5.2 agent I don't believe will support what your trying to do.
You need host agent 6.x.
Here is a post of my agent.config file on my Management server.
this is located in:
C:\program files\EMC\Navisphere Agent\agent.config
Depending on how your explorer is setup you might not see the extention of the file. If you go to tools,folder options, view tab, uncheck the "hide file extention"
Here is my management server agent.config file.
