What is NSP access administration?
Introduction
This chapter describes NSP UI access requirements and best practices, and includes procedures for configuring global UI settings and client access.
Browser access to redundant NSP clusters
If you open a browser to the primary NSP URL in a DR deployment, the primary NSP sign-in page opens.
If you open a browser to the standby NSP URL, the browser is redirected to the primary NSP URL if the standby server is operational; otherwise, the browser shows the standby URL as unreachable.
Single-address DR NSP system access
To reduce the number of IP addresses that an NSP operator requires for access to the servers in a DR NSP deployment, you can use a reverse-proxy server to set one IP address for NSP access, regardless of which NSP cluster is active.
See How do I enable single-address DR NSP system access? for proxy-server configuration information.
Best practices for NSP UI access
Some HTTP errors or stalled user sessions can be avoided by adhering to the following best practices:
-
The NSP UI is supported on the latest version of Google Chrome. Although other browser types are supported, Chrome is the preferred browser. For information about additional browser support, see the NSP Planning Guide.
-
It is recommended to use the NSP menu for access to NSP functions, as user-created links to the functions may be broken by a server activity switch or software upgrade.
-
Before signing in as a different user, close all other NSP tabs and sign out of the last tab.
-
If multiple NSP tabs are open in one browser, close all other NSP tabs before signing out of the last NSP tab; do not just close the browser.
-
In the event of an NSP server activity switch or shutdown, close all browser tabs; you can sign in again when the server returns to service.
OSS API access to NSP functions
NSP functions publish RESTCONF API URLs for access to managed resources and internal NSP services. Each domain documents the available URLs, which are accessible through a browser to clients such as OSS applications.
See the Network Developer Portal for information about OSS access to the NSP using RESTCONF APIs.
User documentation access
You can open the NSP Help Center from each NSP view by clicking on the ? icon. The Help Center provides domain-specific help and access to other NSP documentation.
Session connection loss
NSP UI sessions that are terminated by a connection loss may require up to two minutes to reset after the connection is restored. In the interim, the UI may seem to function, but executing a command results in a browser error. The condition persists until an automated system function clears the former session.
Keyboard-based navigation
You can use the keyboard to navigate and interact with many NSP views. Keyboard navigation allows you to highlight and select interactive elements using keystrokes instead of a pointing device.
The following table lists the accessibility options.
