Once system initialization is complete, packet rejection should be a rare event. The only non-error rejection after initialization would be the arrival of a broadcast message which is intended to travel to the end of the chain and then be dropped by the end-of-chain device. Prior to the completion of system initialization, other devices may have not completed link initialization ( Link Initialization bit is clear). If they have not been programmed to hold incoming packets pending completion of initialization ( Drop on Uninitialized Link bit is set), they will behave as an end-of-chain device and reject packets temporarily. Actions taken when a packet is rejected by an end-of-chain device, or by an interior device which has not completed initialization and is behaving temporarily as one, depends on the type of packet.
