  • Page 14: Chapter 2 Audio-Video Profile Templates And Network Profiles

    Audio-Video Profile Templates and Network Profiles The switch provides preconfigured audio-video (AV) profile templates that you can configure and assign to switch ports and VLANs, thereby creating network profiles. You can also set up your own AV profile templates. These are the essential differences between an AV profile template and a network profile: •...

  • Page 15: Overview Of Preconfigured Av Profile Templates

    Overview of preconfigured AV profile templates An AV profile template integrates NETGEAR proprietary settings, allowing you to optimize specific audio and video environments. You can use an AV profile template to create one or multiple network profiles. For example, you could use the same AV profile template to set up three network profiles based on a location within a building: one network profile for the lobby, one for the theater, and one for the patio.

  • Page 16: About Audio Video Bridging

    802.1AS timing and synchronization is an audio video bridging (AVB) feature. AVB (also referred to as 802.1AS) requires a license. For information about purchasing a license, contact NETGEAR or your local NETGEAR reseller. The IEEE 802.1AS standard specifies the protocol and procedures used to ensure that the QoS requirements are guaranteed for time-sensitive applications, such as audio and video.

  • Page 17: About Ptp Residency Time Stamping

    AV Line of Fully Managed Switches M4250 Series Note: Another PTP feature that the switch supports, PTP residency time stamping, is incompatible with 802.1AS on the same switch. For more information, see About PTP residency time stamping on page 17. If you must support both AVB and PTP residency time stamping in your network, we recommend that you use two separate switches.

  • Page 18: Network Profiles

    AV Line of Fully Managed Switches M4250 Series that can use PTP residency time stamping (such as Audio Dante), PTP residency time stamping is automatically and globally reenabled. • PTP residency time stamping is not a strict requirement: Whether you need to use PTP residency time stamping depends on your network setup rather than the network profile that you use.

    Multicast Communication from point to multipoint is called multicasting. The source host (point) transmits a message to a group of zero or more hosts (multipoint) that are identified by a single IPv4 destination address. Although the task can be accomplished by sending unicast (point-to-point) messages to each of the destination hosts, multicasting is the preferred method for this type of transmission.
