Hi Chinmaya,
Given that you’re getting packets in the listener’s rx fifo, I suspect the
request to make it a connected listener didn’t work. We’ve had a number of
changes in vcl/session layer so hard to say what exactly might be affecting
your app.
Just did an iperf udp test on master and ev
Hi,
We are using connected socket (setting VPPCOM_ATTR_SET_CONNECTED) but still
facing this issue. Has something changed between VPP v21.06 and the new release
for the connected udp socket?
Thanks and Regards,

Hi Chinmaya,
Given that data is written to the listener’s fifo, I’ll guess vpp thinks it’s

We re-compiled VPP 22.10 by cherry picking the below commits:-
udp: fix tx handling of non-connected sessions :
15952b261f92959ca14cf6679efc318c12e90de6
udp: support for disabling tx csum : f8ee39ff715ec713045af69da465ba4da8248212
udp: explicit udp output node This allows for custom next nod
Hi Chinmaya,
Are you by chance using 23.02rc0, as opposed to 22.10, in combination with
non-connected udp listeners? If yes, could you try this fix [1] or vpp latest
to check if the issue still persists?

Florin

Hi,
We are testing VCL in VPP 22.10 and facing the issue that VCL is not able to
accept UDP connections and we are seeing rx full in "show session verbose"
command:--
vpp# show session verbose
Connection State Rx-f
