This read-write value sets the expected long-term utilization percentage for the remote end of this connection, defaulting to 100 percent if not explicitly configured. It's the far-end counterpart to bbConnPercentUtil, used in bandwidth and admission-control calculations for the remote side of an asymmetric connection. Leaving bbRemoteConnPercentUtil at its 100 percent default effectively tells the switch to plan for the remote end fully using its allocated rate, which an admin might override downward if the remote traffic pattern is known to be lighter.
