Dear List, I am experiencing problems bridging two vlans on a linux box running debian. I have a single interface (eth0,Broadcom NetXtreme BCM5705M_2 with tg3 module). This interface has a trunk to a catalyst switch. I've created two virtual interface with vconfig: vconfig add eth0 608 vconfig add eth0 609 At this point all is fully functional, I am able to see traffic on those virtual interfaces and if I give them the ip stack I can use them. Then I decided two bridge the two virtual interfaces. So I created a bridge with brctl : brctl addbr br0 and I've added those virtual interfaces to the bridge : brctl addif br0 eth0.608 brctl addif br0 eth0.609 Last thing I enable all the interfaces : ifconfig br0 up ifconfig eth0.608 up ifconfig eth0.609 up The first thing I noticed is that I cannot see any traffic on br0 interface and also on the virtual interfaces. As far as I know the bridge code supports tagged packet but I am not able to see any traffic on the interfaces. Moreover the tg3 module support natively vlan traffic. This is what I see on both br0 and virtual interfaces after I add them to the bridge : 14:23:22.539413 00:0a:b7:23:61:97 > 01:00:0c:cc:cc:cd SNAP Unnumbered, ui, Flags [Command], length 50 14:23:22.540865 00:0a:b7:23:61:97 > 01:00:0c:cc:cc:cd SNAP Unnumbered, ui, Flags [Command], length 50 Any ideas ? cisco
