Why don't ng_fec (Cisco FastEtherChannel netgraph module) and
`pseudo-device vlan' (802.1q trunking) work together?
I can get each of them to work independently.
If it makes any difference I cvsup'd to (and built/installed) RELENG_4
this morning
The following is my goal :
Cisco Switch FreeBSD
/Port 4/1--------------fxp0\ /vlan0
dot1q Trunk - EtherChannel< >--fec0---<
\Port 4/2--------------fxp1/ \vlan1
\vlan2
\vlanN
I set this up as follows :
kldload ng_fec
/usr/sbin/ngctl mkpeer fec dummy fec
/usr/sbin/ngctl msg fec0: add_iface '"fxp0"'
/usr/sbin/ngctl msg fec0: add_iface '"fxp1"'
ifconfig fxp0 up
ifconfig fxp1 up
ifconfig fec0 up
ifconfig vlan0 inet 10.107.1.83 netmask 255.255.255.0 vlan 1 vlandev fec0 up
If I `tcpdump' fxp0 I see dot1q tagged packets
If I `tcpdump' fxp1 I see dot1q tagged packets
If I `tcpdump' fec0 I see dot1q tagged packets
If I `tcpdump' vlan0 I see nothing...
I am not skilled enough to diagnose the kernel internals to discern why
this doesn't work. I am willing to test any patches that may turn up.
Thanks
