    If you are disabling Advanced Throttling in any case by setting the value of <EnableAdvanceThrottling> false, Advanced Throttling is disabled and old basic Throttling mechanism is enabled thereafter. In such a scenario, if you want to disable the Unlimited Throttling tier of old basic Throttling configurations, you need to disable it under <TierManagement> by setting <EnableUnlimitedTier> to false.

It is also possible to specify a bandwidth per unit time instead of a number of requests. This can be done by an API Manager administrator. For information on editing the values of the existing tiers, defining new tiers and specifying a bandwidth per unit time, see adding a new subscription-level throttling tier
