Port numbers that must be open for Site Recovery Manager, vSphere Replication, and vCenter Server (1009562)

Symptoms

Site Recovery Manager (SRM) and vSphere Replication can experience problems if the required network ports are not open.

• Site Recovery Manager fails to establish site pairing due to connection termination over port 8095.
• Site Recovery Manager connection to remote site breaks frequently.

Purpose

In an SRM or vSphere Replication deployment, both the protected and recovery sites must be able to resolve their connected vCenter Server by name. The respective ports must be open on both sites for uninterrupted communication.

For the list of default ports that all VMware products use, see TCP and UDP Ports required to access vCenter Server, ESXi/ESX hosts, and other network components (1012382).

Resolution

You must ensure that all the required network ports are open for SRM and vSphere Replication to function correctly.

• Site Recovery Manager 5.x and vSphere Replication 1.0.x and 5.x network ports
  
  
  • vCenter Server and ESXi 5.x network ports that SRM requires
  • SRM Server 5.x network ports
  • vSphere Replication Appliance 5.x network ports
  • vSphere Replication Management Server 1.0.x network ports
  • vSphere Replication Server 1.0.x and 5.x network ports
  • Network ports that must be open between the SRM and vSphere Replication protected and recovery sites
• Site Recovery Manager 1. to 4.1.x Network Ports

General networking guidelines:

• When troubleshooting SRM and vSphere Replication pairing and testing issues, eliminate firewalls and security applications as a possible cause of the problem by temporarily disabling or removing the software or item in question.
• If you are using a VPN adapter such as SonicWALL or Juniper, ensure that the timeout setting is set to the maximum for any tunnel that is open on the required ports.
  

Site Recovery Manager 5.x and vSphere Replication 1.0.x and 5.x network ports

The different components that make up SRM and vSphere Replication deployments, namely vCenter Server, SRM Server, the vSphere Replication appliance, and vSphere Replication servers, require different ports to be open.

vCenter Server and ESXi 5.x network ports that SRM requires

SRM and vSphere Replication require certain ports to be open on vCenter Server:

vSphere Replication Appliance 5.x network ports

The vSphere Replication appliance requires certain ports to be open. In SRM 5.1 and later and vSphere Replication 5.x, vSphere Replication is shipped as a combined appliance that contains both the vSphere Replication management server (VRMS) and a vSphere Replication server. SRM 5.x allows you to deploy additional vSphere Replication servers.

Note: vSphere Replication management servers must have NFC traffic access to target ESXi hosts.

Default Port	Protocol or Description	Source	Target	Endpoints or Consumers
80	TCP	vSphere Replication appliance	Remote vCenter Server	All management traffic to the vSphere Replication appliance goes to port 80 on the vCenter Server proxy system.
80	HTTP	vSphere Replication appliance	Remote ESXi host	Used to establish the connection before initial replication starts
902	TCP and UDP	vSphere Replication server in the vSphere Replication appliance	Remote ESXi host	Used by vSphere Replication servers to send replication traffic to the destination ESXi hosts.

The vSphere Replication appliance requires certain ports to be open. SRM 5.0.x includes vSphere Replication 1.0.x. In vSphere Replication 1.0.x, vSphere Replication consists of a vSphere Replication management server (VRMS) appliance and one or more vSphere Replication servers.

Note: vSphere Replication management servers must have NFC traffic access to target ESXi hosts.

Default Port	Protocol or Description	Source	Target	Endpoints or Consumers
80	TCP	vSphere Replication management server	Remote vCenter Server	All management traffic to the vSphere Replication management server goes to port 80 on the vCenter Server proxy system.

vSphere Replication Server 1.0.x and 5.x network ports

The vSphere Replication 5.x appliance contains a vSphere Replication server. You can deploy additional vSphere Replication servers if you use vSphere Replication 5.1 with SRM 5.1 or if you use vSphere Replication 5.5. You cannot deploy additional vSphere Replication servers if you use vSphere Replication 5.1 without SRM.

SRM 5.0.x includes vSphere Replication 1.0.x. In vSphere Replication 1.0.x, vSphere Replication consists of a vSphere Replication management server (VRMS) appliance and one or more vSphere Replication server appliances that you deploy separately from the VRMS.

If you deploy additional vSphere Replication servers, ensure that the subset of the ports that vSphere Replication servers require are open on those servers.

Default Port	Protocol or Description	Source	Target	Endpoints or Consumers
902	TCP and UDP	vSphere Replication server	Remote ESXi host	Traffic (specifically the NFC service to the destination ESXi servers) between the vSphere Replication server and the ESXi hosts on the same site.
