Cisco 3XGigE card question(3GE-GBIC-SC=)

I have a 3XGig E card in a Cisco 12000 series router.
I can create sub-interfaces, but when I try to set rate-limits, the commands are not available. How ever I can create sub-interfaces on a 1XGig E card, and can set rate-limits. Has anyone else run into this problem?

Example:

interface GigabitEthernet1/0.800
description ** Connection to Matrix **
encapsulation dot1Q 800
ip address X.X.X.X 255.255.255.128
no ip redirects
no ip directed-broadcast
rate-limit input 8192000 4096000 4096000 conform-action transmit exceed-action drop

interface GigabitEthernet2/1.700
description ** Connection to Poplar LAN **
encapsulation dot1Q 700
ip address X.X.X.X 255.255.255.240
no ip directed-broadcast
no cdp enable
(config)#interface GigabitEthernet2/1.700
% Unrecognized command
(config-subif)#rate?
