A more even distribution of the load compared to Route Based on Originating Virtual Port and Route Based on Source MAC Hash, as the virtual switch calculates the uplink for every packet. A potentially higher throughput for virtual machines that communicate with multiple IP addresses. Disadvantages. You can work out from the switch what the hash will do with your traffic - which path the flow's will take by doing: show etherchannel load-balance hash-result interface PoX ip x.x.x.x y.y.y.y. This command can almost be your calculator (not so much online though) or . Oct 18,  · And my point was not that IP hash would work better in % of cases, it's that if you're in a situation where IP hash does work better for you, you would be able to take advantage of that within the % period of uptime vs that slight chance of failure period. But again, it's a subjective decision.
