TReX isssues with Intel NIC ixgbe

[riasudeen]

Hi,

I am new to TReX, TReX running in RHEL 7.2 and defined 2 No's of 10Gig Interface ports in trex_cfg.yaml

Interface Details:

Intel 82599ES 10-Gigabit SFI/SFP+

driver: ixgbe and version 5.3.5 (Ensured its latest NIC drivers)

Normally, I am able to see above interfaces when run "ifconfig" or "nmcli conn show"

This interfaces disappears from ifconfig  after i do trex test, Also ethtool not able to find the NIC

# sudo ./t-rex-64 --cfg /etc/trex_enp129s0f_cfg.yaml -f cap2/dns.yaml -c 4 -m 1 -d 10 -l 1000

Starting TRex v2.34 please wait ...

set driver name net_ixgbe

driver capability : TCP_UDP_OFFLOAD TSO

set driver name net_ixgbe driver capability : TCP_UDP_OFFLOAD TSO

<Omitted test output> ...............................................

# ethtool enp129s0f0

Settings for enp129s0f0:

Cannot get device settings: No such device

Cannot get wake-on-lan settings: No such device

Cannot get message level: No such device

Cannot get link status: No such device

No data available

Any help would be highly appriciated

Thanks,

Gani

Thanks @Yaroslav Brustinov

I see ports Returning to Linux after entering the command you mentioned above.

Hi,

Upon TRex start, it removes the interfaces from Linux native driver and binds to it's own driver (for increased speed).

To return the interfaces to Linux:

1. Ensure TRex is not running
2. Run following command: (little L as argument)
   sudo ./dpdk_setup_ports.py -l

Thanks,

Yaroslav.
