I have a soekris net6501 running obsd 5.0 and am having problems
creating a trunk interface between it and a Netgear GSM7228PS managed
switch. The switch is configured such that ports 23 and 24 are in a LAG
group and all traffic from vlan id's 2 and 3 should leave the lag
tagged. After creating the trunk and vlans on the net6501, I'm finding
that all traffic traveling through the switch is not properly tagged
even though traffic from the net6501 is. If I remove the lag on the
switch and create the vlans on a single interface, everything works as
expected. Based on that, I thought it was a netgear issue and contacted
them. After hours of trouble shooting with no luck, I just happened to
take the same 5.0 image and run it on a soekris net5501. This worked
without any problems when using a trunk so I'm pretty confident that the
switch is configured properly, but am confused about why the trunk
interface will work on a net5501 and not a net6501. The only thing I can
thing of at this point is the net6501 is using the em driver with 4x
Intel 82574IT Gigabit Ethernet ports and the net5501 is using the vr
driver with 4 VIA VT6105M 10/100 Mbit Ethernet ports, but not sure why
it would matter. Any help in identifying the problem would be
appreciated.
This is how I created the interfaces... the only difference between how
I configured the net6501 and the net5501 was that the net5501 uses the
vr driver as opposed to the em.
