Solution of Shanghai IPTV Single-wire Multiplexing vlan Switch (for sdn Optical Cat)
I didn't do enough homework before, so I bought ASUS AC86U and brushed Merlin, but this router doesn't support vlan division and can't use the open script of Shanghai IPTV single-line multiplexing. After that, we use an 8-port BL-SG 108M vlan separable switch. This switch is cheaper than 100 yuan, supports mirror packet capture, vlan and port isolation. However, the default vlan 1 of the port needs special skills to change, so we can Baidu it ourselves. This article has instructions/thread -87 195-65448. The following figure shows the previous method:

It worked well at first. The TV report 9400 1 system was not too busy, but it was reported too frequently after that, once every few minutes, which affected the normal broadcast of TV and made it impossible to watch it. I can't stand it. I saw SG 105 with five crystal mouths in a certain east. Pro gigabit network management switch is less than 100 yuan, so I started with two switches in one breath. After understanding the principles and rules of vlan, I conducted many experiments. The TV error should be caused by interference when connecting the router or transmitting data to the TV interface. My understanding is that the receiving end of the TV box is particularly sensitive when processing data, and receiving a data packet that is not live or broadcast (it should be intentional by the telecom) will trigger an error. After tossing, the following scheme completely isolates the network data from the TV data, and there is no error report. The specific settings of the two switches are as follows:

Crystal is a switch configuration that supports web pages and clients. The client is more convenient and can automatically find the switching device in the network segment. In the above method, IPTV is connected to port 1 or 2, port 3 is used for single-line multiplexing, and ports 4 and 5 are used for network data. Theoretically, after this setting, there is no need to adjust the optical cat configuration. The specific connection method is as follows:

At this point, it doesn't matter who dials whether it is necessary to change the cat bridge. It can be said that this is the simplest, stable and reliable solution. As long as the two devices are not in 200 yuan, the complicated routing setting function is omitted.

ASUS AC86U has google installed, and the plug-in is installed in Meilin Firmware Center, which is useless. We can consider whether another alternative, clash, is effective. We haven't studied it carefully.
