Behavior of a Distributed Port Group

I'm not well verse in the Distributed Switch architecture.

Would like to know the default behavior of a Distributed Port Group when teaming and failover are configured as below.

Teaming and failover

Load balancing: Route based on originating virtual port

Network failure detection: Link status only

Notify switches: Yes

Failback:

Active uplinks: Uplink 1, Uplink 2

Standby uplinks:

Unused uplinks:

A distributed port group is configured under a distributed Switch.

It has a two Uplink. Each Uplink has one vmnic card.

What is the behaviour during normal operations? Does the traffics flow using both vmnic?

In the event of one uplink is down will a VM lost its network connection?

If you know an article that explain this behavior please share.

Thank you

when teaming and failover are not configured.

teaming and failover are always configured, it just may be the settings have been altered from the defaults. If that's so in your case, please explain how it is configured.

By default, there is an active and a standby uplink configured. Should the active fail, the standby takes over and all port groups configured for that will use it as their uplink. If multiple uplinks are listed as active, VMs and their vnics will be placed (not necessarily balanced) across them. The only time a VM would lose connectivity is if you only had a single active uplink for a given port group with no standby and any other uplinks in the unused category.
