Channel Select the desired channel to monitor.
FIGURE 3-11: ASSOCIATION REQUEST AND RESPONSE ZENA™ Wireless Network Analyzer User’s Guide DS51606C-page 30 © 2008 Microchip Technology Inc.
ZigBee™ Protocol Tools The various portions of the message are color coded for clarity. TABLE 3-15: PACKET SNIFFER COLOR CODING Field MAC Header Color White MAC Commands and Beacons Red NWK Header Lime NWK Commands Fuchsia APS Header Yellow APS Payload/Decoding Aqua Security Header and Encrypted Data Blue Unknown Olive Figure 3-12 shows a message being routed from the originator to the final destination and an APS level Acknowledge being routed back.
FIGURE 3-12: APPLICATION MESSAGE WITH APS LEVEL ACKNOWLEDGE ZENA™ Wireless Network Analyzer User’s Guide DS51606C-page 32 © 2008 Microchip Technology Inc.
ZigBee™ Protocol Tools Each message can contain a great deal of information, making it difficult to view on the screen. The Packet Sniffer window can be scrolled, but the ZENA analyzer also offers three different levels of viewing the MAC, NWK and APS level information. Each layer can be configured separately on the Network Monitor window by adjusting the “Verboseness Level”. There are three levels offered (see Table 3-16).
FIGURE 3-13: APPLICATION MESSAGE WITH NUMERIC DISPLAY ZENA™ Wireless Network Analyzer User’s Guide DS51606C-page 34 © 2008 Microchip Technology Inc.
FIGURE 3-14: APPLICATION MESSAGE WITH CONDENSED DISPLAY ZigBee™ Protocol Tools © 2008 Microchip Technology Inc.
ZENA™ Wireless Network Analyzer User’s Guide The data can be viewed and analyzed to some degree while real-time monitoring is in progress. For more advanced analysis, real-time monitoring must be halted by clicking the Stop button or selecting the Operation>Stop Sniffing/Playback menu option. To save the data for analysis at a later time, click the Save button or select the File>Save menu option. 3.3.1.
ZigBee™ Protocol Tools 3.3.2.2 USING THE PACKET FILTER Click the Filter button or select the Tools>Filter menu option to enlarge the Network Monitor window and display the filter options. FIGURE 3-15: NETWORK MONITOR WINDOW WITH FILTER The filter is useful for displaying only selected packets in the Packet Sniffer window. For example, suppose we want to see all beacons generated by our network. Set up the filter as follows: 1. 2. 3. 4. 5. 6. Clear all “MAC Commands” checkboxes except “MAC Beacon”.
DS51606C-page 38 If the “Source Address” and “Destination Address” areas are empty and are needed for your desired filter, replay the network formation portion of the data. If you will be working with a network that maintains the same structure, you may want to save a captured data file that contains the network formation for populating these fields. FILTERED BEACONS To close the filter and return the Network Monitor window to its original size, click the Filter toolbar button.
ZigBee™ Protocol Tools 3.3.2.3 HIDING AND UNHIDING PACKETS Packets in the Packet Sniffer window can be hidden in two ways: • Using the filter function as described in Section 3.3.2.2 “Using the Packet Filter” • Right clicking on a packet and selecting Hide from the pop-up menu Note: Multiple packets can be selected for hiding by holding down the control key while clicking each desired packet.

ZigBee™ Protocol Tools 3.4 ADVANCED NETWORK MONITORING AND ANALYSIS 3.4.1 Network Configuration Display Window The ZENA Wireless Network Analyzer provides an extra level of network monitoring and analysis with the Network Configuration Display (NCD). Open the ZENA™ Network Configuration Display window by clicking the Network Configuration Display button or by selecting the View>Network Configuration Display menu option on the Network Monitor window.
ZENA™ Wireless Network Analyzer User’s Guide When the ZENA analyzer receives a message from a device, it creates a node in the NCD window. The label for the node will be its 64-bit MAC address. To see the node’s PAN ID and 16-bit network address, hold the cursor over the node. If the node’s MAC address is not available, the label for the node will be the node’s PAN ID and 16-bit network address. If the ZENA analyzer monitors network creation, it can also color code the nodes according to device type.
ZigBee™ Protocol Tools 3.4.2 Viewing Network Formation The following sequence of figures shows how network formation appears on the NCD window. First, the ZigBee protocol coordinator sends a beacon request. FIGURE 3-20: NCD BEACON REQUEST Since there are no nodes on this channel, no beacons are received, and the ZigBee protocol coordinator forms a network. Next, a ZigBee protocol router tries to find a network to join.
ZENA™ Wireless Network Analyzer User’s Guide FIGURE 3-21: NCD BEACON Note that the ZENA analyzer can tell from the beacon that this device is a ZigBee protocol coordinator, but it does not yet know its MAC address. The ZigBee protocol router will now try to join the network by sending an Association Request. The ZENA analyzer can tell from the Association Request what type of device is trying to join the network. FIGURE 3-22: DS51606C-page 44 NCD ASSOCIATION REQUEST © 2008 Microchip Technology Inc.
ZigBee™ Protocol Tools After a short time, the ZigBee protocol router will send a Data Request, asking for the Association Response. The ZigBee protocol coordinator will respond by sending the Association Response. FIGURE 3-23: NCD ASSOCIATION RESPONSE Now the device has joined the network. This relationship can be seen by clicking Clear All Message Lines to display only the network association lines. FIGURE 3-24: © 2008 Microchip Technology Inc.
ZENA™ Wireless Network Analyzer User’s Guide Figure 3-25 shows the NCD window after the creation of a four-device network. FIGURE 3-25: Note: DS51606C-page 46 FOUR-DEVICE NETWORK If you will be working with a network that maintains the same structure, you may want to save a captured data file that contains the network formation. You can play back this file to establish the devices on the network, and then play back the various data files containing the network traffic you would like to monitor.
ZigBee™ Protocol Tools 3.4.3 Viewing Network Traffic After the network above was created, one of the devices attempted to send a message to another device. The path that the message followed is shown in Figure 3-26. FIGURE 3-26: NCD MESSAGE PATH The NCD window shows how the message went from device 00.04.A3.00.00.00.00.88 to device 00.04.A3.00.00.00.00.01, traveling through two other nodes. This particular message requested an APS Acknowledge. Figure 3-27 shows the path of the APS Acknowledge.
ZENA™ Wireless Network Analyzer User’s Guide 3.4.4 Customizing the Network Configuration Display Window When analyzing network traffic, it is often helpful to understand the physical relationship between the devices. The ZENA analyzer allows you to select a bitmap as the background of the NCD window. The nodes can then be dragged so that they match their physical location. For example, Microsoft® Visio® drawing and diagramming software can be used to generate a simple floor plan.
ZigBee™ Protocol Tools FIGURE 3-29: NCD WINDOW WITH FLOOR PLAN BACKGROUND When network formation is played back and displayed on the NCD window, the nodes can be moved to the location on the bitmap that represents their physical location. © 2008 Microchip Technology Inc.

ZigBee™ Protocol Tools 3.4.5 Analyzing Network Traffic The ZENA Wireless Network Analyzer can provide a great deal of information about device and network operation. The Packet Sniffer window can be used to ensure that messages are appearing on the air as expected, and that the messages have the correct format. The NCD window can be used to ensure the network is formed in the correct manner. The ZENA analyzer can show how messages propagate through the network.
