NIC Teaming Policy: Route based on the originating virtual switch port ID
Choose an uplink based on the virtual port where the traffic entered the virtual switch. This is the default configuration and the one most commonly deployed.
When you see this setting, traffic from a given virtual Ethernet adapter is consistently sent to the same physical adapter unless there is a failover to another adapter in the NIC team.
Replies are received on the same physical adapter as the physical switch learns the port association.
This setting provides an even distribution of traffic if the number of virtual Ethernet adapters is greater than the number of physical adapters.
Note: If you select either srcPortID or srcMAC hash, you should not configure the physical switch ports as any type of team or bonded group.

We have NIC1 connected to Switch1 and NIC2 connected to switch2. The two switches are trunked together. Although we have Spanning Tree enabled, we had ProCurve support review our switches and they determined that STP is not blocking any ports. Using the NIC Teaming policy based on port ID, does this mean that there will be no network loop?
