Ah, I see I was wrong.  I also just checked one of our 2600s running 12.2
and it had it.  When I checked earlier I was looking at a 2500 running
11.2(18).  When I looked for that at home I must have looked on the router
that was still running 11.2.  I'm sure if I'd look at the 12.1 routers I
would have seen it.
Thanks,
John
