Wir haben 2x10G NICs in einer bondSchnittstelle konfiguriert und sehen zufällig:
RX errors 28751549 dropped 46541 overruns 28751549 frame 0
Auf dieser Netzwerkkarte laufen mehrere VLANs, es handelt sich also um einen Trunk-Port.
Die Netzwerkkarte ist einBroadcom Corporation NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
Ich habe die folgende RX-Ringpuffergröße. Ich bin nicht sicher, woher sie kommt.
# ethtool -g eno49
Ring parameters for eno49:
Pre-set maximums:
RX: 4078
RX Mini: 0
RX Jumbo: 0
TX: 4078
Current hardware settings:
RX: 407
RX Mini: 0
RX Jumbo: 0

Wie kann ich dieses Problem aufspüren? Es tritt auf mehreren Servern auf, nicht auf einer einzelnen Maschine. Wir haben auch nicht so viel Verkehr, um den Link zu füllen.

Versuchen Sie, die „Aktuellen Hardwareeinstellungen“ auf den maximal zulässigen Wert zu ändern.
