DL380G3 and 802.1Q trunks?

[Jonas Back_1]

There are several posts in the forum regarding 802.1Q trunks and NICs but I still can't get it to work. What am I missing?

What we simply want to do is to connect our Windows 2000 Server installed on a DL380G3 (with NC7781 NIC) to a port on our Cisco 2950 switch, which only support 802.1q. The port is configured with the command:
"switchport mode trunk"
No VLANs are cleared from the trunk.

What we want to do is have the NIC to be configured to be on both:
VLAN10 (192.168.10.0/24) and
VLAN20 (192.168.20.0/24)

What else do you have to do except configuring the IP-adresses for the NIC? Can't find any settings ni the driver. We have also tried teaming the NICs and connecting the NICs to seperate switches and configuring them as trunks.

Not a strong network guy, so I'm not sure if this has anything to do with this problem, but I believe the NC7781 only has the following compatibility: IEEE 802.3, 802.3u, 802.3ad

Could be but there IS a "802.1Q approved" network drive - but only for Linux so far.

Have you configured this setup, but with another network card, yourself?
