mscFrUniSigUpdateBCI 1.3.6.1.4.1.562.36.2.1.71.6.12.1.19

This attribute specifies whether internal Backward Congestion Indication (BCI) bits will report congestion external to the Passport network, as communicated through incoming BECN bits. If updateBCI is set to on, then BCI bits for incoming frames will be set if the BECN on the frame is set. If updateBCI is set to off, then incoming BECN bits has no effect. Setting updateBCI on for a DLCI means that the remote end of the DLCI, which is specified by the remoteDna and remoteDlci attributes of the Dc component of the Dlci, may perform Rate Adaptation using the flow of incoming BECN bits, in addition to internal Passport congestion management systems. If the rateAdaptation attribute of the remote DLCI is provisioned as eirOnly, cirProportionate, or on, then congestion from another network connected to a Passport network may trigger dynamic congestion management. If there is no rate adaptation at the other end, then the setting of updateBCI attribute here will have no effect.
