 +It is recommended to first verify that Diretta operates correctly with the default MTU value of 1500 before changing the MTU setting.
 +
 +In Eunhasu, the MTU value can be configured under System Config → Ethernet.
 +
 +When increasing the MTU value, all devices on the network (Host, Target, switches, routers, etc.) must support the configured value.

 +===== How to Configure MTU for Jumbo Frame (sMS-2000 / sMS-1000SQ) =====
 +
 +The following steps describe how to increase the MTU value to use Jumbo Frame on sMS-2000 / sMS-1000SQ.
 +
 +1. First, verify that music playback works correctly via Diretta with the default MTU value of 1500.
 +
 +2. Go to System Config → Ethernet and set the MTU value to either 4088 or 9014. 
 +(Only configure this in a network environment that supports jumbo frames.)
 +
 +3. Click Save & Reboot to restart the system.
 +
 +4. After rebooting, go to the Diretta Config page and configure the following : 
 +  * Diretta Target MTU : Set this to the same value as, or lower than, the MTU value configured in System Config.
 +  * Diretta External MTU : Set this to the same MTU value configured on the Diretta Host device (such as a PC or another Eunhasu device).
 +
 +5. Complete the remaining Diretta settings, save the configuration, and start Diretta to begin playback.
