4.10.2.1 TCP/IP
The single network adapter interface is shown as in Figure 4-61 and the dual network
adapters interface is shown as in Figure 4-62
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. A t 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. The eth0 and eth1 are both working now and bearing the network load.
Their network load are general the same. The system is show n as offline once
