This TruthValue setting controls whether the switch's link-aggregation load-balancing hash treats IP-over-MPLS traffic the same as ordinary IP traffic when spreading frames across a LAG's member links, and the description notes it can't be enabled if a related balancing-layer setting equals 2. An administrator would enable this on a device carrying MPLS-encapsulated IP traffic across an aggregated link so that load balancing looks past the MPLS labels to the underlying IP addressing for a more even traffic spread, keeping in mind it affects all services on the device, not just this one link. With the default value of false, the switch treats MPLS-tagged packets as non-IP traffic for hashing purposes unless this is explicitly turned on.
