Modify Pathfinder Settings From the Pathfinder CLI
The component-specific Pathfinder settings previously maintained in the northstar.cfg file are maintained in an internal cache and can be modified by using the Pathfinder CLI. The Pathfinder CLI is very similar to the Junos OS CLI.
Certain bootstrap and infrastructure configuration settings continue to be maintained in the northstar.cfg file.
If you are not already familiar with the Junos OS CLI, see Junos OS CLI User Guide which covers:
Accessing operational and configuration command modes, and switching between modes.
The concept of command hierarchies.
Navigation among hierarchy levels.
Getting help on command syntax including how to display all possible completions for a partial command.
Helpful keyboard sequences including command completion shortcuts.
Committing or backing out of configuration changes.
You can also modify the Pathfinder settings from the GUI. See Modify Pathfinder Settings From the GUI.

Modify Pathfinder Configuration Settings
Table 1 lists the Pathfinder configuration settings most likely to require modification. It is not a complete listing of all the available settings.
The following configuration settings are not supported currently. We strongly recommend that you do not modify these settings:
Analytics
Health Monitor
Peer Engineering
Some Topology Server settings: element-state-mask, element-type-mask, use-safe-mode, do-not-use-davinci-device-model
Setting |
Command |
Description |
---|---|---|
port (NETCONF) |
set northstar netconf-connection-controller device-connection-pool netconf port |
Change the default port for NETCONF from 830. In some installations, port 22 is preferred. |
exec-pace-rate (EPE) |
set northstar peer-engineering egress application exec-pace-rate |
Set the maximum rate (in calls per second) at which the egress peer engineering (EPE) Planner executes Pathfinder REST API calls that change the network. Note:
Currently, this setting is not supported. |
target-tag-cookie-range-start (EPE) |
set northstar path-computation-server bgp-steering target-tag-cookie-range-start |
Set the starting number for path cookie allocation. EPE static routes added by Pathfinder are allocated an unused path cookie starting from the value specified here. |
target-tag (EPE) |
set northstar path-computation-server bgp-steering target-tag |
Set the target prefix for the PRPD filtering community. |
polling-interval (Multilayer) |
set northstar mladapter polling-interval |
Set the polling interval (in seconds) for interfaces without notification support. |
lsp-latency-interval (Analytics) |
set northstar path-computation-server lsp-latency-interval |
Set the interval (in seconds) for which the PCViewer calculates LSP delay and display the data in the Tunnels tab of the GUI (Network > Topology > Tunnels tab > View > Delay). |
include-interface-type (all tasks related to interfaces) |
set northstar config-server include-interface-type |
Set interface types that can be discovered on devices and that are to be used for traffic collection. The supported interface types are:
Note:
configServer publishes to all components only the interface types that you specify. The GUI and data collection only receive information about interfaces representing those interface types. If you modify this setting by clearing interface types that are already represented by interfaces in the Pathfinder model, those existing interfaces remain in the model. |
