Need help configuring static nat on 2600 IOS 11.3(2)XA1

I'm attempting to setup static NAT to help ease the process of consolidating addresses. I have followed the guidelines to the word as presented in the Cisco documentation series for my IOS, but it seems the commands simply do not exist.

I am referring to this document:

I am executing the commands in Global config mode:

pericles(config)#ip nat inside source ?

list Specify access list describing local addresses

pericles(config)#ip nat inside source static ?

% Unrecognized command

Is there something I am missing? I have tried adding the inside and outside designations to the interfaces first, then trying to specify the static translations, but the command still does not appear. Seems like all I can do is configure dynamic translations, which is not what I am trying to do.

Here's what I get when I query the ip nat command:

pericles(config)#ip nat ?

inside Inside address translation

translation NAT translation entry configuration

seems odd that there aren't more commands, like pool or outside.

What am I missing here? Any help would be very appreciated.
