CHAPTER USING PARAMETER EDITOR General DLL Files The Parameter Editor is a shared run-time Dynamic Link Library (DLL) file which is called from both VLoad and VMS software applications. It is used as an extension to both of these programs in providing an extendable User Interface. This file resides in a locally sourced directory for access by the host application. To access the Parameter Editor from either the VMS or VLoad, the appropriate DLL files are required.
General Updating DLL Files To update the Parameter Editor for one or both of the installed applications, VLoad and/or VMS, the new DLL file is simply copied into the appropriate directory for that application. VMS Update On both the VMS Client machine and the VMS Server, copy the distributed DLL file to the following directory: C:\Program Files\Vipersat\VMS\3.0\bin Vload Update Copy the distributed DLL file into the same local directory that holds the VLoad application (.exe).
Parameter Editor Tree Menu Parameter Editor Tree Menu The Parameter Editor displays the editable parameter categories for each network modem/router in the form of a tree menu. The tree appearance will vary depending on the selected Working Mode, and whether the unit has both a modulator and a demodulator, or a demodulator only. Vipersat Hub Vipersat Remote Expansion w/o Mod Figure 2-1 Tree Menus, Vipersat Modes From the VMS, Parameter Editor is accessed by selecting the modem Configure command.
P a r a m et e r E d i t o r T r e e M e n u alert icon will be displayed next to the field in question. Clicking on the icon will display a pop-up info-tip that explains the conflict. Figure 2-2 Alert, Parameter Conflict Edit the setting to eliminate the conflict. Note that, once the setting is corrected, the alert icons will remain visible until either the dialog is exited (i.e., another menu item is chosen) or the Editor window is closed.
W or k i ng M o d e Working Mode Clicking on the Working Mode menu item displays the dialog shown in figure 2-3. When the Parameter Editor opens, this is the window that first appears. This parameter is used to configure the modem/router with the function (role) it is to perform in the network. The first four modes listed are for Vipersat roles, the last four modes are for non-Vipersat roles.
Working Mode available as a resource for dedicated communications with the other end of the satellite link. Table 2-1 lists some typical network functions and the corresponding network role a sample SLM-5650A must have to perform its functions.
Vipersat Vipersat Clicking on the Vipersat menu item displays the dialog shown in figure 2-4. Figure 2-4 Vipersat dialog Unit Name Enter any name (24 characters or less) for the node which serves to identify the Vipersat unit on the network. Network ID The number entered in the Network ID field defines the network of which the target Vipersat unit is a member. All devices in a common network will share the same network ID.
Vipersat STDMA Clicking on the STDMA menu item displays the STDMA dialog, the appearance of which will vary based on whether the unit function is set to Hub or Remote (as selected from Working Mode), and the chosen allocation method.
Vipersat For example, the SLM-5650A shown in figure 2-5 is operating as a Hub, with the allocation method set for Entry Channel Mode. Some of the parameter fields may be unavailable for input (grayed out), depending upon the method that is selected. The screen shown in figure 2-6 shows an SLM-5650A being used as a Remote, with only a subset of the fields that appear for a Hub unit.
Vipersat • Entry Channel - Entry Channel Mode provides an immediate acquisition into an SCPC channel upon Remote burst registration. NOTE Note: If the Hub STDMA mode is GIR (Guaranteed Information Rate) or Entry Channel, normal load switching is automatically disabled. In GIR mode, the Remote is switched to SCPC as soon as the GIR threshold is reached, if there is a switch rate defined.
Vipersat GIR (Guaranteed Information Rate) In the GIR mode, the initial computed slot size value is the same as the Dynamic Cycle mode except there is no maximum limit. After all Remotes have been assigned slots, the burst map is checked to see if the total cycle length exceeds 1 second. If not, then all requirements are satisfied and the burst map is complete.
Vipersat Cycles per Map This menu item, which appears for all Hub types except Dynamic Cycle and GIR, displays the number of spin cycles that will occur between each broadcast of the Burst Map by the Burst Controller to the Remotes. One cycle is the amount of time it takes for all Remotes in a group to burst on the common channel. The burst map provides each Remote with its allocated bandwidth and position in the cycle.
Vipersat NOTE Note: The STDMA group number and the network ID are independent. There can be multiple STDMA groups within a single network. Stats Collection This field appears for Hub modem only. The Burst Controller monitors statistics in the received ACK from each Remote. The statistics report the fill status of the STDMA buffers. The Burst Controller builds a table of the group and calculates the relative buffer fill for each Remote.
Vipersat signal lock to occur before data is sent, thus preventing data loss. Higher data rates allow for a shorter preamble, since it is easier to achieve signal lock. The setting for this parameter (default = 0) should be obtained using the Vipersat STDMA Calculator—a free tool available from Vipersat Customer Support. Burst Map Multicast IP Address This field appears for Hub and Remote modems.
Vipersat Figure 2-8 STDMA Remote List dialog Figure 2-9 Add STDMA Remote dialog, ECM For a GIR Hub, enter the automatic load Switch Rate and the Guaranteed Information Rate for the Remote. Set the Switch Rate to a value greater than the GIR to allow the Remote to be automatically switched out of STDMA and into SCPC mode when traffic exceeds the GIR. A Switch Rate of 0 will prevent the Remote from being switched out of STDMA and into SCPC mode. Switch type 0 corresponds to Load Switching.
Vipersat After field entry, add this Remote to the list by clicking the Add button. Note that the Add Remote dialog remains open after adding a Remote so that additional Remotes can be added easily. Click the Close button to return to the List dialog. When one or more Remotes that appear in the list are selected, the Remove and Modify buttons become active. The Clear button is used to clear all Remotes from the list.
Vipersat Enabling the Retry feature allows specifying the number of Cycles to have pass prior to returning the Remote to the Burstmap for purposes of re-establishing communications. When a Remote is removed from the STDMA group, entering a value in the Retry Cycles field defines the amount of time that is allowed to pass before a retry attempt is made to return the removed Remote to the group.
Vipersat Figure 2-11 Automatic Switching: Hub dialog Figure 2-12 Automatic Switching: Remote dialog Slot Capacity This field appears for Hub modems only. The Slot Capacity field allows setting the threshold or level of slot-capacity at which the transmission switches from STDMA mode to SCPC mode.
Vipersat Typically the default setting will be sufficient, but there may be unique network configurations which require modifying the STDMA slot capacity value. Tip: The VMS provides the means for setting the high and low switch rate limits for each Remote. Refer to the VMS User Guide for details. Switch Delay This field appears for Hub modems only.
Vipersat Typically the default value will be sufficient. Note that this value must be less than the value specified for the SCPC Step Up Threshold. Step Delay This field appears for the Remote modem only. The Step Delay feature provides a switching delay period to ensure that a premature switch up or down in the SCPC rate does not occur due to a temporary rise or fall in traffic. Excess Capacity This field appears for the Remote modem only.
Vipersat Figure 2-13 TOS Switch Rules dialog Click on the Add button to add a new ToS rule, using the dialog shown in figure 2-14. • Name – Enter a user-defined text label for circuit identification. • Identifier – Enter an integer value in the range of 1 to 63. Entering a value of 0 will result in no switch. • Switch Type – Enter an integer value in the range of 64 to 254 at the prompt to inform the VMS what switching policy to use. Entering a value of 0 will result in no switch.
Vipersat Figure 2-14 Add TOS Rule dialog When one or more rules that appear in the list are selected, the Remove and Modify buttons become active. The Clear button is used to clear all rules from the list. DPC Dynamic Power Control (DPC) is a Vipersat feature that acts to regulate the transmit power of the Vipersat satellite modem, such that the specified receive signal level (Eb/N0) for the Vipersat unit(s) receiving the transmission is met.
Vipersat Figure 2-15 Dynamic Power Control dialog Enable Dynamic Power Control Activate the check box to Enable Dynamic Power Control for this unit. The SLM-5650A is shipped with this feature turned off (Disabled) to allow entrance link levels calibration during terminal setup. Speed-Up Eb/N0 Range The Speed-Up Eb/N0 Range parameter provides a means of decreasing the power adjustment period when an excessive delta occurs between the Eb/N0 receive level and the target value.
Vipersat STDMA Remotes via the Burst Map, and the DPC Target for these Remotes is automatically mapped to that address. Manually entering the Target IP Address is only necessary for modems that are SNMP managed Out-of-Band and will be utilizing the DPC feature. For InBand modems, the target addresses are handled automatically by the VMS.
Vipersat tion values are the highest achievable values as determined from the link budgetary calculations performed for this site. Figure 2-16 DPC Calibration dialog These parameter fields are read only in this dialog, and reflect the input settings made by the operator during modem configuration for DPC with either the Web GUI or the CLI.
Vipersat Figure 2-17 Home State dialog A superset of the Home State called the Modem Group Command (MGC) is displayed here, containing every base modem parameter including Vipersat. The Home State consists of both the modulator parameters and the demodulator parameters. Click on the Mod and Demod menu items for configuration. Mod The transmit parameter settings for the Modulator home state are shown in figure 2-18.
Vipersat Figure 2-18 Modulator Home State dialog Demod The receive parameter settings for the Demodulator are shown in figure 2-19.
Vipersat Note that the valid range for the Data Rate will vary depending on the Modulation Type and Coding Rate. When operating in Vipersat mode, the Coding Type must be set to Turbo and Coding Rates of 1/2, 2/3, and 1/1 are not valid.
Routing Routing Routing in a Vipersat Network SLM-5650A Modem Routers operating in Vipersat mode do not use the Multipoint, Point to Point, or Bridge network modes described in the SLM-5650A Installation and Operation Manual. There is no HDLC address in a Vipersat network; instead, the SLM-5650A role designation — Hub or Remote, Expansion unit or not — determines routing rules that prevent multicast loops. This simplifies the configuration of a Vipersat network.
R o ut i n g 1. From the tree menu, select Routing to open the Static Routes dialog. The static routing configuration for a typical Hub unit is shown in figure 2-20. Figure 2-20 Static Routes: Hub dialog 2. Click on the Add button to create the first route that will define the default gateway (figure 2-21). Figure 2-21 Add Static Route dialog In a Hub configuration, the default route will typically point to a router on the same LAN as the SLM-5650A Hub unit.
Routing In a Remote configuration, the default route will typically point to the satellite modem (WAN) used for communications back to the Hub. 3. Enter the Destination IP Address, the number of Subnet Bits in the subnet mask, the Description of the route (GW), the route Interface (LAN or WAN), and either the Next Hop address (LAN interface) or the HDLC Address (WAN interface). The system administrator can supply this information, if necessary. In a Hub role, for example, enter the name of the route (e.g.
R o ut i n g Figure 2-22 Open Shortest Path First dialog With the exception of Topology (Mesh/Star), the parameters on this page are used to configure the standard implementation of OSPF. To activate the OSPF feature for this modem, click in the Enable OSPF check box and set the parameter fields as described below. For the majority of networks, the default settings are recommended.
Routing Transmit Delay The Transmit Delay parameter sets the time period before transmitting the LSA. The default value is 1 second. Cost The Cost setting represents the link cost for the specified interface. This value is embedded in the router’s LSA metric field and used for SPF calculation. Default value is 65535. Range is 1-65535. Hello Interval The Hello Interval parameter is the timer value for sending the Hello packet on the specified interface.
R o ut i n g Default value is 40 seconds. Range is 1-65535. Authentication Key Setting the Authentication Key requires that all OSPF packets be authenticated, guaranteeing that only trusted routers will be allowed to propogate routing information. This can only be set when the Message Digest Key is not used. A simple password of up to eight characters can be specified.
LAN LAN Click on the LAN menu item to access and configure the local area network settings for this unit, as shown in figure 2-23. Figure 2-23 Local Area Network dialog Enable Flow Control Ethernet Flow Control allows TCP to manage limited network bandwidth and/ or data rate send/receive disparities. With flow control enabled, the receiving host will send a PAUSE frame (IEEE 802.3) to temporarily halt the data transmission when its buffer is overwhelmed.
LAN Enable Management High Security Feature This parameter is used to set the security level to either Low (unchecked) or High (checked). A High security setting will block CLI and Web GUI modem access, thus preventing unauthorized remote connections. Caution: Once this parameter is enabled and activated in the modem, neither the CLI nor the Web GUI can be used to disable High Security. Disabling must be performed using the modem’s front panel.
LAN Specify the port for VLAN assignment in the Select field (from 1 to 4). Specify the identity of the VLAN in the Id field (2 to 4095). ARP Address Resolution Protocol (ARP) is a low-level protocol used to map IP addresses (Network Layer) to physical MAC addresses (Link Layer) contained on the Ethernet hardware of routers and workstations. Click on the ARP menu item to set static address resolution protocol translations (figure 2-24). Here, an ARP mapping table can be created and modified.
LAN Figure 2-25 Add Static ARP dialog When one or more entries that appear in the list are selected, the Remove and Modify buttons become active. The Clear button is used to clear all entries from the list.
WAN WAN The WAN menu item is used to set Quality of Service parameters for the wide area network, and to specify the IP address to be used for multicasting internal messages over the satellite network. Figure 2-26 Wide Area Network dialog WAN-to-WAN Internal Multicast Address This multicast address is utilized by the Hub modem units for passing internal messages to the Remotes. Note that these messages are transmitted only over the satellite (WAN) network; they are never passed over the LAN.
WAN Quality of Service For network modems utilizing QoS, activate the Enable Quality of Service check box, then click on the Diff Serv sub-menu item to configure the Per-Hop Behavior categories. Differentiated Services Code Point (DSCP) The Comtech EF Data implementation of DiffServ uses all six bits of the DSCP (the first six bits of the ToS field in the IP Header) to define the Per-Hop Behavior categories, as shown in table 2-2.
WAN Service Rate This sets the bandwidth level for the Service Rate to be applied to user-defined classes of traffic flows. For the top two Per-Hop Behavior categories—Class Selector 6 and Expedited Forwarding—this value represents the maximum average bandwidth guaranteed for the traffic flow and is preset to the channel rate. For the Assured Forwarding Classes, this value represents the minimum average bandwidth guaranteed for the traffic flow and is configurable for Classes 2, 3, and 4.
WAN Class Selector 6 Class Selector Code Points are a set of reserved Per-Hop Behaviors that have a DSCP format of ‘xxx000’, where the three LSBs are 0. Class Selector 6 (CS6) is so named because it has a Precedence value of 6 (110). CS6 is the highest priority level in the DiffServ hierarchy for the SLM-5650A and is used exclusivly for management messages. Figure 2-27 Class Selector 6 dialog Set the Maximum Queue Depth, in bytes, to be used for this Class (range 1500-64000).
WAN Expedited Forwarding This class of traffic, forwarded with minimal latency, defines premium service and is recommended for real time traffic applications such as VoIP and video applications. Figure 2-28 Expedited Forwarding dialog Set the Maximum Queue Depth, in bytes, to be used for this Class (range 1500-64000).
WAN Assured Forwarding The Assured Forwarding PHB category serves general use traffic flows. This group defines four service levels (Class 1 through Class 4) and also uses the last three bits of the DSCP to define the Drop Probability or Precedence (Low, Medium, or High). The Drop Precedence determines which packets will most likely be dropped during periods of over congestion, similar to Weighted Random Early Detection (WRED).
WAN Default Default is pre-configured; the parameter fields for this Class are not editable.
NTP NTP The Network Time Protocol (NTP) settings are configured by clicking on the NTP menu item (figure 2-31). Figure 2-31 Network Time Protocol dialog To automatically synchronize with the Internet time, activate the check box for Enable NTP Server, then enter the NTP Address and the Time Zone for the modem location.
E v en t L o g Event Log Click on the Event Log menu item to access the logging level selection. (figure 2-32). Figure 2-32 Event Log dialog The Enable selection triggers the logging mechanism for the NP Interface only. It functions as a monitoring/troubleshooting aid to help determine the health of the interface, as well as troubleshoot any issues found in the field. By enabling the logging and setting the Level, system events are stored and reviewable through the NP Web interface.
I d e nt i f i c a t i o n Identification Click on the Identification menu item to display the current modem information that provides reference data for performing an upgrade (figure 2-33). Figure 2-33 Identification dialog The fields in this dialog are display only and cannot be edited.
