Create a group if you want agents to inherit specific properties from the group. Discovery agents can inherit properties from a Discovery agent group while STS agents can inherit properties from a STS agent group.
The console creates the agent group and displays the agent page again with a link to the group.
To do additional configuration of the group, click this link to display the Edit agent group page.
The attributes you can set to configure a group are the same as they are for an individual agent except that the Group, Password, and Password Confirm attributes are not available at the group level.
