Gang, I have an odd problem with transmission speed. Situation:
I have a GE medical imaging device (DICOM) that GE tells me HAS to be set at 100 half duplex on the switch (this switchport is also on a vlan).
Easy enough, affer the switch config, I check the GE Imaging device, and it auto negs at 100 half.
The Tech sends an image, it takes 43 seconds to show up on our pacs server.
NOW THE ODD PART.
Switch port still configured at 100 half. We unplug the GE device from that port, and plug a small dlink hub into that port. Into the hub, we plug the GE device, the GE device auto negs on the hub at 100 full. The tech sends an image to our pacs system, and it takes 5 seconds.
I don't understand why it is doing that, ultimately, the switchport that the hub is pluggd into is still 100 half even though the hub and GE device are at 100 full.
Is the GE Tech on crack, should I be using the device at 100 full?
Also, are there any considerations, configuration changes I need to make for the DICOM protocol?
Thanks a million, I'm stumped.
The details: The Cisco switch is a 3750 running Version 12.1(19)EA1c
