Known issues

Return to top

After upgrading to NCM 2020.2.5, attempting to open an NCM page returns an error

Issue: In some environments, after upgrading to NCM 2020.2.5, 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 to resolve it:

  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 to NCM 8.0 or later, 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.
