Hello
my company is thinking about switching from fastnetmon community to fastnetmon advanced. Since there is no more netmap support in the current advanced version I am trying to set up XDP (native mode).
OS: Debian 11
Here's my configuration:
https://pastebin.com/xGgUE55SThe config as it is in the pastebin works fine and shows traffic.
However, as soon as I type "set main force_native_mode_xdp true" & commit, all the counters go to zero and stay at zero.
Here's the logs:
https://pastebin.com/5uFyuN0CNote that I am using Intel XL710 as requested per the documentation:
# lspci | grep 710
04:00.0 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
This is the error message that's in the logs after activating native mode:
2022-05-23 15:07:05,771 [INFO] Interface ens161 has enabled flag 'promisc' already
2022-05-23 15:07:05,771 [INFO] Will use native XDP mode
2022-05-23 15:07:05,771 [ERROR] Cannot assign BPF microcode to interface ens161 error code: -17 error: File exists
Has anyone succeeded in running fastnetmon advanced in xdp native mode?
