MTU value - GENEXIS Platinum 4410

Please guide to find the path name of MTU in Genexis ONT.
Corresponding to “InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection.1.CurrentMRUSize” which is available in other ONTs I couldn’t identify a path in this. Only in Config file its value is there.
How to edit that value ? Kindly guide.

You don’t, it is a “read-only” value (see tr-098-1-8-0.xml).
Also, Platinum series supports newer TR-069 data model - TR-181, which abandoned the “WAN/LAN” interface model. Location of these parameters has changed.
Look under “Device.­PPP.­Interface.”.
