In our environment, we are having issues with multicasting with Windows Deployment Services when the session goes across one switch. The client network utilization never goes above 5%. When the WDS session does not go through this switch, network utilization hovers around 99%. The switch model is a HP ProCurve 5308XL.
This switch is located in the middle of the network and does not do any routing. It is the only switch of this model that we have. All of our other switches are HP and are either 2650s or 4108GLs.
