this is apparently an IOS limitation. A pal of mine was telling me that
commencing with IOS 12.2 that trunking and subinterfaces are permitted on
regular old ethernet 10baseT interfaces. This is certainly not true on 12.1
well, clarification - subinterfaces are permitted for IPX routing, but not
for IP routing. IP requires ISL or 802.1q trunking. this apparently changes
with IOS 12.2
help?

Jimmy,
I don't see why it would not work on an Ethernet interface when it does on
FastEthernet, but I don't have one to test on right now. Give it a shot, it
should work.
