This seems to better correspond to the intent of including 64 as a default size. Often you want to generate test traffic of the minimum frame size, and this makes that goal more attainable. Additionally this commit fixes a bug whereby the frame size was longer than the actual packet data, because the length in the UDP headers was wrong. --- src/program/packetblaster/lwaftr/README | 79 ++++++++++++--------- src/program/packetblaster/lwaftr/lib.lua | 53 ++++++++------ src/program/packetblaster/lwaftr/lwaftr.lua | 16 ++--- 3 files changed, 85 insertions(+), 63 deletions(-) diff --git a/src/program/packetblaster/lwaftr/README b/src/program/packetblaster/lwaftr/README index 3ae59a2058..4c340c98c7 100644 --- a/src/program/packetblaster/lwaftr/README +++ b/src/program/packetblaster/lwaftr/README @@ -16,54 +16,69 @@ Usage: packetblaster lwaftr [OPTIONS] --vlan VLANID VLAN tag traffic with VLANID if set - --src_mac SOURCE - Source MAC-Address + --src_mac SOURCE Source MAC-Address Default: 00:00:00:00:00:00 - --dst_mac DESTINATION - Destination MAC-Address + + --dst_mac DESTINATION Destination MAC-Address Default: 00:00:00:00:00:00 - --size SIZES - A comma separated list of numbers.
