Add and Assign a LicenseYou can add and assign a license using the vSphere Web Client. Using the DashboardThe dashboard provides visibility to the overall health of NSX components in one central view. The dashboard simplifies troubleshooting by displaying status of different NSX components such as NSX Manager, controllers, logical switches, host preparation, service deployment, backup as well as edge notifications. Check Communication Channel HealthNSX checks on the status of communication between NSX Manager and firewall agent, NSX Manager and control plane agent, and control plane agent and controllers. NSX Controller ManagementYou can change the NSX Controller node configuration, including changing names, passwords, or configuring NTP. You can also download tech support information from the NSX Controller nodes. Controller Disconnected Mode for Multiple SitesController Disconnected Operation (CDO) mode ensures that the data plane connectivity is unaffected in a multi-site environment, when the primary site loses connectivity. You can enable the CDO mode on the secondary site to avoid temporary connectivity issues related to the data plane, when the primary site is down or not reachable. You can also enable the CDO mode on the primary site for the control plane failure. Change VXLAN PortYou can change the port used for VXLAN traffic. Customer Experience Improvement ProgramNSX participates in VMware’s Customer Experience Improvement Program (CEIP). About NSX LogsYou can configure the syslog server and view technical support logs for each NSX component. Management plane logs are available through NSX Manager and data plane logs are available through vCenter Server. Hence, it is recommended that you specify the same syslog server for the NSX component and vCenter Server in order to get a complete picture when viewing logs on the syslog server. Audit LogsAudit logs for operations tracked by a ticket includes the ticket ID. With the NSX ticket logger feature, you can track the changes you make with a ticket ID. System EventsSystem events are events that are related to NSX operations. They are raised to detail every operational event. Events might relate to basic operation (Informational) or to a critical error (Critical). Management System SettingsYou can edit the vCenter Server, DNS and NTP server, and Lookup server that you specified during initial login. NSX Manager requires communication with your vCenter Server and services such as DNS and NTP to provide details on your VMware Infrastructure inventory. NSX Backup and RestoreProper backup of all NSX Data Center for vSphere components is crucial to restore the system to its working state in the event of a failure. NSX Monitoring And Diagnostic ToolsNSX provides different tools that can help you to monitor, and collect data to diagnose any problem with your system.
