VMware vCenter Update Manager network port requirements

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

vCenter Update Manager is installed as part of the installation process for vCenter Server. If you have an established VMware Infrastructure environment, you can use the same installer to add vCenter Update Manager functionality.

You can install vCenter Update Manager on the same machine as vCenter Server or on a different machine. Before you install vCenter Update Manager, gather the networking information (including the IP address and port number) about vCenter Server that vCenter Update Manager will use.

vCenter Update Manager 4.x/5.x/6.x/7.x/8.x

After the installation:

• vCenter Update Manager connects to vCenter Server on TCP port 80.
• ESXi/ESX hosts connect to the Update Manager Web Server listening on HTTP port 9084 for host patch downloads.
• vSphere Client initialization of the vCenter Update Manager plugin uses TCP port 9084 between the client and the vCenter Update Manager server.
• vCenter Update Manager connects to ESXi/ESX hosts on TCP port 80 and 902 for pushing virtual machine patches and host upgrade files.
  
  Note: vCenter Update Manager 5.0.x no longer supports patching virtual machines.
   
• The vCenter Update Manager Client plug-in connects to the vCenter Update Manager SOAP server listening on port 8084. It connects to the vCenter Update Manager Web server on HTTP (SSL) port 9087 for uploading the host upgrade files.

To obtain metadata, vCenter Update Manager must be able to connect to URL dl.broadcom.com, and requires outbound ports 80 and 443. See KB article "VCF authenticated downloads configuration update instructions."

If the default ports 80 and 443 are already in use by another application, the alternate port numbers used by vCenter Update Manager should be within the range 9000-9100. VMware vCenter Update Manager automatically opens these ports for ESX host scanning and remediation.
