Hi! > while replacing a switch I ran into a problem with using 802.1q VLANs > (vlan(4)) on a em(4) card - that is, I could not get the card to work > with VLANs. Have you tried fiddeling with the flags ? options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO> examples: ifconfig em0 -rxcsum -txcsum -wol ifconfig em0 -vlanmtu -vlanhwtag I have a 10.3-i386 box with 82574L and VLANs on that interface, works fine (but I'm not using it for production, only as a test box). Can you show sysctl -a | grep dev.em | grep desc I have: dev.em.5.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.1.0 dev.em.4.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.1.0 dev.em.3.%desc: Intel(R) PRO/1000 Network Connection 7.6.1-k dev.em.2.%desc: Intel(R) PRO/1000 Network Connection 7.6.1-k dev.em.1.%desc: Intel(R) PRO/1000 Network Connection 7.6.1-k dev.em.0.%desc: Intel(R) PRO/1000 Network Connection 7.6.1-k -- pi@opsec.eu +49 171 3101372 4 years to go !
