jumbo frames / SG 200-08 / not forwarding

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

That document is not relevant

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.
