1700 Router - creating a dot1q VLAN subinterface

This is my inward-facing, ethernet interface:

interface FastEthernet0 description LAN ip address 10.1.1.1 255.255.255.0

This is what happens when I create a sub-interface (Fa0.1) and try to give it dot1Q configuration:

Router_1700(config-subif)#encapsulation dot1q 2 ^ % Invalid input detected at '^' marker.

sh ver shows I have 12.2(29a) on this router.

What am I missing?

You're missing the fact that not all models of 1700 support dot1q encapsulation. Only the 1721, 1751, and if memory serves, 1760 can do this. 1720 & 1750 cannot. Check the fine print on the specs pages.

aah. I assumed the frame format would be entirely a software-related question - I never considered there would be a hardware dependency.
