System may pop up dialog box for you to confirm setup when you want to change MTU setup.
Click OK button to confirm current reboot, or user may click Cancel button to terminate current
modification. Before the modification, user may check the MTU of the gateway; the MTU of the
NVR shall be the same as or is lower than the MTU of the gateway. In this way, user may reduce
packets and enhance network transmission efficiency. Right now, the value here is for read-only.
The following MTU value is for reference only.
1500: Ethernet information packet max value and it is also the default value. It is the typical
