No Yes Operator Messages Manual Chapter44IPB (Interprocessor Bus) Messages The messages in this chapter are sent by the interprocessor bus (IPB). Too Long Errors (Giants/Jumbo)A Too Long Error indicates that a packet is longer than 1518 octets (including FCS octets) but otherwise well formed. EffectIf more than 1000 of these errors occur in a 19.2-second interval, the operating system shuts down the bus to all processors and generates IPB operator message 101 (bus down).RecoveryNormally, no In a network that complies with the Ethernet standard, FCS or Alignment Errors indicate bit errors during a transmission or reception.

  2. Late CollisionsLate Collisions indicate that two devices have transmitted at the same time, but cabling errors (most commonly, excessive network segment length or repeaters between devices) prevent either transmitting device from
  3. Collisions are detected by the transmitting stations.The retransmission algorithm helps to ensure that the packets do not retransmit at the same time.

Receive DiscardsReceive Discards indicate that received packets could not be delivered to a high-layer protocol because of congestion or packet errors.8. The FCS is a mathematical way to ensure that all the frame's bits are correct without having the system examine each bit and compare it to the original.

CauseThe IPB interface on the specified NonStop Cyclone processor has encountered either a parity error or a reset on the control lines from the bus controller.

Neither device detects a collision because the time to propagate the signal from one end of the network to the other is longer than the time to put the entire packet have a peek at these guys Because only one device can transmit at a time, both devices must stop sending and attempt to retransmit.

The system returned: (22) Invalid argument The remote host or network may be down. Packets with Alignment Errors also generate FCS Errors.Both Alignment Errors and FCS Errors can be caused by equipment powering up or down or by interference (noise) on unshielded twisted-pair (10BASE-T) segments. Solution If these errors are seen on the network then the network administrator should be contacted to investigate the cause of the errors and a remedy provided. get redirected here The system returned: (22) Invalid argument The remote host or network may be down.

As a result, neither of the devices that cause the late collision senses the other's transmission until the entire packet is on the network.Although late collisions occur for small packets, the

Alignment Errors often result from MAC layer packet formation problems, cabling problems that cause corrupted or lost data, and packets that pass through more than two cascaded multiport transceivers.2.
