To configure Network Load Balancing (NLB) in vSphere, follow these steps:
1. Create a new distributed virtual switch (vDS) in the vSphere Web Client. Navigate to the Networking section and click on Add Networking.
2. Follow the prompts to create the distributed virtual switch. Choose the appropriate options for your environment.
3. Create a new distributed port group on the vDS for your NLB cluster.
4. Configure the IP addresses for your NLB hosts. Each host must have a unique IP address.
5. Add the NLB hosts to the distributed port group.
6. Create a new NLB cluster for the virtual machines you want to load balance. In the vSphere Web Client, navigate to the Networking section and click on Network Load Balancing.
7. Follow the prompts to create the NLB cluster. Choose the distributed port group you created in step 3.
8. Configure the cluster settings, including load balancing method, affinity, and health check settings.
9. Add the virtual machines you want to load balance to the cluster.
10. The NLB cluster is now configured and ready to use.
Note: For NLB to work in vSphere, the virtual machines must be running on hosts that are part of the same NLB cluster.
