SRW2048 and Jumbo frames

[winntelecom]

I have a Cisco SRW2048 (Firmware 1.2.2d, boot 1.0.0.05) on which I have enabled jumbo frames but yet when I attempt with a Windows 2003 server to ping the mgmt IP of this switch with a frame over 1472 (ping -f -l 1472 w.x.y.z) I get a response of "Packet needs to be fragmented".  The server is connected to a Netgear gig switch (GS724AT) that has jumbo frames enabled and working as I can talk to other devices using jumbo frames.  Attempts to access the SRW2048 switch fail on packets larger than 1472.  I have also attempted a Windows 7 box using jumbo frames to no success.  The Windows 7 box works when connected to the Netgear switch but when I move the connection back to the SRW2048, jumbo frames on the windows box stop working.

Any help or suggestions would be appreciated.

Thanks.

On the SF-300 and SG-300 for Jumbo to work the Enable Jumbo checkbox must be unchecked. Either I don't understand Cisco logic or it's a bug in the GUI.
