[c-nsp] Can't configure IP SLA

What do you get from 'show ip sla app' or 'show rtr app'?
You might need the older syntax on that release.
If you only see 'show ip sla responder' then the IPServices feature-set
that you are using only has the responder functionality, not the entire
IP SLA code base.  You'd need to move up to something higher...  IP

Hi guys,

I've got a new Cisco 3550, and i'm trying to play around with the IP sla

(IP SLAs - ICMP Echo Operation 
I'm pretty sure the IOS is capable of this because i went to Cisco 
feature navigator (http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
<http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp> ) and 
it confirms the IOS image i'm using on this device model should support 
ip sla.

The IOS i'm using is Cisco IOS Software, C3550 Software 
(C3550-IPSERVICESK9-M), Version 12.2(25)SEE1, RELEASE SOFTWARE (fc1)

However, when i go to config mode, i get this:

Switch(config)#ip sla ?
% Unrecognized command

Is there something i need to enable?
