The trunk has traffic with three different VLAN tags (111,222,800). I have 802.1q aware switches behind my two internal interfaces and they should only get some tagged frames (ipfw use planned to get rid of unwanted VLAN traffic) : ___ fxp1 --- switch1 of VLAN 111,222,800 / / VLANs 111,222,800 ===== em0 \ \___ fxp2 --- switch2 of VLAN 111 After bridging the three interfaces (sysctl), a dump at em0 shows all tagged frames coming from the trunk but a dump at fxp1 or fxp2 show nothing (dump with "tcpdump -nle -i..."), bridge dysfunction ? Setting up VLAN interfaces for VLAN ID 111 : ifconfig vlan0 vlan 111 vlandev em0 ifconfig vlan1 vlan 111 vlandev fxp1 ifconfig vlan2 vlan 111 vlandev fxp2 and bridging them (vlanX) together doesn't change anything. What have I missed ? -- bug sleepless To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
