I have a cisco 1721 that doesn't let me set the encapsulation for
fastethernet subinterfaces. I tried several IOS images using Feature
Navigator, but no results.

I took the image running on another 1721, loaded it into the one with
the problem, but it still didn't work.

=== cut here ===
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int f0.1

Router(config-subif)#enc dot1q 1
% Invalid input detected at '^' marker.

=== and here ===

The only difference between the 2 routers is in the output of show ver:

The one that works: MPC860P processor: part number 5, mask 2
The one that doesn't work: MPC860P processor: part number 0, mask 32

I searched on google, but i didn't find anything. I asked the output
interpreter, but still nothing :)

Any ideeas?
