Replication cmdlets are missing in Powershell 3.0

Hi,

I am been using powershll 2.0 for a while and I have updated it to powershell 3.0.The following is my setup

Domain Controller:Windows server 2008, FFL and DFL is server 2008

I am using Windows 7 sp1 ultimate as management workstation in which I have installed RSAT and powershell 3.0.

The issue is I couldn't see the new cmdlets introduced in 3.0 to manage sites.I checked the version and it says 3.0.

Am I missing requirement?.

Please let me know if any details required.

Thanks

Ragavan
