Video streams from IPCs are transmitted to the switch. The switch then distributes the video streams to one or multiple C/S clients. Figure 1 shows the direct connection multicast network.
Forwarding multicast
Video streams from IPCs are transmitted to the switch. The switch distributes the video streams to the MPU. Then, C/S clients obtain the video streams from the MPU. Figure 2 shows a forwarding multicast network.

Configuration Data Example
Table 2 lists the parameter value examples involved in this configuration procedure.
Table 2 Configuration data example Parameter Example Value Max. Limit
Multicast IP address
224.0.0.2. The IP address ranges from 224.0.0.0 to 239.255.255.255. If there are multiple MPUs on the network, it is recommended that each MPU match a multicast IP address.
The multicast IP address and port number configured for each camera cannot be the same. For example, if the multicast IP address and port number of No.1 camera connected to VCN1 are 224.0.0.2 and 37112 respectively, the multicast IP address and port number of No.1 camera connected to VCN2 cannot be 224.0.0.2 and 37112 respectively. The multicast IP address and port number of No.1 camera connected to VCN2 can be set to 224.0.0.3 and 37112 respectively.
Multicast port number
37112. The start multicast port number is 37112. The port range matches the MPU's camera access capability, and the difference between every two adjacent port numbers is 6. Among the cameras connected to the MPU, if No. 1 camera uses port 37112, No. n camera uses port 37112 + 6n.
Procedure
Log in to the switch and enable the multicast function. system-view multicast routing-enable
Log in to the C/S client as the admin user.
Double-click Settings on the Workspace tab page of the C/S client, as shown in Figure 3.
Figure 3 Settings
Click the Local Parameters tab.
Enable the multicast function.
Enable forwarding multicast, as shown in Figure 5.
Figure 5 Enabling forwarding multicast
Enable direct connection multicast, as shown in Figure 4.
Figure 4 Enabling direct connection multicast
NOTE:
The value PU direct connect means that a C/S client can directly obtain and display video streams from a PU (signaling is directly transferred from the C/S client to the PU). At present, the C/S client can directly connect only to Dahua GTEK DVR devices through the DHSDK protocol.
Click Save.
Double-click Devices on the Workspace tab page of the C/S client, as shown in Figure 6.

Click the Local Domain tab.
Double-click the camera for which you want to set a multicast IP address and port number, as shown in Figure 7.
