> ## Monitoring

> This chapter describes using the Web interface to obtain detailed information about the settings and performance of the unit.

> Click the Monitor button to access this information.

> The following tabs appear in the Monitor section:

> - Wireless (see Monitor the Wireless Settings)
> - ICMP (see View Number of ICMP Messages)
> - Per Station (see View Per Station Statistics)
> - Features (see View Features Supported)
> - Link Test (see Test Link Quality)
> - Interfaces (see Monitor Interfaces)
> - IP ARP Table (see View the Mapping of IP and MAC Addresses)
> - IP Routes (see View Active IP Routes)
> - Learn Table (see View All Detected MAC Addresses (Learn Table))
> - RIP (see View RIP Data)
> - Radius (see View RADIUS Traffic Information)
> - QoS (see View Quality of Service (QoS) Information)
> - Temperature (see View Temperature Log)
> NOTE: The Radius tab is available on BSUs only. The RIP tab is relevant only in Routing mode.

> Help and Exit buttons also appear on each page of the Web interface; click the Help button to access online help; click the Exit button to exit the application.

> For an introduction to the basics of management, see Basic Management.

> ## Monitor the Wireless Settings

> ## General Performance

> Click Monitor > Wireless > General to monitor the general performance of the wireless interface.

> ## WORP Interface Performance

> Click Monitor > Wireless > WORP tab to monitor the performance of the WORP Base or WORP SU interfaces.

> The Registration Last Reason field indicates either a successful registration (a value of 1) or it indicates the reason why the last registration failed. Possible values for the Registration Last Reason field are as follows:

> - 1 = None (successful registration)
> - 2 = Maximum number of SUs reached
> - 3 = Authentication failure
> - 4 = Roaming
> - 5 = No response from SU within the Registration Timeout Period
> - 6 = Low Signal Quality

> ## View Number of ICMP Messages

> Click Monitor > ICMP to view the number of ICMP messages sent and received by the unit. It includes ping, route, and host unreachable messages.

> ## View Per Station Statistics

> Click Monitor > Per Station to view Station Statistics. On the SU, the "Per Station" page shows statistics of the BSU to which the SU is registered. On the BSU, it shows statistics of all the SU's connected to the BSU.

> The page's statistics refresh every 4 seconds.

> ## View Features Supported

> Click Monitor > Features to view the following information.

> NOTE: A BSU shows how many WORP SUs it can support; the SU shows how many Ethernet hosts it supports on its Ethernet port as the "Max Users on Satellite" parameter.

> ## Test Link Quality

> Click Monitor > Link Test to find out which wireless stations are in range and to check their link quality.

> NOTE: Link Test requires Internet Explorer version 6.0 or later. Earlier versions do not support Link Test.

> Link Test for the unit reports the Signal-to-Noise Ratio (SNR) value in dB; the higher this number, the better the signal quality. Furthermore, it reports the signal level and noise level in dBm. The latter two are approximations of the level at which the unit receives the signal of the peer unit and the background noise.

> - Clicking Explore from a BSU displays all its registered SUs.
> - Clicking Explore from an SU displays only the BSU with which it is registered.

> All stations displayed after "Explore" come up "Disabled." Select a station by changing Disabled to Start and click the Link Test button. You can change multiple stations to Start, but only the last station in the list is displayed as the remote partner when you click the Link Test button.

> The Link Test provides SNR, Signal, and Noise information for both, the local and the remote unit's levels. Link Test stops when you close the Link Test page.

> ## Monitor Interfaces

> Click Monitor > Interfaces to view detailed information about the IP-layer performance of the unit's interfaces. There are two sub-tabs: Wireless and Ethernet. The following figures show both interfaces.

> ## View the Mapping of IP and MAC Addresses

> Click Monitor > IP ARP Table to view the mapping of the IP and MAC addresses of all radios registered at the BSU. This information is based upon the Address Resolution Protocol (ARP).

> ## View Active IP Routes

> Click Monitor > IP Routes to view all active IP routes of the unit. These can be either static or dynamic (obtained through RIP). This tab is available only in Routing mode, and you can add routes only when in Routing mode.

> ## View All Detected MAC Addresses (Learn Table)

> Click Monitor > Learn Table to view all MAC addresses the unit has detected on an interface. The Learn Table displays information relating to network bridging. It reports the MAC address for each node that the device has learned is on the network and the interface on which the node was detected. There can be up to 10,000 entries in the Learn Table. This tab is only available in Bridge mode.

> ## View RIP Data

> Click Monitor > RIP to view Routing Internet Protocol data for the Ethernet and Wireless interfaces.

> ## View RADIUS Traffic Information

> Click Monitor > Radius to view information about the traffic exchanged with a RADIUS server.

> ## View Quality of Service (QoS) Information

> Click the Monitor button and the QoS tab to view summary information about the Quality of Service per BSU and for each SU registered with that BSU.

> This tab is available only on the BSU.

> ## View Temperature Log

> The feature for reporting and logging internal unit temperature observes and reports the internal temperature of the unit. Temperature is logged and an SNMP trap sent when the internal temperature crosses the limit of 0ºC to 55ºC (at 5 degrees before the limit, the unit issues a warning trap).

> You can select a recording interval from one to sixty minutes, in 5-minute increments on the Configure: System tab. A log file holds the recorded data. The log can hold at least 576 entries (two days with the refresh time of 5 minutes). For further analysis, the log can be exported to a text file with a new line feed as a line separator.

> The Temperature Log contains two sub-tabs:

> - The Current Temperature tab indicates the unit's current temperature. The current temperature value is refreshed every 4 seconds.

> - The Log tab keeps track of the temperature recorded at the end of each configured logging interval. You can reset or refresh the log using the Reset and Refresh buttons.
