Hi there!
I'm faced with unexpected behavior when try to send LACP packet to port under testpmd control. Here is what I did :
- Bind port to igb_uio driver:sudo usertools/dpdk-devbind.py --unbind 0000:8b:00.7sudo usertools/dpdk-devbind.py --bind=igb_uio 0000:8b:00.7
- Run testpmd:
sudo ./dpdk-testpmd --log-level=debug -l 2,3 -- -i - Start forwarding:
testpmd> start tx_firs - Send from another server LACP packet to port under testpmd control
- Show xstats and it's all good for now:
testpmd> show port xstats 0rx_good_packets: 4rx_unknown_protocol_packets: 0 - reset port 0testpmd> stoptestpmd> port stop 0testpmd> port reset 0testpmd> port start all
testpmd> start tx_firs - Send from another server LACP packet to port under testpmd control
- Show xstats and see that `rx_unknown_protocol_packets` encountered:
rx_good_packets: 0rx_unknown_protocol_packets: 4
Configuration: E810 NIC, firmware-version: 3.10, DPDK version: 21.11.0.
I don't know if this behavior is normal, but I would like the LACP traffic not to be dropped by the card. Thanks!
