SNMP version
5.8.2.10 Multicast
The multicast interface is shown as in Figure 5-30.
Multicast is a transmission mode of data packets. When there is multiple-host to receive the same data
packet, multiple-cast is the best option to reduce the broadband width and the CPU load. The source
host can just send out one data packet to transmit. This function also depends on the relationship of the
group member and group of the outer.
5.8.2.11 Auto Register
The auto register interface is shown as below. See Figure 5-31.
This function allows the device to auto register to the proxy you specified. In this way, you can use the
client-end to access the DVR via the proxy. Here the proxy has a switch function. In the network service,
the device supports a server address of IPv4 or domain.
Please follow the steps listed below to use this function.
Please set the proxy server address, port, and sub-device name at the device-end. Please enable the
auto register function and the device can auto register to the proxy server.
Function
This is a string. It is a command between the manage process
and the proxy process. It defined the authentication, access
control, and the management relationship between one proxy
and one group of the managers. Please make sure the device
and the proxy are the same.
The read community will read/write/access all the objects the
SNMP supports in the specified name. The default setup is
write.
The destination address of the Trap information from the
proxy program of the device.
The destination port of the Trap information from the proxy
program of the device. It is for the gateway device and the
client-end PC in the LAN to exchange information. It is a non-
protocol connection port. It has no effect on the network
applications. It is a UDP port not a TCP port. The value
ranges from 1 to 165535. The default value is 162.
