RE: em driver + VLAN's

FreeBSD 4.9 - char em_driver_version[] = "1.7.16";

I've tried multiple bridge configurations - from bridging just em0,em1 to
bridging two vlan's attached to each card. Unfortunately I don't have access
to the box at the moment - if its still necessary I will fetch the
information tomorrow (ifconfig etc)

To sum up its something like the following
net.inet.ether.bridge_config=em0,em1
net.inet.ether.bridge=1

Or vlan0,vlan1 with:
ifconfig vlan0 create
ifconfig vlan1 create
ifconfig vlan0 vlan 100 vlandev em0
ifconfig vlan1 vlan 100 vlandev em1


If I change to using fxp it immediately works..

Thanks for the help
Dave

This probably can. What FreeBSD version are you using? Can you please show
ifconfig output and bridge configuration?
