Symptoms or Error
First Test with policy set to Preferred. [No UDP Ports are opened]
- Launch the Desktop.
- From command prompt browse to “C:\Program Files (x86)\Citrix\System32”
- Run ‘CtxSession’
You can see that TCP is being used with CGP (Session Reliability) and Session Reliability encapsulates the ICA protocol.
Run CtxSession /v for a verbose output. Here you can see the port 2598 being used on the VDA.
Now set the policy to ‘Diagnostic mode’.
Ensure UDP 1494 and 2598 ports open on the VDA I connect back to the Citrix desktop, run CtxSession /v and receive confirmation that we are now using UDP 2598. This means that HDX Enlightened Data Transport is being used with Session Reliability. You can also check Director and note the protocol will be set as UDP.
