I don't know what platform you tried it on, but I've only tested it on  
software-based routers: 7301 (running 12.4T), 7204 VXR (12.3T).  
Therefore I'm not sure if it's the hardware platform that doesn't  
support it (I wouldn't be suprised if it doesn't work on GSRs or  
specific line cards) or if you need a different IOS train.

I'd need to look it up in IOS documentation...
