Ethernet Controller Help

Detailed information about the selected ethernet controller is displayed. This page can be used to clear the controller status.
The progress bar is displayed when there are a lot of numbers of network interfaces in the partition.


PCI Device Information

Item Description
Unit Unit identification name
Status Hardware status of the ethernet controller:
- OK: Operating normally
- Error: Serious problem such as a hardware failure has occurred.
- Warning: A problem will possibly occur.
- Unknown: PCI device status information is not available.
A check box is provided and can be used to clear the status.
Device Name Name that combines the vendor name and device name
Device Class(hex) PCI Device class ID
Seg/Bus/Dev/Func Segment number, bus number, device number, and function number
Vendor ID(hex) PCI Vendor ID
Device ID(hex) PCI Device ID
PCI Device Version(hex) Version number of the PCI device
MAC Address Physical address
Speed Current network speed

MAC Statistics

[Transmit Statistics]
Item Description
Total Packets The number of packets transferred to IP for transmission by transport layer protocols. It does not include packets that were simply forwarded.
Total Bytes The number of bytes that have been transmitted by the selected interface.
Deferred Xmits The number of packets for which the initial transmission attempt had to be delayed because the line was busy. Deferred Xmits occur in conjunction with network congestion.
Single Collisions The number of packets that could be successfully transmitted after exactly one collision. Single Collisions are an indication of network congestion.
Multiple Collisions The number of packets that could be successfully transmitted after several collisions. Packets that have already been recorded under Single Collisions are not included here. Multiple Collisions are an indication of network congestion.
Excessive Collisions The number of packets for which a transmission failure occurred because the maximum number of permissible collisions was exceeded. Excessive Collisions are caused by extremely severe network congestion.
Carrier Sense Errors The number of cases in which the carrier sense condition was violated. The carrier sense condition is violated when a particular station transmits and then does not detect its own signal on the line. Carrier Sense Errors can be caused either by cabling defects or by a defect in the network module.
Late Collision Errors The number of cases for which a collision was not detected until more than 512 bits had already been transmitted. Late Collision Errors are indications that the transmission route is too long, thus producing overly long signal propagation times.
SQE Test Errors The number of times that an SQE Test Error was generated.
MAC Xmit Errors The number of packets that could not be successfully transmitted due to an internal error on the MAC layer. A packet is included here only if it has not already been recorded under Late Collision Errors, Excessive Collisions or Carrier Sense Errors. The actual errors counted in this field depend on the implementation.

[Receive Statistics]
Item Description
Total Packets The total number of all IP datagrams that were received by the selected interface from all other stations, including error datagrams.
Total Bytes The number of bytes received by the selected interface.
FCS Errors The number of packets that comprise an integral number of bytes, but for which the FCS test detected an error. FCS Errors are the result of poor transmission quality.
Alignment Errors The number of packets which were received by the selected interface, but whose lengths cannot be correct because they do not comprise an integral number of bytes. Alignment Errors are caused by poor transmission quality.
Frame Too Long The number of packets which were received by the selected interface, but whose lengths exceed the maximum permissible packet length(1518 bytes).
MAC Receive Errors The number of packets that could not be successfully received due to an internal error on the MAC layer. The actual errors that are counted in this field depend on the implementation.
