offloading DHCP static mapping in 12.3(25)?

According to the following:

...configuring static addresses via DHCP can be accomplished from a text file found on a tftp server as of IOS 12.3(11)T.

I'm running 12.3(25) on a 2621, but I don't see the form of the "origin" command described at the above link. The documentation above states that the syntax is:

origin { dhcp | aaa | ipcp | file <url> }

...yet, I only see the following options:

Router# conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router (config)# ip dhcp pool MYPOOL

Router (dhcp-config)# origin ?

aaa Subnet is from a AAA server

dhcp Subnet is from another DHCP server

ipcp Subnet is from IPCP subnet negotiation


The documentation states that this functionality was released with 12.3(11)T. Am I correct in assuming that it is not available in 12.3(25)?

Re: offloading DHCP static mapping in 12.3(25)?

I have since gotten this to work using a different IOS image.

Which raises a question: is there any information on what features/functionality can be found in any particular IOS image? Thanks for any insight shared.
