Typically on a PC, you can set the MTU of the NIC to match the established L2 network MTU. An L3 device can then correct MTU mismatch by IP Fragmentation. Since my switches are in L3 mode, it seems like I should be able to set the MTU for a particular L2 VLAN. Thanks

Port Settings Port forwarding—for a single port, multiple ports or a range of ports—sends traffic inbound on a MTU, or maximum transmission unit, is the size of the largest packet that the network can transmit.

MTU The MTU option specifies the largest packet size permitted for network transmission. Select Enable if you do not want the Router to regulate this packet size (otherwise, leave it set at Disable) and enter the value desired. You should leave this value in the 1200 to 1500 range.

MTU size is necessary to allow the passage of frames larger than 1500. I found the necessary setting on the Admin page to allow Jumbo Frames. So being a layer two switch is not the answer.
The MTU size is a setting that determines the largest packet size that can be transmitted through your system. These packets are measured in octets, or eight-bit bytes. The Transmission Control Protocol determines the maximum packet transmission size based on your MTU settings. I have the same problem Im using the Wrt54G linksys wireless-g router, changed the MTU to 1365, and am failing the xbox live mtu test. The router was fine at 1500, when I had my old motorola surfboard modem, I traded in for a newer model the Sb5120. And so far, no xbox. Dont know what else to do. Xbox customer support is a joke. Comcast is a joke.
