Dual Ethernet

Description

When a Dahua product is listed as having two Ethernet ports (not to be confused with PoE ports), this means the system is capable of being on two separate networks, having redundant Ethernet ports, or load balancing the Ethernet ports.

Prerequisites

  • Dahua Recorder with two Ethernet Ports
  • Network Mode : multiple access, fault tolerance, and load balancing

Multi Address

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.

Fault Tolerance

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 Balancing

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 shown as offline once these two cards are both offline. Please note these two cards shall be in the same LAN.

Default Network Card

Default Network Card: Please select eth0/eth1/bond0(optional) after enable multiple-access function

Main Network Card

Main Network Card: Please select eth0/eth1 (optional).after enable multiple access function.
