No "encapsulation" command on IOS 12.2(12a) ??

Kind of OT for NANOG, you should go to cisco-nsp for these kinds of
questions.

However, to answer your question anyway you need an IP plus version of IOS
to get 802.1q/ISL subifs on a 36xx router.  That's only plain IP (c3620-i
vs. c3620-is)

Show Version:

Cisco Internetwork Operating System Software
IOS (tm) 3600 Software (C3620-I-M), Version 12.2(12a), RELEASE SOFTWARE
(fc1)

flash image:
System image file is "flash:c3620-i-mz.122-12a.bin"

I'm trying to configure a FastEthernet sub interface for 802.1q VLANs, but
theres no encapsulation command. I've googled it up for about 2 hours and
have come up with nothing... the following command sequence is documented
dozens of times:

As shown on:

t/120t1/8021q.htm#wp3944
interface fastethernet slot/port.subinterface-number encapsulation dot1q
vlanid

Any help would be appreciated.
