Chapter 4 - MultiFRAD Software
MultiFRAD 100-Series User Guide Introduction This chapter describes the MultiFRAD software from an applications standpoint, showing how to make changes in the configuration with recommendations on the impact of any such changes. The major configuration parameters were set when the software was loaded into your PC and the setup configuration was downloaded to the MultiFRAD at the conclusion of the software installation. The MultiFRAD software is designed for the Microsoft WindowsTM environment.
Chapter 4 - MultiFRAD Software Configuration Port Setup The Configuration Port Setup utility allows you to set up and configure the command port on your MultiFRAD. This dialog is included in the initial installation process. Although parameters can be changed, be sure to note the current status of the software before making any alterations. When you installed the MultiFRAD software, you selected which COM port to use with the configuration port setup.
MultiFRAD 100-Series User Guide MultiFRAD Configuration The MultiFRAD Setup menu consists of eight buttons on which you can point and click, an Events window in the middle of the menu, and a status bar at the bottom of the menu. The eight buttons allow you to display and change the Frame Relay parameters, WAN port setup, Data Ports configuration, and display Statistics. The Events window, in the center of the window, is a smaller version of the print console. It can be a useful tool when troubleshooting.
Chapter 4 - MultiFRAD Software Frame Relay Setup The Frame Relay Setup dialog box displays the CIR Measurement Interval in milliseconds, the Management Type, and details of that management type. The MultiFRAD can detect the DLCI and the Management Type at power-up if you are connected to an active frame relay service. If you change any frame relay parameters, it is important that the new parameters agree with the way your frame relay service is provisioned.
MultiFRAD 100-Series User Guide calculates how much information has been sent on the DLCI, and depending on the congestion management option for a DLCI, the MultiFRAD may stop sending on that DLCI because it has exceeded its CIR or CIR+Be rating. By changing the CIR Measurement interval, the throughput calculations can be made more or less often. Note: performance could be compromised if the MultiFRAD is set to calculate throughput too often.
Chapter 4 - MultiFRAD Software The Congestion Management and throughput Mode settings determine how the MultiFRAD handles congestion. The throughput Mode selects whether the MultiFRAD should use its own throughput calculations to avoid congestion, or simply send data to the network as fast as possible. The MultiFRAD calculates throughput after every CIR Measurement Interval, and can limit throughput to either the CIR (Adhere to CIR) or the CIR plus the Be (Adhere to CIR+Be).
MultiFRAD 100-Series User Guide Data Port Configuration The Data Port Configuration dialog box allows you to change the parameters of the data port to match those of the data device. The MultiFRAD data port can operate in either synchronous or asynchronous mode. If your data device is an asynchronous device, choose the Configure Asynchronous option and configure the MultiFRAD to match your device.
Chapter 4 - MultiFRAD Software Viewing Statistics The Statistics dialog box allows you to view statistics on the major events of the MultiFRAD operation. This dialog box is accessed by clicking the Statistics button on the Main MultiFRAD menu. Statistics can be a helpful troubleshooting tool. For example, viewing the WAN Statistics you can see if the MultiFRAD is sending or receiving on the WAN port.
MultiFRAD 100-Series User Guide WAN Port Statistics The WAN Port Statistics dialog box provides statistical information regarding the MultiFRAD’s WAN port, including the number of packets transmitted/received, and total bytes transmitted/received. The WAN Port Statistics dialog box pertains to the traffic on the MultiFRAD’s WAN port. The Statistics that fall into “Others” category relate to the physical layer between the MultiFRAD and the link device, i.e. the CSU/DSU.
Chapter 4 - MultiFRAD Software Frame Relay Statistics The Frame Relay Management Statistics dialog box can be a useful tool for troubleshooting MultiFRAD installations and monitoring the performance of the link, and determining if the MultiFRAD is talking to the provider’s switch. The Polling Details section lists the various management frames sent and received. For every Status Enquiry Sent, a Status Response should be received from the network.
MultiFRAD 100-Series User Guide The DLCI Statistics dialog box shows the individual DLCI status and statistics. This information can be helpful in determining if the DLCI is active, if it is going up and down, and if the MultiFRAD is experiencing frame relay network congestion (FECN/BECN). It also gives an indication of the momentary throughput on the DLCI.
Chapter 4 - MultiFRAD Software Data Port Statistics The Data Port Statistics dialog box displays statistical information, such as bytes or blocks received/transmitted, for the data port. This window shows the statistics for the data channel. You can view the channel statistics, as well as various hardware signals (CTS, RTS, DSR, DCD, DTR) and XON/XOFF (flow control) status.
