Summary

This article explains how configuration priorities are set between NetCloud Manager and the device administration pages, as well as how to determine the source of the router's configuration.


Description

For customers with NetCloud Manager (NCM), there are three main ways to edit a device's configuration: in NCM, through Group and Device configurations, and locally, through the router's own administrative page.

  • NCM Group configuration has the lowest priority.
  • NCOS local configuration has high priority.
  • NCM Device configuration has the highest priority.

The router's default configuration is used as a basis for comparison for configuration files. It is overwritten by any custom local configurations or NCM configurations.

The Group configuration in NCM is overwritten by both the custom local router configuration and the Device configuration in NCM.

The NCM Device and local router configurations are synonymous in most cases. When making a configuration change at the local level, the changes will then sync with the NCM Device level, and vice versa. The two scenarios where the NCM Device level configuration will override Local changes are:

  • when conflicting changes are made at both the Local and NCM Device level while the device is offline. Once brought online and checks into NCM, the NCM Device level changes will have priority.

  • when a new change is made locally while the NCM Device level configuration is still syncing the previous change. The new change will be overwritten by the last NCM Device level configuration once the sync completes.

In general, the preferred method for managing devices that are registered in NCM is through the Group configuration. If there are more specific settings needed for individual devices, use the Device configuration in NCM. For example, it is possible to make the administration password standard for an entire group, and then create individual SSIDs for each device - both through NCM.


Determining where a router gets its configuration

The individual config symbol found on the NCM Devices page indicates that the router is running a non-default configuration. The same symbol, when found on the NCM Groups pages tells us that the group contains one more routers that are running configuration settings that do not match the router default or the group configuration. (Tip: clicking the individual config symbol on the Groups page will automatically display all routers with unique configurations.)

The Configuration Summary option in NCM displays a color-coded output of the router's configuration. The target configuration displays the total sum of the different configurations the router is running:

  • settings in purple are pulled from the Group configuration in NCM
  • settings in green are pulled from the Device configuration in NCM
  • settings in grey exist only on the router's local configuration file, and are not synced to the Device configuration in NCM (possibly because the config sync was suspended, or the router went offline before syncing)
