One of the important issues in designing networks is knowing the ports needed to work with various services and software. In this article, we will explain the important ports of Applience vCenter and each application.
VMware vCenter requires the correct operation to send information to all hosts, and on the other hand, it will receive data from all vSphere Clients (or web clients).
So, in the following, we'll glimpse all the ports we need, as well as explain what vCenter uses.
Port 80 is used in vCenter like most software to create HTTP connection. Of course, in vCenter, all requests received via Port 80 will be redirected to Port 443. That's why if you accidentally enter the address instead of HTTPS with HTTP, you will automatically connect to HTTPS.
The port is the default vCenter that receives vSphere Client requests. If you change this default port, when connecting to the vCenter via vClient, you must enter the port address in addition to the IP. For example: 192.168.1.1:3333
The default port is to send information to servers (hosts) under management. Managed hosts also send the Heartbeat signals to the vCenter via the UDP protocol on the same port 902.
Please note that this port should be open to all equipment that exists between your hosts and vCenters in different parts of the organization. (This equipment includes routers and firewalls)
And finally, vSphere Client uses the same port to run the virtual machine console! (This task is handled by the 903 on the Windows vCenter)
Port 514 and 1541
Both ports are used to access vSphere Syslog Collector Server. 1541 does this by using an SSL certificate.
Ports 9090 and 9443
The port 9090 for the HTTP service on vSphere Web Client and port 9443 is also for access to the HTPPS in the Web Client.
This port is also one of the most popular and most used ports for access to vCenter. Access to port 22 is required for SSH access to the VMware vCenter Appliance.
