Thanks for the fast reply! What would I do if I need about 10 VLANs on my 4 port interface?
The router doesn't shout at me if I configure one of the ports of the 4ESW as a trunk. Should I do that and then create interface Vlan1, Vlan2, ...? Is this a "good" solution, considering performance etc? Is there a limit for the number of VLANs (HWIC-4ESW)?
