  • Page 2: Introducing The Msm317

    Figure 1: A wide variety of devices can be connected to the MSM317. You can configure the network to send traffic through the MSM7xx Controller or, in cases where private access areas are isolated from public spaces, you can bypass the controller completely.
  • Page 3 MSM317 simplifies installation and decreases expensive site surveys required with traditional APs. Its four-port switch and AP are centrally managed through the HP MSM7xx Controller. This means faster configuration of multiple devices, automated software updates, and the delivery of a consistent set of services throughout the network.

  • Page 4: Msm317 Versus Traditional Access Points

    MSM317 versus traditional access points The MSM317 offers several features that distinguish it from a standard access point and make it the right choice for high-density deployments. The table below provides a side-by-side comparison of the MSM317 and the HP E-MSM310 AP.
  • Page 5 Figure 2: Traditional APs transmit at a higher output power than the MSM317 in order to provide coverage to a large area. Multiple users need to share bandwidth. Figure 3: Designed with small spaces in mind, the MSM317 helps to reduce interference with other APs.
  • Page 6 Scaling up is also easier and more affordable as the MSM317 fits into a standard electrical wall box and requires only a single PoE cable drop. Finally, its built-in Ethernet switch delivers voice, video, and data services, while the pass-through port allows for the integration of legacy devices.

  • Page 7: Installation Considerations

    Proper planning and configuration of the MSM317 are critical for providing high-quality wireless service. This section provides an overview of the radio frequency properties of the MSM317, considerations for setting output power and data rates, and guidelines for where to install the unit.

  • Page 8: Location Planning

    Figure 6: The MSM317 provides 120 degrees or greater signal coverage on the horizontal plane and a vertical signal that is narrower than that of a traditional AP. Location planning Care should be taken to install the MSM317 in a location where there are as few obstructions as possible to the signal.
  • Page 9 Figure 7: The faceplate of the MSM317 helps to prevent the antenna from being blocked behind a wall or enclosure and keep the unit from overheating. The trim panel is vented to allow airflow.. The following figures are WLAN coverage maps created using HP RF Planner software for two different room types.
  • Page 10 (B) is excellent. The bathroom (C), which features granite tiles, has useable coverage due to its proximity to the MSM317 (although the tiling impacts coverage in the area adjacent to the bathroom). Coverage in the sitting and kitchen area (D) is inconsistent, ranging between good to nonexistent.
  • Page 11 In this real-world example, the second option was chosen as the one that would provide an excellent balance of coverage and cost, and deliver an acceptable experience to the hotel guest. Figure 9: WLAN coverage map for a suite in a luxury hotel.

  • Page 12: Checking Radio Coverage

    Remember too that the MSM317 already uses reduced power as compared to a typical AP. • Disabling the lower data rates can help to facilitate the client in connecting to the correct MSM317 (that is, the one in the same room) rather than to one in an adjacent room. However, be aware that disabling certain data rates may cause some clients to be unable to associate (although this is uncommon).

  • Page 13: Power Over Ethernet

    IP phone is a Class 2 device, requiring a standard PoE source. Two PoE power settings are available on port 1 of the MSM317: • If the MSM317 is powered from an 802.3af standard PoE source, then port 1 can support Class 1 (3.84 watts) or Class 2 (6.49 watts).

  • Page 14: Uses Of The Pass-Through Port

    Uses of the pass-through port As mentioned, the pass-through port on the MSM317 is intended for use as a PBX pass through. If it is used for any other purpose, it is rated for Category 3 connections. Use of this port in applications requiring Category 5 or greater cabling is likely to impact the performance of that connection.

  • Page 15: Deploying Voice Over Ip

    Deploying Voice over IP The following sections offer guidelines for deploying VoIP telephones with the MSM317. These sections cover IP phones requiring manual VLAN configuration, as well as those that support Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED). VLAN configuration on non-LLDP-MED capable devices...

  • Page 16: Deploying Ip Phones-Lldp-Med Devices

    LLDP-MED capable VoIP phones do not require manual VLAN tagging. Instead, the phones receive their voice VLAN, QoS, and DSCP settings from the MSM317 through a network policy TLV and can immediately begin communication using tagged traffic. For example deployments of LLDP-MED capable IP phones with the MSM317, see the “VoIP/LLPD-MED Use Cases”...

  • Page 17: Authentication

    To configure MAC filtering, use the controller to create lists of MAC addresses permitted to send and receive traffic on an MSM317 switch port. You then specify these lists in the MAC filter area of the port configuration page for the port you want to configure.

  • Page 18: Configuring Per-Room Guest Vlans

    Note: For instructions on configuring port-to-port inheritance, see the HP MSM317 Access Device Installation and Getting Started Guide, the section on configuring the switch ports.

  • Page 19: Voip/Llpd-Med Use Cases

    The following use cases show various ways that LLPD-MED capable IP phones can be deployed with the MSM317. The first scenario (Figure 15) shows a configuration with LLPD-MED phones and no authentication, the second (Figure 16) with LLPD-MED and 802.1X authentication, and the third (Figure 17) with LLPD-MED and MAC authentication.
  • Page 20 Figure 16: In the diagram, the MSM317 provisions LLPD-MED, which automatically supplies VLAN, DSCP, QoS, and 802.1X authentication.
