Can't capture pkts with an ethertype less than 0x05DC

[NicoN]

Hello, I am using an intel I350 card (igb driver) to monitor a specific network. Frames on this network have an ethertype less than 0x05DC. Tcpdump does not capture any frames on any port of the intel card, but if I use another card it works. I tried to modify all the parameters with ethtool, without success. Can you help me?

Bonjour, le port est connecté sur un réseau ethernet avec un ethertype commençant par 0x01... ce qui normalement  doit correspondre a la taille de la trame, mais ce n'est pas le cas, l'ethertype correspond a un type de trafic (non ip).  Est il possible d'utiliser une carte intel pour un reseau autre qu'IP ? avec des ethertypes commencant par 0x01...?

Bonjour Sazirah, le problème n'est pas résolu et nous n'avons pas eu le temps d'investiguer plus. Pour le moment nous prévoyons d'utiliser une autre carte.

Cordialement
