Je n'ai pas la moindre id=E9e de ce que ce truc peut =EAtre... Les MAC addr=
ess (pour autant que ces valeurs soient bien des MAC) ne ressemble a rien d=
e connu su le r=E9seau et tout fonctionne normalement.
Dans mes hypoth=E8ses il y a: 1, matos defect, et 2, bug dans le soft de c=
apture, avec une pr=E9f=E9rence pour le 2...

Ca ne doit pas =EAtre bien grave, mais si vous avez une id=E9e de ce que ce=
tte trame repr=E9sente, je prend; Au besoin je peux refaire une capture au =
format pcap...

Merci,
