ubr7200 (7246) and VLAN Trunks

Has anyone successfully setup a VLAN subinterface on a ubr7200? All of the documents I have seen on TAC state I should use the encapsulation command but it is not available. I want to do something like:

interface gig 2/0.500

encapsulation dot1q 500

ip address x.x.x.x y.y.y.y

uBR7246VXR (NPE300) 13.3(17a)BC

1 FastEthernet/IEEE 802.3 interface(s)

1 Gigabit Ethernet/IEEE 802.3 interface(s)

1 ATM network interface(s)

1 Cable Modem network interface(s)

I believe the support for 802.1Q is IP Plus feature sets across all L3 platforms. What IOS feature set is the uBR running?

It is "DOCSIS 2-WAY 3DES LAWFUL INTERCEPT". I have only setup VLAN routing on MSFCs (Cat 6K) and RSMs (Cat 5K) before so I would not have noticed if 802.1Q was restricted to a particular feature set.

Re: ubr7200 (7246) and VLAN Trunks

I thought I had tried an IP+ feature this weekend out of desperation. I downloaded it but I guess I didn't copy it to flash. Is there a decent chart that shows the differences? I kind of got burned on something similiar when I ordered a 3750. I was assured the base install was sufficient for my needs. A few weeks later and before the 3750 came in (I had the delivery pushed for budget reasons), I was discussing adding some additional equipment, the VAR sales rep suddenly realized I needed the enterprise version. My CFO was not happy about the unexpected expenditure. At least this router isn't in my cost center and instead belongs to an engineering department.
