Chris Wahl at Wahl Network comments:
The use of a Link Aggregation Group (LAG) with Link Aggregation Control Protocol (LACP) is rather standard with converged infrastructure northbound uplinks. This grants additional link redundancy and avoids the need for minor levels of interruption in the event of a single link failure, and when coupled with a virtual port channel (vPC) it can also provide protection against switch failure. However, I have found that the use of a LAG, often referred to as a port channel, can cause some confusion when configuring the vSphere switch side of the equation. Nearly all documentation in the wild focuses on the need to use an IP Hash teaming policy whenever a LAG is present.
