Hi,
I'm using the packet generator to create packets and send them to a specific
interface. My stream looks like that:
packet-generator new {
name s0
limit 1
size 115-115
node GigabitEthernetb/0/0
data {
0x0800: 00d7.8f3e.8b6b -> 1402.ec41.4540
hex
0x4500004c28ad40007c06f2415b5a8044ac175c07c4c40016f44a62d80f22f5a0501800fc681f0000af147bb332ace20645691b80367dc77291bd2fe8da9914fcd1736a6c9ec2a90070c8fe12
}
}
However, the packet originated by the packet generator contains only zeros.
This is the trace for the packet:
vpp# show tr
------------------- Start of thread 0 vpp_main -------------------
Packet 1
00:48:45:201784: pg-input
stream s3, 90 bytes
current data 0, length 90, free-list 5, trace 0x0
0x0000: 00:00:00:00:00:00 -> 00:00:00:00:00:00
00:48:45:201809: GigabitEthernetb/0/0-output
local0
0x0000: 00:00:00:00:00:00 -> 00:00:00:00:00:00
00:48:45:201812: GigabitEthernetb/0/0-tx
GigabitEthernetb/0/0 tx queue 0
buffer 0x34599: current data 0, length 90, free-list
I also verified it with tcpdump on the connected peer and the packets contains
only zeroes.
If I change the node in the stream from the output node of an interface to be
ethernet-input node, everything seems to work fine.
I'm currently using vpp 17.01.
Did someone encountered similar behavior, or alternatively managed to send
packets using the packet generator to a specific interface (without going
through the l2/l3 routing decisions)?
Thanks!
