Hi,
Please help me to understand how VLAN filtering works with ixgbe driver.
I have the following setup
2 x Intel(R) 10 Gigabit XF SR Dual Port Server Adapter, 82598 controller
OpenSuse 11.2, 64 bit, kernel version: 2.6.31.5
ixgbe-2.0.44.14-NAPI
I have 4 ixgbe interfaces (eth1, eth2, eth3, eth4), and I would like to bridge
them.
I would like to bridge only some specified VLANs (101 and 102).
I have to cope with mass traffic, so effective VLAN filtering is very important.
I would like to use the 82598 controller's HW VLAN filtering.
I use the following script:
input_eths="eth1 eth2 eth3 eth4"
input_vlans="101 102"
echo ""
echo " Setting up input interfaces ..."
for eth in $input_eths
do
echo " $eth"
ifconfig $eth 0.0.0.0 up
for vlan in $input_vlans
do
vconfig add $eth $vlan
ifconfig $eth.$vlan up
done
done
echo ""
echo " Setting up bridge ..."
brctl addbr br0
for eth in $input_eths
do
for vlan in $input_vlans
do
brctl addif br0 $eth.$vlan
done
done
ifconfig br0 up
My question is the following:
If I use the vconfig utility to specify VLANs, does it result HW vlan filtering
in the 82598 Controller,
or VLAN filtering is expressen only in the Linux (in the ixgbe driver or in the
Linux network stack)?
Thanks,
