How to detach and attach the network interface from VM1 to VM2 during failover?

Question

Hi team,

We have 2 F5 load balancer VM's configured in our environment. With the current situation when we initiate the manual Failover, the switching of N/W interface is taking about 7-12 minutes to complete the DR activity. However, we would like to perform auto switching of these network interface from VM1 to VM2. How can we perform this.

What is the average time taken to detach and attach the network interface from 1 VM to another?

Please suggest.

Hi @Geeaz

I will suggest you other way, no need to detach and attach the network interface. just change IP address VM1 to VM2

1. First shutdown VM1
2. Change dummy IP address on the VM1
3. Shutdown VM2
4. Update VM1 IP address on VM2

No... I am aware on this. However, I need dettach and attach the Network interface with the IP configurations using powershell.

For example.
On a VM, we have 3 NIC's and one of the NIC have more IP configurations setup. We want to move this NIC and its IP configs to the VM2.
