amount of under-runs. The higher this number, the more time the adapter is waiting before starting to
transmit data onto the wire. Poor bus performance, large amounts of traffic or a large number of
devices on the same bus can cause this to rise. If this number is always above 170, you may want to
consider loading the driver with the TxThreshold parameter set to a higher value, such as 200.
• RstartCnt
Re-Start Count, also known as RSC, is a support counter to see how often the restart effort occurs.
Under some high traffic, or high utilization conditions, the receiving unit does not start normally and
needs a restart. RSC has no impact on the end user. It is intended for software development use
only. It is normal for this to be non-zero.
• REC
Under some busy conditions, the receiving unit stalls and needs to be restarted. This counter tracks
the number of times it needs to be restarted. RSC is a subset of REC. Most REC events restart
normally, but the few that do not are REC events. This counter is intended for software development
use only and may be disregarded by the end user. It is normal for this to be non-zero.
• Checksum Good
This counter indicates the number of received packets that the hardware has verified, the checksum,
and if the checksum is valid.
• Checksum Bad
This counter indicates the number of received packets that the hardware has verified, the checksum,
and if the checksum is valid.
• Stalled Ints SW Resets
This counter indicates the number of times the driver issued a complete reset (to the driver and to the
adapter) as a result of a stalled interrupt situation. A stalled interrupt situation is detected by the
driver if there are no interrupts for a long time, and a SW interrupt issued by the driver fails to
arrive.
• Carrier Loss PHY Resets
This counter indicates the number of times the driver reset the PHY as a result of carrier sense loss.
N1000 and N1000e custom counters
• Duplex Mode (1=Half, 2=Full)
This counter indicates the current link duplex configuration. A value of 1 indicates the adapter is
configured to half-duplex mode. A 2 indicates full-duplex mode configuration. This counter exists in
v1.12 or higher of the NetWare server driver.
• Line Speed (Mbps)
This counter displays the current line speed in Mbps.
• Configured Duplex Mode (0=Auto, 1=Half, 2=Full)
• Configured Speed (Mbps; 0=Auto)
• PCI Mode (0=PCI, 1=PCI-x, 2=PCI-Express)
• Bus Clock Rate (Mhz) (0=Unavailable)
• Link Status (0=Up, 1=Down)
This counter describes the current link status of the adapter. A value of 0 indicates the link is up and
a value of 1 indicates that the link is down. This counter exists in v1.12 or higher of the NetWare
server driver.
