This read-create TruthValue, when set to TRUE, causes the Ethernet Flow's bandwidth to be automatically adjusted as PWE3 SATOPs are provisioned, based on the TDM entities of the associated SATOPs. It is applicable only to flows on the PWE3 Ethernet Backplane Port; flows on other ports always report FALSE and cannot be configured. For example, an administrator enables auto bandwidth config on a PWE3 backplane flow so its bandwidth automatically grows as more TDM circuits are provisioned over the pseudowire.
