 By default, Amazon DNS network services are not eligible for Traffic Mirror. Use `AddNetworkServices` to add network services to a Traffic Mirror filter. When a network service is added to the Traffic Mirror filter, all traffic related to that network service will be mirrored. When you no longer want to mirror network services, use `RemoveNetworkServices` to remove the network services from the Traffic Mirror filter.
