Network Information Pane Bottom Tool Bar
The bottom tool bar in the Network Information pane has tools for navigating through the network element data, as well as Add, Modify, and Delete buttons for performing actions on elements.
The Add, Modify, and Delete buttons behave differently, depending on which type of element you are working with; these functions are not always allowed. When they are not allowed, the buttons are grayed out. The Modify and Delete buttons become enabled when an individual element row is selected, as long as the action is allowed on that element.
The tools in the Network Information pane bottom tool bar are available to help you navigate through rows of data, refresh the display, and change the number of rows per loaded page. These tools are especially useful for large models with many elements.
Table 1 describes the tools in the bottom tool bar. Not all of the tools are available for all element types (node, link, interface, and so on).
Tool or Button
Displays the first page of data.
Displays the previous page of data.
Page __ of <total pages>
Displays the specific page of data you enter.
Displays the next page.
Displays the last page.
Manually refreshes the data.
Downloads the table information to spreadsheet.
Opens a search criteria field. Enter the search criteria and click the Filter button on the far right of the field. The table and the topology display only the results of the search.
After a search, restores the topology to the full network display.
Click the down arrow to specify a grouping for the table contents.
Specifies the number of rows per loaded page.
Actions Available for Nodes
For nodes, Add is not a supported function. Modify is allowed and is optionally used to set or change the latitude and longitude of a node, change node properties, or add IP addresses.
Figure 1 shows the Properties tab of the Modify Node window. All of the fields on this tab can be modified.
Figure 2 shows the Location tab of the Modify Node window. NorthStar Controller uses latitude and longitude settings to position nodes on the country map, and also to calculate distances when performing routing by distance.
Enter latitude and longitude values using signed degrees format (DDD.dddd):
Latitudes range from -90 to 90.
Longitudes range from -180 to 180.
Positive values of latitude are north of the equator; negative values (precede with a minus sign) are south of the equator.
Positive longitudes are east of the Prime Meridian; negative values (precede with a minus sign) are west of the Prime Meridian.
Enter a site name in the Site field.
Figure 3 shows the Addresses tab of the Modify Node window.
The NorthStar Controller supports using a secondary loopback address as the MPLS-TE destination address. In the Addresses tab of the Modify Node window, you have the option to add destination IP addresses in addition to the default IPv4 router ID address, and assign a descriptive tag to each. You can then specify a tag as the destination IP address when provisioning an LSP.
A secondary IP address must be configured on the router for the LSP to be provisioned correctly.
Click Add to create a new line where you can enter the IP address and the tag.
Click Submit to complete the node modification.
Actions Available for Links
For links, Add is not a supported function. Modify is available and is primarily used in support of the Multilayer feature. Sometimes, when interlayer links are initially loaded into the model, only the source is known. In those cases, you can select Node Z (the remote node name) from the drop-down menu, and enter IP Z (the corresponding IP link end on Node Z) to manually connect the Transport Layer to the IP Layer. You can also specify the Type of the link and add your comments for reference. On the Advance tab, you can specify Delay and Admin Weight values for the link. On the User Properties tab, you can add properties not already defined. The Properties tab of the Modify Link window is shown in Figure 4.
Actions Available for Tunnels
For tunnels, Add, Modify, and Delete are available functions for PCE-initiated tunnels. Delegated tunnels cannot be added or deleted.
Figure 5 shows the Provision LSP window.
You can also reach the Provision LSP window from the Applications menu in the top menu bar by navigating to Applications>Provision LSP. See Provision LSP for descriptions of the data entry fields in this window.
The Modify LSP window has the same data entry fields as the Provision LSP window (not all of which can be modified).
Actions Available for SRLGs
Shared Link Risk Group (SRLG) information can come from two sources:
The information from these sources is merged and presented in the web UI. You can also Add, Modify, and Delete user-defined SRLGs.
Actions Available for Maintenance Events
Add, Modify, and Delete are available functions in the Network Information pane for maintenance events. You can also reach the Add Maintenance Event window from the Applications menu in the top menu bar by navigating to Applications>Maintenance. See Maintenance for descriptions of the data entry fields in the Add Maintenance Event window.
The Modify Maintenance Event window contains the same fields as the Add Maintenance Event window.
You can access the Maintenance Event Simulation window by right-clicking in a maintenance event row and selecting Simulate.
Actions Available for Interfaces
Interfaces cannot be added, modified, or deleted from the network information table.
