This read-write value sets the bandwidth allocated to a FlexE interface. An admin adjusts this to provision how much of the FlexE group's aggregate capacity this particular interface is allowed to use, and a reduction below the prior value triggers the module's hh3cFlexEBandwidthReduce notification. For example, reducing this from 100000 to 50000 on an interface would generate a bandwidth-reduce trap, alerting the admin that a client's allocated capacity was cut in half.
