Important: Orion Platform 2020.2.6 includes updated password policies that impact individual Orion accounts. After you upgrade to NCM 2020.2.6, all passwords for individual Orion accounts will expire in 30 days. To learn more, see the Orion Platform 2020.2.6 Release Notes.

NCM 2020.2.6 offers the following security improvements.

NCM 2020.2.6 is an Orion Platform product, and runs on Orion Platform 2020.2.6. See Orion Platform 2020.2.6 Release Notes.

FIPS-compliant encryption algorithms

If 'Any' is specified as the Encryption Algorithm on a device's Properties page and the device is configured to be FIPS-compliant, NCM uses only FIPS-compliant algorithms for SSH communications with that device.

Node limitations checked when a user manually executes an NCM job

In previous versions of NCM, when a job was executed (either by a schedule or manually), NCM checked the limitations of the job owner to determine which nodes the job ran on.

After an upgrade to NCM 2020.2.6:

  • If a job is executed by a schedule, the behavior is the same: NCM checks the limitations of the job owner to determine which nodes the job runs on.

  • If a job is executed manually, NCM checks the limitations of the user who manually executed the job to determine which nodes the job runs on.

For example, an Administrator creates a job, selects Node 1 and Node 2, and schedules the job. When the job runs as scheduled, it runs on both Node 1 and Node 2. Another user has a limitation that excludes Node 1. If that user executes the job manually, the job runs only on Node 2.

Users cannot view job logs for restricted nodes

If limitations prevent a user from accessing a node, the user will no longer be able to view NCM job logs for jobs that ran on the node.

For example, a job runs on 10 Cisco nodes and 10 Palo Alto nodes. A user has a limitation that excludes all Palo Alto nodes. When the job runs after an upgrade to NCM 2020.2.6, that user will be able to view the job logs on the 10 Cisco nodes but not on any of the Palo Alto nodes.

After an upgrade to NCM 2020.2.6, users can view job logs as described below:

  • Existing job logs (that is, logs for jobs executed before the upgrade) can be viewed only by users with Orion Administrator rights. Therefore, immediately after the upgrade, users without Orion Administrator rights will not be able to view any job logs.

  • Logs for jobs executed after the upgrade can be viewed only if the user can access the node on which the job ran. As described previously, users cannot view job logs for jobs that ran on a restricted node.

  • If a node is deleted, NCM can no longer determine whether a user had limitations that would have restricted access to that node. Therefore, only users with Orion Administrator rights can view logs for jobs that ran on a deleted node.

    When a node is deleted, logs associated with that node are not automatically deleted. You can manually delete job logs, or schedule the Default Database and Archive Maintenance job to automatically purge older job logs.

Requirements to view, create, and manage jobs

If NCM Configuration Management Approval is not enabled, users with the NCM role of WebUploader or higher can now view, create, and manage NCM jobs. In earlier versions, the NCM role of Engineer or higher was required.

If NCM Configuration Management Approval is enabled, requirements to view, create, and manage jobs have not changed. See Create and manage NCM jobs for details.

Node limitations affect which nodes a job runs against and which job logs users can view, as described in the previous sections.

Requirements to view job logs for NCM Approval Requests

Users with the NCM role of WebUploader can access the Manage My NCM Approval Requests page, and they can view the jobs that were created when they scheduled the execution of a config change template. However, for WebUploaders, the History column does not display a link to view the job log. The NCM role of Engineer or higher is required to view job logs if NCM Configuration Management Approval is enabled.

Requirements to manually update policy compliance report information

The NCM role of WebUploader or higher is required to update the information about policy violations displayed in policy compliance reports. On the Compliance Policy Reports page, the Update All or Update Selected button is disabled for users with the WebDownloader or WebViewer roles.

Change to the SolarWinds SWIS API

The SWIS property JobLog from Cirrus.NCM_NCMJobs has been removed. To retrieve secured job logs, invoke GetJobLog from the same entity.

How to upgrade

Use the SolarWinds Orion Installer to upgrade your entire Orion deployment (all Orion Platform products and any scalability engines).

If you are upgrading from NCM 8.0 or later, you can upgrade your entire Orion deployment from the My Orion Deployment page. Downloading the Orion Installer is no longer necessary.

Fixed issues in NCM 2020.2.6

Return to top

NCM 2020.2.6 fixes the following issues.

Case Number Description
00556336, 00747181, 00753638, 00810156

Maintenance jobs complete successfully and no longer log Incorrect SQL syntax error messages.


NCM 2020.2.6 supports the key exchange algorithm diffie-hellman-group14-sha256. If a device is configured to use this algorithm, NCM connection attempts no longer fail with the message Connection refused.


A memory leak in login validations and manual config transfers is fixed.


In previous versions, a connection attempt would hang if NCM could not connect with the assigned connection profile and the Advanced Setting "Use auto-detect when assigned connection profile cannot be used" was selected. This issue is resolved.


After an upgrade, the Configuration Wizard no longer fails when the script UpdateMenuItem.sql runs.

00572106, 00631152

One or more downloads no longer fail if a config download job targets multiple devices that use TFTP (Trivial File Transfer Protocol) for downloads.


When configs are downloaded from a Palo Alto device with OS version 7 or later, NCM displays policy information in the Policies view of the Node Details page.

00456949, 00426616

When very large config files are stored in the NCM database, config searches no longer fail with an OutOfMemoryException error.

CUST-61214, 64005

Known issues

Return to top

Some functionality in SolarWinds Platform products cannot be accessed through Internet Explorer 11

Issue: If you use IE 11 to access NCM or other SolarWinds Platform products, some pages are not accessible or do not function correctly. These pages include (but are not limited to):

  • Manage custom properties
  • MIBs Management
  • Node status contributors
  • Manage Dashboards

Resolution/Work-around: If a page does not function correctly in IE 11, use a different browser to access the page.

After upgrading, attempting to open an NCM page returns an error

Issue: In some environments, after an upgrade to NCM 2020.2.6 or later, NCM pages cannot be accessed. When you attempt to open a page that includes NCM data, such as the Node Details page, the message Request timed out is displayed. This occurs because the SolarWinds.NCM.BusinessLayerPlugin.dll.config file was not updated during the upgrade.

Resolution/Work-around: If you encounter this issue, complete the following steps on the main polling engine and all additional polling engines (APEs).

  1. Create a backup copy of the following file, and then remove the file: 

    C:\Program Files (x86)\SolarWinds\Orion\NCM\SolarWinds.NCM.BusinessLayerPlugin.dll.config

  2. In the Windows Control Panel, open Programs > Programs and Features.

  3. Right-click SolarWinds Orion Network Configuration Manager and choose Repair.

    The repair process updates the SolarWinds.NCM.BusinessLayerPlugin.dll.config file.

Permissions required to modify policy reports

Issue: When you configure NCM security settings, you can select the following option:

Only NCM admin can modify compliance policy reports

If you select this option, the NCM Administrator role is required to manage policy reports through the user interface. However, if you use the SolarWinds API to manage policy reports, both the NCM Administrator role and Orion administrator rights are required.

Resolution/Work-around: Grant Orion administration rights to the account that will manage policy reports using API calls.
NCM does not show current information about overlapping ACL rules after an upgrade
Issue: After you upgrade from NCM 7.9 or earlier, NCM does not display current information about shadowed or redundant access control list (ACL) rules. Older information is displayed.
Resolution/Work-around: Download the configuration files from your Cisco ASA and Nexus devices. After you download the config files, NCM displays current information about shadowed and redundant ACL rules.
