Subscription Asset Manager - Local repository yum

Hi,

On RHEL Server 6.3 Vmware ESX.

We use Subscription Asset Manager.
We want to create a local yum repo on this machine (SAM)
We do not want our client machines connect directly to the Internet to download the update.

How can we set up a local repository yum on Subscription Asset Manager ?

How configured Subscription manager client to use a local subscription service ?

Doc :
'That means that the local Subscription Manager client needs to be configured to use the local subscription service and then the content proxy, rather than using the default Red Hat Network (hosted) configuration. '

thank you
