Hi Folks
I had the same problem in just a small environment, just 40 VM’s and 25 workstations. I did not came across your blog about this issue, so I have struggled over a week on this.
Reading always helps a lot!
I just changed the switch to old Cisco 3750 and everything works fine. On all workstation I got file transfer throughput of more than 30 Mbyte/s between routed Vlans.
So what is this HP 1920 actually for? It says it is layer 3, but partially it is not!
We are going to give back the switch to the supplier.
Thanks & Regards,
Boris
