This chapter describes the menus and commands of the SV+ network topology toolsets. The N/W Topology map is presented when you select the Topology icon of the SV+ Desktop window.
Topology tools include the commands contained within the menus at the network topology menu bar as well as those generated from selected nodes. Other tools are the alarm indicators (sound and color) which provide timely indications of network status.
IPX/BPX networks can contain ten types of icons, each of which is displayed on the topology map with its name or node ID. You select node-specific icons with the N/W Topology - Utility - Icons... menu which is described later in this chapter. You can also place an icon on your map to represent the INS/DAS.
To select objects on the Network Topology map, position the cursor on the object and click the left mouse button. If you click on an IPX, BPX, or access node, you connect to that node and an Administration Window is displayed.
If you click (without movement) on a group, the system zooms and the display centers on the members of the group.
The left mouse button is also used to select menus from the menu bar, and for general window manipulation (shrinking, expanding, and stacking).
Press the left mouse button and move the mouse over the map area you want to zoom into. When you release the mouse button, the display zooms into the region that you selected.
Zoom back out by selecting the Reset command under the Utilities pull-down menu.
To move objects on the topology map, select an object and drag the pointer with the left mouse button, then release it at the desired destination. Clicking and dragging does not connect to nodes; it simply moves and repositions the object on the screen.
The move object function is used to rearrange objects on the StrataView Plus Topology map. You need to use this function whenever you add new nodes to your network because the node icons cluster into the left corner of the screen until you move them. Once an object is moved, you can use the Save command in the Utility pulldown menu to save the current display arrangement.
Press and hold the middle mouse button to move (pan) the topology display. The amount and direction of the pan is controlled by how long and in what direction you drag the mouse.
When you click on a trunk, a window appears with user-defined information, such as carrier data, trunk id and type, etc. If there is no existing information for the trunk you selected, a comment can be added to the displayed text box. Selecting an existing comment allows you to edit or delete it. If the line is a multiple trunk bundle, the line will appear thicker on the topology map. When you click on this thick line, a dialog box appears with a list of existing trunk connections. Select the desired trunk for information display, and the dialog box that allows you to enter trunk information appears.
The following sections provide information on working with the topology display pulldown menu functions. The descriptions that follow are presented in order as you look at the pulldown menus from left to right in the Network Topology window.
Use this menu to exit the Network Topology Map without shutting down StrataView Plus processes. StrataView Plus continues to collect data even though the workstation screen is cleared of the topology Windows.
Use this menu to install an access node on the topology map. This menu presents the Access - Add Window.
Name | Type the name of the access node that you are adding. If this field is left blank, the window will be untitled. |
| Comment | Type a description of the equipment (such as feeder MUX). |
| Port | Type the UNIX logical device that is attached to the access node. (such as /dev/tty03 for an RS-232 interface, or /dev/ttyDD for a LAN interface). |
| Speed | Type the baud rate for the (async) port. Acceptable values are: 300, 1200, 2400, 9600, or 192000 bps. |
| Phone # | Type a phone number for the system to use when autodialing the auxiliary equipment, or leave this field blank for direct connection. |
Use this menu to remove a selected access node from the topology map. The Access-Delete command converts your cursor to a skull-and-crossbone symbol. Use this cursor to select the node targeted for deletion.The Confirm Deletion dialog window appears following your selection. Click he OK button on this window to complete the delete process.
Use this menu to either create a new group or to add a selected network device to an established group.
This menu converts your cursor to an umbrella symbol. With this cursor, select the network icon targeted for grouping. The Add Group dialog box then appears.
Name of new group: | Type the name by which the group can be identified on the topology map. When OK'd, your entry is immediately displayed on the Network Overview map, and recorded at the SV+ Event Log. |
Use this menu to separate the members of a group. Following the Group-Delete operation, each member that formerly belonged to the selected group is displayed as a separate object on the topology map.
This menu converts your cursor to a skull-and-crossbones symbol. With this cursor, select the group targeted for deletion and click OK on the confirmation dialog box to complete the operation.
Use this menu to display the interface devices attached to the selected routing node. To present the Display Shelves dialog window, click on a node within the topology map prior to selecting the Display Shelves...menu.
Use this menu to present the Node Administration window. This window provides a virtual terminal session to enable command line interface activities to a selected node. You can also use this window to interface with selected access devices, such as a FastPAD feeder MUX and an AIP, that are attached to network nodes The commands acceptable in this window are documented in the Command Reference Manual.
Use this menu to display the current level of software on each node, its IP address, and whether or not it is in the process of being upgraded.
Use this menu to toggle the display of the background map to either ON or OFF. If you want to change the type of map shown in your topology work area, use the Map Select menu.
N/W Topology - Map - Select Menu
Use this menu to define the background map display for your topology window. This menu presents the Select Map dialog window.
Items | Use this area to view the available maps you can select for your topology map background. Left click on the name of a map to begin the selection process. |
| Selection | This field displays the name of your selection. You can confirm this selection by clicking the OK button, or abort by clicking the Cancel button. |
Use this menu to define the icons you use to depict network objects on your topology map. Selection of an icon type globally affects established icons for specific network objects.
If you want to save this selection, click on Save in the Utility pulldown menu. This will preserve the selection in the event that you quit StrataView Plus.
Use this menu to force a complete update of the workstation screen. The reset function redraws the display and restores zoom to the default level.
Use this menu to toggle SV+ operation to either protocol mode or TRM mode
| Protocol mode | provides all StrataView Plus capabilities and is the correct operation mode for day-to-day activities. You can verify that StrataView Plus is operating in StrataView Plus mode by looking for SV+ in the upper line of the Node Administration screen. |
Use this menu to store StrataView Plus configuration information to the database without exiting StrataView Plus. A save operation preserves the current map, disposition of the background map, and current configuration of the network objects.
Use this menu to view the list of current software images. The images shown in the dialog window are available from the SV+ hard disk.
During IPX/BPX node initialization, the node attempts to locate the correct version of software or firmware, or image, from Flash EPROM. If the image is not located there, the SV+ workstation is then interrogated. Failure to find the image at the SV+ workstation results in interrogation of other nodes on the network. If the system is unable to locate the image, you may need to download or restore the image.The Images menu enables software and firmware downloads and restoration of previous BPX/IPX configurations to your BPX/IPX nodes. Downloading commands are issued from the Node Administration window. Contact StrataCom ISC for further information.
The StrataView Plus Downloader simplifies the distribution of software and card firmware to IPXs and BPXs in the field. This is accomplished by providing download capability from a single point to an entire network.
IPX and BPX nodes can download software from one of the following three places:
To store an BPX/IPX software release (image), you copy the IPX (NPC or PCC) or BPX (BCC) software release from tape to the SV+ workstation hard disk. A list of the stored software images can then be viewed from the Network Topology window via the Images SW/FW menu. Images can then be loaded to system nodes by using commands at the Node Administration window.
Use this menu to present the Configuration Name dialog window. Use this window to view IPX BRAM configurations that may be used to restore a previous or current IPX configuration.
Use this menu to set the frequency of alarm beeps. This menu presents the Audible Alarm Configuration dialog window.
StrataView Plus generates audible alarms as a result of either topology or statistics collection alarms.The default time for how long the alarms will continue to sound may be set. The alarms may also be turned on or off.
Alarm Interval Default: 60 | Type the number of seconds to pass between alarm sounds |
| Enable
Default: OFF | Toggle this button to ON to hear alarm sounds.
Toggle this button to OFF to remain silent during alarms. |
| Continuous
Default: OFF | Toggle this button to ON to bypass the alarm interval setting, and to sound an alarm continuously until acknowledged. |
Use this menu to silence an alarm and to quickly find a description of the source problem. This menu presents a dialog box similar to that shown below. By left clicking on the OK button, you silence an also be turned on or off.
The main tool for monitoring the status of your network is the StrataView Plus Network Topology Map. By matching the displayed node and trunk color codes to specific alarm conditions, you can see what is occurring throughout the network.
When the topology display is updated, the node and trunk icons change colors to reflect the latest alarm events.
Green | Normal |
| Yellow | Minor alarm |
| Red | Major alarm |
| Brown | Node unreachable |
A typical map display may contain multiple alarm indications.
StrataView Plus continuously monitors the network topology status and updates the Network Topology Map display.
The network nodes send network status messages to the StrataView Plus workstation as the events occur. Any discrepancy between the dynamic update messages and the StrataView Plus workstation's internal topology information causes the workstation to repoll the network for a new topology, and then update the workstation database. Complete topology polling also occurs when the workstation is first brought online.
