The interface is shown as in Figure 4-57.
MTU: It is to set MTU value of the network adapter. 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. That is to say, 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 DVR 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.
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.
LAN download: System can process the downloaded data first if you enable this function. The
download speed is 1.5X or 2.0X of the normal speed.
IP Version: There are two options: IPv4 and IPv6. Right now, system supports these two IP address
format and you can access via them.
MAC address: The host in the LAN can get a unique MAC address. It is for you to access in the LAN. It
is read-only.
IP address: Here you can use up/down button (
) or input the corresponding number to input IP
address. Then you can set the corresponding subnet mask the default gateway.
