Process Description
Convert trace files.
It is also possible to convert trace files that have
been captured without the
align64
option. This
can be done with the command:
dagconvert -v -i in.erf -o out.erf -A8
If uncertain that a trace file is 64-bit aligned for
transmission with
dagflood
, the file can be
tested with
dagbits
:
dagbits -vvc align64 -f tracefile.erf
If a captured trace file is not available, the
daggen
program is capable of generating trace
files containing simple traffic patterns. This
allows the DAG card to be used as a test traffic
generator.
Capture received
traffic while
transmitting.
It is possible to capture received traffic while
transmitting. Capture programs such as
dagsnap
,
dagconvert
, and
dagbits
can be
used while dagflood is sending packets. Use of
133MHz PCI-X is recommended to ensure
adequate bandwidth is available for
simultaneous receive and transmit operation.
