Maximum Transmission Unit (MTU):
A maximum transmission unit (
MTU
) is the largest packet or frame size,
specified in octets (eight-bit bytes) that can be sent in a packet- or frame-based network such as the internet. The
internet's transmission control protocol (TCP) uses the MTU to determine the maximum size of each packet in any
transmission.
The value ranges from 1280-7200 bytes. The default setup is 1500 bytes. Please note MTU
modification may result in network adapter reboot and network becomes off. MTU modification can affect current
network service. 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 you can click Cancel button to terminate current modification. Before
the modification, you can 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, you can reduce packets and enhance network transmission efficiency.
The following MTU value is for reference only. Please note,
PPPoE is not supported.
1500: Ethernet information packet max value and it is also the default value. It is the typical setup when
there is no PPPoE or VPN. It is the default setup of some router, switch, or the network adapter.
1492: Recommend value for PPPoE
1468: Recommend value for DHCP.
