Step 3 Set parameters.

Network Mode : Includes multiple access, fault tolerance, and load balancing

Multiple-address mode: eth0 and eth1 operate separately. You can use the services such as
HTTP, RTP service via etho0 or the eth1. Usually you need to set one default card (default
setup is etho) to request the auto network service form the device-end such as DHCP, email,
FTP and etc. In multiple-address mode, system network status is shown as offline once one
card is offline.

Network fault-tolerance: In this mode, device uses bond0 to communicate with the external
devices. You can focus on one host IP address. At the same time, you need to set one master
card. Usually there is only one running card (master card).System can enable alternate card
when the master card is malfunction. The system is shown as offline once these two cards are
both offline. Please note these two cards shall be in the same LAN.

Load balance: In this mode, device uses bond0 to communicate with the external device. Th e
eth0 and eth1 are both working now and bearing the network load. Their network load are
general the same. The system is shown as offline once these two cards are both offline. Please
note these two cards shall be in the same LAN.

Main Network Card: Please select eth0/eth1 (optional).after enable multiple access
function.
Note
The dual-Ethernet port series support the above three configurations and supports
functions as multiple-access, fault-tolerance and load balancing.

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.
