Does anyone have jumbo frames running on this switch?
Using ICMP Echo as my test protocol, I can reach 1552 bytes in frame size ... but at 1553 and beyond (1578, 1932, 2090, 4138, 8978, 9014) , the switch swallows them.
When I physically swap out the SG 200-8 with an HP-1810 configured to support jumbo frames, those frame sizes above slide through just fine, and ICMP Echo Replies return just fine.
On the SG-200, I'm using Administration.., Port Management, Port Settings, {click on a port}, Edit... to modify MTU size. I don't see any 'Enable Jumbo Frames' box that wants checking anywhere.
SG 200-08
Boot version 1.0.0.12
Firmware version 1.0.7.4

Hi,
SG200-08 don't support Jumbo frames.Only SG200-24 and SG200-48 models will support jumbo frames.

That document is not relevant to the OP's issue. That document is referring to other SLM switches, not SG switches. The SG-200-08 DOES support jumbo frames (hence the setting to change MTU to 9000+), however, there is a security feature blocking pings over 1500. I don't know how to disable that setting. In fact, if anyone knows that would be a huge help.

Use the web configuration utility to configure jumbo frames, and choose Port management > Port Settings and choose Security > Denial of Service Prevention > Security Suite Settings to configure DoS prevention.
Maybe disabling the DdoS Prevention is a workaround?
