The Cloud Service Manager (CSM) is a core component of NSX Cloud.
After installing NSX Manager, install CSM by following the same steps as for installing NSX Manager and selecting nsx-cloud-service-manager as the VM role. See Install NSX Manager and Available Appliances for instructions.
You can deploy CSM in the Extra Small VM size or higher, as required. See NSX Manager VM and Host Transport Node System Requirements for details.
Ports and Protocols
For a list of ports and protocols required for inbound and outbound access for CSM, see https://ports.esp.vmware.com/home/NSX.
NTP Server Configuration
Many features require that CSM has a valid NTP server entry. You can configure the NTP server at the time of installing CSM or later. Also see Configuring NTP on Appliances and Transport Nodes in the NSX Administration Guide for other options for configuring NTP.
