I regularly configure Vlans on Cisco router by using SUB interfaces like FastEthernet 1.200 .
Now i have to configure a vlan on a 851 with Advsecurity software. This command does not seem to be available? Is this a software restriction, or is it a different configuration method? I can see a command called VLAN, and i made a VLAN30 interface, but it seems to be UP/DOWN. Obviously i need to do some sort of layer 2 configuration also to get this interface up and running.
My question; how do i configure VLAN on this router, or is it not possible? config available upon request.
