LAN Driver Statistics for Novell Drivers
This integration note describes the statistics to diagnose network problems via the Novell
MONITOR modules.
The statistics supplement the diagnostic information that would
normally be obtained with a protocol analyzer or network monitor and gives an estimate
of network and controller activity.
