[netperf-talk] question about DLPI transfer performance

[william]

hi, folks :
When I use netperf to measure DLPI's transfer performance, I got a error
below.
And I didn't have this file -- /dev/dlpi.
What can I do?
My OS is SOLARIS.

/usr/local/bin # ./netperf -H 11.0.1.105 -t DLCO_STREAM
DLPI CO STREAM TEST
Recv Send Send
Window Window Message Elapsed
Size Size Size Time Throughput
frames frames bytes secs. 10^6bits/sec

netperf: dl_open: open of /dev/dlpi failed, errno = 2
netperf: send_dlpi_co_stream: dlpi stream data descriptor: No such file
or directory



thanks.
