Hi community! I’ve few customers complaining about the speed/quality of the service, and everything looks good from multiple parameters I typically check (lan speed, SNR, retransmission, speed check, etc.). I’ve FQCodel so traffic prioritization is not the issue, even for simple pages (non-sensitive to real-time), whatsapp, facebook, web browser, etc.
However, when checking the logs I think I found a pattern on those customers:
send_lldp: SIOCG-IF-INDEX failed for eth1 in a row for the same day.
And I say Multiple because that log is also present on “healthy” customers too (fewer logs though), I’m not sure if that is just adding noise to my research.
So I’ve a couple of questions:
- What does
send_lldp: SIOCG-IF-INDEX failed for eth1mean?
- Do you think that may be causing an issue?
