We started this chapter by looking at NSX Manager settings. We looked at many settings including changing the date and time, configuring a syslog server, configuring DNS servers, gathering tech support logs, and SSL certificates configuration. We then looked at backing up and restoring our NSX Manager, and configuring our NSX Manager with an active directory. NSX Controller operations described how to change NSX controller passwords, which is a best practice, and also talked about how to download tech support logs for controllers and configure them with a syslog server. Finally, we looked at reviewing communication channel health between NSX Manager and all of its components.
