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.
