Home page of NSO Web UI.
The Home view is the default view after logging in. It provides shortcuts to Devices, Services, Config editor, and Tools.
Currently loaded Web UI extension packages are shown in this view under Packages. Web UI packages are used to extend the functionality of your Web UI, for example, to create additional views and functionalities. Examples are creating a view to visualize your MPLS network, etc.
Traverse and edit NSO configuration using the YANG model.
The Configuration editor view is where you view and manage aspects of your NSO deployment using the underlying YANG model, for example, to configure devices, services, packages, etc.
The Configuration Editor's home page shows all the currently loaded YANG modules in NSO, i.e., the database schema. In this view, you can also browse and manage the configuration defined by the YANG modules.
All NSO configuration is performed in this view. You can edit the configuration data defined YANG model directly in this view or get directed by the Web UI to this view.
An important component of Configuration Editor is the Configuration Navigator which you can use to traverse and edit the configuration defined by the YANG model in a hierarchical tree-like fashion. This provides an efficient way to browse and configure aspects of NSO. Let's say, for example, you want to access all the devices in your deployment and choose a specific one to view and configure. In the Configuration Editor, you can do this by typing in ncs:devices in the navigator, and then choosing further guided options (automatically suggested by the Web UI), e.g., ncs:devices/device/ce0/config/....
As you navigate through the Web UI, the Configuration Navigator automatically displays and updates the path you are located at.
Use the TAB key to complete the config path.
When accessing an item (e.g., a device, service, etc.) using the Configuration Editor, the following tabs are visible:
Edit Config tab, to configure the item's configuration.
Config tab, to view configured items.
Operdata tab, to view the operational data relevant to the item (e.g., last sync time, last modified time, etc).
Actions tab, to apply an action to the item with specified options/parameters.
Depending on the selection of the tabs mentioned above, you may see four additional tabs in the Configuration editor view:
Widgets tab, to view the data defined by YANG modules in different formats.
None tab.
Containers tab, to view container-specific information from the YANG model.
List tab, to view list-specific information from the YANG model.
To exit back to the home page from another path, click the home button.
Click the up arrow to go back one step to the parent node.
To fetch information about a property/component, click the info button.

: Used to perform upgrades to the packages running in NSO.
: Used to manage a High Availability (HA) setup in your deployment.
: Shows current alarms/events in your deployment and provides options to manage them.
: Shortcut to the Commit Manager.
: Used to run compliance checks on your NSO network.
The Insights view collects and displays the following types of operational information using the /ncs:metrics data model to present useful statistics:
Real-time data about transactions, commit queues, and northbound sessions.
Sessions created and closed towards northbound interfaces since the last restart (CLI, JSON-RPC, NETCONF, RESTCONF, SNMP).
Transactions since last restart (committed, aborted, and conflicting). You can select between the running and operational data stores.
Devices and their sync statuses.
CDB info about its size, compaction, etc.
In the Package upgrade view, you can load custom packages in NSO.
In the Package upgrade view, click Browse files to select a new package (.tar or .tar.gz) from your local disk.

The High Availability view is used to visualize your HA setup (rule-based or Raft).
The Alarm manager view displays current alarms in the system. The alarms are categorized as criticals, majors, and minors and can be filtered by device.
The Commit manager displays notifications about commits pending to be approved. Any time a change (a transaction) is made in NSO, the Commit Manager displays a notification to review the change. You can then choose to confirm or revert the commit.
Transactions and Commits
Take special note of the Commit Manager. Whenever a transaction has started, the active configuration data changes can be inspected and evaluated before they are committed and pushed to the network. The data is saved to the NSO datastore and pushed to the network when a user presses Commit.
Any network-wide configuration change can be picked up as a rollback file. The rollback can then be applied to undo whatever happened to the network.
Review the available changes appearing as Current transaction. If there are errors in the change, the Commit Manager alerts you and suggests possible corrections. You can then fix them and press Re-validate to clear the errors.
Click Revert to undo or Commit to confirm the changes in the transaction.
Start a transaction to load or save configuration data using the Load/Save option which you can then review for commit. The following tabs are available:
Rollback, to load data that reverts an earlier change.
Files, to load data from a local file on your disk.
Paste, to load data by pasting it in.
Save, to save loaded data to a file on your local disk.
In the Commit manager view, the following tabs are shown.

Operate NSO using the Web UI.
The NSO Web UI provides an intuitive northbound interface to your NSO deployment. The UI consists of individual views, each with a different purpose, such as device management, service management, commit handling, etc.
The main components of the Web UI are shown in the figure below.
The UI works by auto-rendering the underlying device and service models. This gives the benefit that the Web UI is immediately updated when new devices or services are added to the system. For example, say you have added support for a new device vendor. Then, without any programming requirements, the NSO Web UI provides the capability to configure those devices.
It's important to realize that the bulk of concepts and configuration options in Web UI are shared with the NSO CLI. The rest of the documentation covers these in detail. You need to be familiar with the fundamental concepts to work with the Web UI.
All modern web browsers are supported and no plug-ins are needed. The interface itself is a JavaScript Client.
By default, the Web UI is accessible on port 8080 of the NSO server for an NSO Local Install and port 8888 for a System Install. The port can be changed in the ncs.conf file. A user must authenticate before accessing the (web) UI.
Log in to the NSO Web UI by using the username and password provided by your administrator. SSO SAML login is available if set up by your administrator. If applicable, use the SSO option to log in.
Log out by clicking your username on the top-right corner and choosing Logout.
Access the help options by clicking the help options icon in the UI banner. The following options are available:
Online documentation: Access the Web UI's online help.
Config editor help: Access help on using the configuration editor.
NSO version: Information about the version of NSO you are running.
In the Web UI, supplementary help text, whenever applicable, is available on the configuration fields and can be accessed by clicking the info icons.
Hide and display the columns of your choice by using the column selection icon.
Click the add button.
Using the run action button, select the desired service action.
