Operation The configuration and management of a NovaRoam network is achieved using the NovaRoam Client Tool application. The Client Tool, based on the Simple Network Management Protocol (SNMP), provides a secure method for viewing or modifying NovaRoam configuration parameters. The Client Tool also provides the ability to initiate firmware updates for NovaRoams. Logging In Upon launching the NovaRoam Client Tool, the login page will be displayed.
IP Routing. The IP Routing page is used to configure the routing settings for the wireless network, including the use of mesh networking or static routes. Security. The Security page is used to configure wireless network encryption and view the MAC Address Revocation list. Admin. The Admin page is used to assign the Radio ID (radio node name), upload security and network configuration files, reboot the radio, and install new radio firmware. Statistics.
• MAC ID. This read-only field displays the unique Media Access Control (MAC) address of the NovaRoam’s wireless interface. The wireless MAC ID is based on the Ethernet interface MAC address but with the second and third sets of digits replaced with “FF” • IP Address. Specifies the IP Address of the Wireless interface of the NovaRoam. The default IP address is 192.168.202.1. This address must be unique for each radio on the wireless network. • Subnet Mask.
• PPP. The Point-to-Point Protocol (PPP) mode is used for emulating an Ethernet connection over a serial interface. • DNP. The Distributed Network Protocol (DNP) mode is used for transferring DNP data between the NovaRoam’s serial port and other Ethernet devices. • Repeater. The Repeater mode is used for NovaRoams that operate as fixed repeaters within the network. • Apply: Saves changes made to the configuration of the Serial Mode Tab.
• Delete. To delete an entry from the DNP table, select the entry in the table and then press the Delete button. • Output Delay. This value defines the amount of time (in milliseconds) between transmitting DNP packets to the NovaRoam’s serial interface after they are received over the wireless interface. This feature has been added to accommodate legacy equipment that cannot receive data packets as quickly as the NovaRoam can deliver them. The default value is 80 milliseconds. • Input Timeout.
The Serial Port Tab is only available when DNP is selected as the serial port mode. The Serial Port Tab is used to configure the communication parameters for the NovaRoam’s serial port. The following parameters can be configured: • Baud Rate. Determines the bit rate used for serial communications. The default value is 9600. • Data Bits. Determines the number of data bits within each character. The default value is 8. • Parity. Determines the setting for the parity bit within each character.
network communication overhead. Larger hello interval values decrease the wireless network’s responsiveness to routing changes but reduce excessive wireless traffic in the process. This value is measured in seconds and has a default value of 30 seconds. • Allowed Hello Loss. The Allowed Hello Loss value determines the number of consecutive hello messages that, when missed, constitutes a link failure. The default value is 2. • Net Diameter.
• Gateway Address. The Gateway Address is the IP address of the router that the NovaRoam will use as its gateway to the corporate LAN, Internet or other routable network. • Wireless Networks. The Wireless Networks table provides a list of wireless networks that are able to utilize the NovaRoam as a gateway to other networks. The table must be populated to include the Ethernet subnets of all NovaRoams that have a need to use a default gateway to reach devices that are not in the wireless network.
• Network. Destination network for the route that is being created. To enter a static route for a device with an address of 192.168.200.1 and a subnet mask of 255.255.255.0, the Network portion of the route entry should be 192.168.200.0. • Subnet Mask. Subnet mask for the destination network for which the route is being created. • Gateway. Next-hop gateway of the destination network for which the route is being created. The gateway will be the IP address of the wireless interface of a NovaRoam.
Security Page The Security Page provides a list of tabs that can be used to view and configure the security configuration of the NovaRoam. Selecting a tab will provide a list of configurable options. Encryption Tab The Encryption Tab is used to enable or disable encryption, change encryption keysets, and upload network and security configuration files. The following parameters can be configured. • Set Network Configuration.
The MAC Filter Tab can be used to view the list of MAC addresses that have been added to the MAC Address Revocation list using the NovaRoam Security Utility. There are no configurable parameters on the MAC Filter Tab. All changes to the MAC Revocation list must be made using the NovaRoam Security Utility and uploaded to the NovaRoam as part of a new security configuration file.
Firmware Tab The Firmware Tab is used to upgrade the firmware that is installed on the NovaRoam. The following parameters can be configured: • File. Use the Browse button to specify the location of the firmware file to be uploaded. • Upgrade. After selecting the firmware file, press the Upgrade button to initiate the firmware upgrade. The NovaRoam will reboot at the conclusion of the upgrade. Note: the radio should not be disturbed during the firmware upgrade process.
• Receive errors. Total number of receive errors. • Received frames dropped. Total number of frames received by the NovaRoam’s Ethernet interface that were discarded. • Unknown protocol received. Total number of frames received by the NovaRoam’s Ethernet interface with unidentified protocol errors. • Bytes sent. Total number of bytes sent by the NovaRoam’s Ethernet interface. • Unicast frames sent. Total number of single destination (unicast) frames sent from the NovaRoam’s Ethernet interface.
• Source quench messages received. Total number of source quench messages received. A source quench message is sent to request a reduction in the packet transmission rate. • Redirect messages received. Total number of redirect messages received. A redirect is sent when an alternate route for the datagram is selected. • Echo request messages received. Total number of echo requests received. An echo request causes the receiving radio to send an echo reply message back to the originating radio.
• Redirect messages sent. Total number of redirect messages sent. A redirect is sent when an alternate route for the datagram is selected. • Echo request messages sent. Total number of echo requests sent. An echo request causes the receiving radio to send an echo reply message back to the originating radio. Echo requests are typically generated by a “Ping” application. • Echo reply messages sent. Total number of echo replies sent. An echo reply is sent to respond to an echo request.
• Default TTL. Time-to-live value used to determine how long a packet that has not reached its destination will remain on the network prior to be discarded. • Total datagrams received. Total number of IP data packets received. • Datagrams with header errors. Total number of received IP data packets that contain errors in the header (i.e., incorrect IP header length). • Datagrams with address errors. Total number of received IP data packets that contain address errors. • Datagrams forwarded.
Wireless Tab The Wireless Tab provides the following statistical information regarding the wireless performance of the NovaRoam. • Bytes received. Total number of bytes successfully received by the NovaRoam’s wireless interface. • Packets received. Total number of packets successfully received by the NovaRoam’s wireless interface. • Received packets dropped. Total number of packets received by the NovaRoam’s wireless interface that failed the validation check for problems such as a corrupted CRC.
• Seconds since charge went off. Duration since AC power has been removed. • Get Battery Status Log. Press the Download button to save the battery status statistics as a text file. AODV Tab The AODV Tab provides statistical information regarding the link quality between all NovaRoams within wireless communication range of the local NovaRoam. The AODV statistics tab is only active when the AODV ad-hoc routing protocol has been enabled on the Ad Hoc Routing tab of the IP Routing configuration page.
