No, you don't have to configure LAG.
If LAG is configured, then the portgroup's load balancing should be configured to Route based on IP hash, that's why I asked.
You should not use a gateway for Channel Network which means, two channel adapters must be in a same subnet.
ESXi servers can be on two different subnets but for Channel Network, they must be in a same subnet!
For example:
- Primary Channel Adapter=> 130.216.1.10
- Secondary Channel Adapter => 130.216.1.11
As per the screenshot attached, no gateway no DNS!
