Problem with Agent port

I have two network segments between which there is a switch.

Agent establishes communication with the server via port 1918, but the server communicates with the agent at a random (arbitrary) number of port.Questions are:

If you can limit the range of ports to the agent within some value npr.58000-59000?
Whether and how the agent can specify the correct port for communication?
Whether it can be to tivoli (TEMS) server to limit the ports that will be contacted agent?

Please help!

Regards to all

Hi,

I had the same problem some months ago.

http://www.ibm.com/developerworks/forums/thread.jspa?threadID=259219

You can“t limit the ports the agent uses to send data. It gets it random from the available ports

You just can control the port TEMA uses to listen.

it will typically use port 1918 - to start. However...
The agent migrates to an alternate port after starting. There is an algorithim for this port migration. It is:

1918 + n * 4096

Where "n" is the number of agent on the server that is started. Meaning, if this is the first agent started on a server - n = 1, if this is the second agent started on a server n =2 and so.

Port restrictions can be set using the KDC_FAMILIES variable on the agent.
