I got asked about getting Static Link Aggregation working on the default Management Network on vSwitch0, which reminded me of this frustrating incident. It’s one of those quirks that you have to swallow as a quirk and make sure to remember. Link aggregation on vSwitch0 need special attention.
One of the early tasks that occurs during a deployment is to make sure that the environment has resilience in it’s configuration, especially the fundamental network connections (VM Network, Management Network, vMotion, Storage). ESXi hosts come initially deployed with VM Network and Management Network set up on vSwitch0. If you’re working quickly and set up vSwitch0’s Link Aggregation (NIC Teaming tab), expecting it to flow through to the pre-configured networks, you’ll be let down.
Make sure you go into the VM Network and Management Networks and make sure on the NIC Teaming tab that the Policy Exceptions and Failover Order are all unchecked (unless you’re know exactly what you’re doing).
