Client Network Traffic tests

These postings are provided "AS IS" with no warranties, and confer no rights.

The following information is for example purposes only. Do not rely on this information for a production deployment. These are meant to show the areas you should test for when evaluating ConfigMgr client activity impact on your network before going into production. The results are specific to the below ConfigMgr configuration and will vary from environment to environment.

UPDATE (22/04/2013): The System Center 2012 Configuration Manager version of this post can be found here:  https://aka.ms/pwlunk

To perform this sort of testing you can use NetMon 3.3, and the Top Users Netmon Expert. Basically, the process is:

  1. Start Capture (easiest in Mixed Mode)
  2. Perform Activity
  3. Stop Capture
  4. Run the Top Users expert

Note on SUP/WSUS traffic: Below is some additional (though less comprehensive) testing performed for this information.

  • Clients pulling metadata from a SUP with Windows Vista and Office 2007 installed have been observed requiring 21MB worth of metadata.
  • Client pulling metadata from a SUP with Windows Vista, Office 2007 and FCS installed have been observed requiring 34MB worth of metadata, with 4MB of upstream (client to server) traffic.
