Hi,

I am looking for uP with with two ethernet ports (MACs). I would prefer ARM
base solution, but if there is anything else it might be also interesting.

You haven't said anything about size or application.  The AVR32 AP
processors have two network ports, but you'll need external memory.

An alternative to using two MACs could be to use a microcontroller with
a single MAC and a managed switch chip set up with different VLANs on
each port.

Interesting :-)
I understand that a managed switch with VLANs allows you to run these
different LANs on the same hardware, making the individual VLAN
assignments configurable.

Can you pls provide with a link or document that talks in detail about
this alternate mechanism of using single MAC ?
