And also i tried ng_bpf + ng_eiface conjuction, but ng_bpf doesnt match "vlan" filter.
With the script below, ng_bpf always calls ifNotMatch hook. When the pattern is "ip", ng_bpf matches frames have both vlan and ip headers. I think ng_bpf doesnt process ethernet header. Is there a way to process ethernet header with ng_bpf ? Script is below: #!/bin/sh ETHER_IF=em0 PATTERN="vlan" BPFPROG=$( tcpdump -s 8192 -ddd ${PATTERN} | \ ( read len ; \ echo -n "bpf_prog_len=$len " ; \ echo -n "bpf_prog=[" ; \ while read code jt jf k ; do \ echo -n " { code=$code jt=$jt jf=$jf k=$k }" ; \ done ; \ echo " ]" ) ) echo $BPFPROG # Shutdown nodes if exists ngctl shutdown ${ETHER_IF}: ngctl shutdown vlan_filter: ngctl shutdown tag0: ngctl shutdown untag0: ngctl -f- <<EOF mkpeer ${ETHER_IF}: bpf lower filter_in name ${ETHER_IF}:lower vlan_filter mkpeer vlan_filter: eiface taggedPacket ether mkpeer vlan_filter: eiface untaggedPacket ether name vlan_filter:taggedPacket tag0 name vlan_filter:untaggedPacket untag0 msg vlan_filter: setprogram { thisHook="filter_in" ifMatch="taggedPacket" ifNotMatch="untaggedPacket" $BPFPROG } EOF ifconfig ngeth0 up ifconfig ngeth1 up On Fri, May 2, 2014 at 11:53 PM, Özkan KIRIK <ozkan.ki...@gmail.com> wrote: > Hi, > > Assume that default vlan untagged and VLAN 10, 20, 30, 40 tagged on switch > connected to em0 interface. > > i am trying to bridge only untagged frames on em0 with em1. > > Does if_vlan handle untagged frames? > > # ifconfig em0.0 create > ifconfig: SIOCIFCREATE2: Invalid argument > > Any ideas? > > Best regards, > _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
