Wi-Fi Array Viewing Status on the Wi-Fi Array131 WDS Statistics The main WDS Statistics window provides statistical data for all WDS client and host links. To access data about a specific WDS client or host link, simply click on the desired link in the left frame to access the appropriate window. You may also choose to view a sum of the statistics for all client links, all host links, or all links (both client and host links). Figure 81. WDS Statistics See Also SSID Management WDS Wi-Fi Array 132Viewing Status on the Wi-Fi Array Filter Statistics The Filter Statistics window provides statistical data for all configured filters. The name, state (enabled — on or off), and type (allow or deny) of each filter is shown. For enabled filters, this window shows the number of packets and bytes that met the filter criteria. Click on a column header to sort the rows based on that column. Click on a filter name to edit the filter settings. Figure 82. Filter Statistics See Also Filters Station Statistics This status-only window provides an overview of statistical data for all stations. Stations are listed by MAC address, and Receive and Transmit statistics are summarized for each. For detailed statistics for a specific station, click the desired MAC address in the Station column and see “Per-Station Statistics” on page 133. Figure 83. Station Statistics Note that you can clear the data for an individual station (see Per-Station Statistics), but you cannot clear the data for all stations using this window. Wi-Fi Array Viewing Status on the Wi-Fi Array133 Yo u c a n Refresh the data (update the window with the latest information) at any time by clicking on the appropriate button. You can also click in the Auto Refresh check box to instruct the Array to refresh this window automatically. See Also Per-Station Statistics Per-Station Statistics This window provides detailed statistics for the selected station. This window is accessed from the Station Statistics window — click the MAC address of the desired entry in the Station column to display its Per-Station Statistics window. Receive and Transmit statistics are listed by Rate — this is the data rate in Mbps. For a summary of statistics for all stations, see “Station Statistics” on page 132. Yo u c a n Refresh the data (update the window with the latest information) or Clear the data (reset all content to zero and begin counting again) at any time by clicking on the appropriate button. You can also click in the Auto Refresh check box to instruct the Array to refresh this window automatically. Figure 84. Individual Station Statistics Page See Also Station Statistics Wi-Fi Array 134Viewing Status on the Wi-Fi Array System Log Window This is a status only window that allows you to review the system log, where system alerts and messages are displayed. Although there are no configuration options available in this window, you do have the usual choice of deciding how the event messages are sorted by clicking in the column header for the desired field (Time Stamp, Priority, or Message). Time Stamp — sorts the list based on the time the event occurred. Priority — sorts the list based on the priority assigned to the message. Message — sorts the list based on the message category The displayed messages may be filtered by using the Filter Priority option, which allows control of the minimum priority level displayed. For example, you may choose (under Services >System Log) to log messages at or above Debug level but use Filter Priority to display only those at Information level and above. Figure 85. System Log (Alert Level Highlighted) Use the Highlight Priority field if you wish to highlight messages at the selected priority level. Click on the Refresh button to refresh the message list, or click on the Clear All button at the upper left to delete all messages. You can also click in the Auto Refresh check box to instruct the Array to refresh this window automatically. Note that there is a shortcut way to view system log messages. If you click Log Messages near the bottom of the left hand frame, WMI displays counts of log messages at different severity levels. Click a count to display just those messages in the System Log window. See Figure 38 on page 79 for more information. Wi-Fi Array Viewing Status on the Wi-Fi Array135 IDS Event Log Window This status only window displays the Intrusion Detection System (IDS) Event log, listing any detected attacks on your network. For descriptions of the types of attacks detected, as well as the settings to fine-tune IDS on the Array, please see “Intrusion Detection” on page 270. The displayed messages may be filtered by using the Filter Event setting, which allows you to select just one type of intrusion to display. For example, you may choose to display only beacon flood attacks. Figure 86. IDS Event Log Use the Highlight Event field if you wish to highlight all events of one particular type in the list. Click on the Refresh button to refresh the message list, or click the Auto Refresh check box to instruct the Array to refresh this window automatically. Although there are no configuration options available in this window, you do have the usual choice of deciding how the event messages are sorted by clicking in the column header for the desired field. Time Stamp — the time that the event occurred. IAP — the affected radio. Channel — the affected channel. Event — the type of attack, as described in Intrusion Detection. SSID — the SSID that was attacked. MAC Address — the MAC address of the attacker. Period — the length of the window used to determine whether the count of this type of event exceeded the threshold. Wi-Fi Array 136Viewing Status on the Wi-Fi Array Current — the count of this type of event for the current period. Average — the average count per period of this type of event. Maximum — the maximum count per period of this type of event.

Gentlemen: The FCC has established certain requirements for U-NII devices as detailed in KDB 443999 and for both DTS and U-NII devices in KDB 594280. The Xirrus host systems are currently only being designed for indoor use, and we understand that when outdoor options are made available we will need to file a C2PC to update grant notes to allow use of the modules in specific outdoor hosts. The current applications are limited to an indoor host system. The requirements applicable to indoor devices in KDB 443999, related to DFS, are: • Devices will not transmit on channels which overlap the 5600 – 5650 MHz band. • Devices must meet all of the other requirements specified in Section 15.407, and it is prohibited to include configuration controls (e.g. country code settings or other options to modify DFS functions) to change the frequency of operations to any frequency other than those specified on the grant of certification for US operation. • All applications for equipment authorization mus…
