And the 2620 definately does support VLAN tagging with the proper IOS
image licensed & loaded. I believe you need at least IP+ to do it. I'd
assume that the 3661 and 7200-FE-I/O would do it with at least the
proper IOS image loaded.
I think the 1720 doesn't do it because the 1720 series platform
usually has a much reduced feature set, and its IP+ image basicly
brings it back up to the level of basic IP in the rest of the platforms.
