Proxmox Networking:

• Log in to the Proxmox web interface or CLI as a user with administrative privileges.

• Click on the "Datacenter" node in the left-hand pane, then click on the "Network" tab.

• Click on the "Create" button to add a new network interface.

• Select the type of network interface you want to create (e.g., Linux Bridge or Open vSwitch), then provide a name for the interface.

• Configure the network settings for the interface, including IP address, subnet mask, and gateway. You can also configure VLANs and firewall rules at this point.

• Click "OK" to save the network interface.

• Repeat the above steps to create additional network interfaces as needed.

Proxmox Clustering:

• Log in to the Proxmox web interface or CLI as a user with administrative privileges.

• Click on the "Datacenter" node in the left-hand pane, then click on the "Cluster" tab.

• Click on the "Create" button to add a new cluster.

• Provide a name for the cluster and specify the IP address of the cluster manager.

• Create a shared storage volume that all nodes in the cluster can access. This can be done using a SAN, NAS, or other storage device.

• Add additional nodes to the cluster by specifying their IP addresses and joining them to the cluster.

• Configure high availability (HA) settings for virtual machines and containers. This can be done by enabling HA in the settings for each virtual machine or container.

• Configure load balancing settings for the cluster. This can be done by setting up load balancers and configuring the cluster to use them.

• Monitor the cluster for performance and issues using the Proxmox web interface or CLI.
