    MobileLAN access 21XX System Manual After the root access point is elected, it transmits hello messages on all enabled ports. The spanning tree forms as other access points receive hello messages and attach to the network on the optimal path to the root. A non-root access point also transmits hello messages after it is attached to the network.
  • Page 95 Configuring the Spanning Tree Bridging Layer Functions Table Function Explanation Network Access points automatically configure into a self-organized network using a spanning tree Organization topology. As devices are added to or removed from the network, the access points automatically reconfigure to maintain reliable operation. The spanning tree provides efficient, loop-free forwarding of frames through the network and allows rapid roaming of end devices.

    MobileLAN access 21XX System Manual About IP Tunnels The physical boundary of a wireless network is usually defined by the presence of an IP router. Multiple independent wireless networks may exist, each with its own LAN ID, root access point, and set of wireless end devices. In this environment, an end device can only operate within the limited coverage area of its own network and cannot roam across IP subnet boundaries.

    The Intermec NNL protocol is a simple Non-routable Network Layer protocol that is used to carry high-layer data in a local area network environment. An Intermec NNL gateway forwards NNL traffic to non-NNL hosts such as TCP/IP hosts. You can use the default flooding and bridging settings, and minimize triangular routing, if NNL gateways are located on the home subnet.

    2106. Note: Certain functions available through the AP monitor can erase the access point configuration. Intermec strongly recommends that you only use the AP monitor when absolutely necessary. For example, you might use the AP monitor to upgrade the access point software or when instructed to do so by Intermec Technical Support.

  • Page 212: Using Ap Monitor Commands

    MobileLAN access 21XX System Manual Using AP Monitor Commands You can display a list of AP monitor commands on the screen anytime you see the ap prompt. To list AP monitor commands • Press any key (except the letter B, which reboots the access point), and then press Enter.

  • Page 213: Using Content Addressable Memory (Cam) Mode Commands

    CAM, which is controlled by the Field Programmable Gate Array (FPGA), filters packets based on the radio’s capability. Because the commands can cause undesirable results if not properly executed, you should contact Intermec Technical Support for assistance if you are unsure about the proper procedure to use.

  • Page 214: Using Test Mode Commands

    Within the AP monitor, Test mode lets you perform certain test functions. Because the commands can cause undesirable results if not properly executed, you should contact Intermec Technical Support for assistance if you are unsure about the proper procedure to use.
