Setting up VLAN on T420

Hi,

My PE T420 has a single Ethernet controller (BroadCom BCM5720) with 2 ports. I need to setup VLANs to isolate one port from the other one.

I have some questions related to this need:

- Can I create such an isolation on a single controller (even if it has 2 ports), or do I need 2 controllers?

- In iDrac, those 2 Ethernet ports are marked as "Partition - Not Capable", what does this mean?

Thanks.
