Oversize (jumbo) frame errors

FYI, AP sends out 1576 bytes frames once per minute just to find out whether the network in between itself and the LMS IP supports jumbo frames. Since this is not really standard on 100BT medium, it can appear as Jabbers, CRC or oversize error. Note that it does not prevent the AP from working perfectly.

When you hardcode the MTU, AP never send jumbo frame and hence no crc/oversize error.

Under 3.x,
1.configuration--> AP Configuration--> Ap group-->edit -->AP-->AP system Profile --> SAP MTU
2. Set the value as 1500 bytes as the max size sent is 1576 bytes in our case.
