Since the local area network is to be extended and must be used in E1 line, then a unknown 10 / 100m turn 4E1 line protocol converter can be used, but only one thing is that when the user who uses the extension line to access the local area network. Multicast applications, such as video on demand, when the one-way data traffic is too large, it will cause the protocol converter to block, and the extension has increased to 2 seconds, but the line does not really interrupt, and even if this user retreats. The blocking problem cannot be automatically disappeared. Even if the reactive protocol converter can also solve the problem, you can see the switch to send multicast data to the port of the connection protocol converter, ask the protocol converter manufacturer, they say that once also met. This problem, but I don't know how to solve it! I found a stupid approach, which is forced to block all the data on the switch, such as using ACL, Deny any, a few minutes, re-letting the switch works normally, then the line returns to normal, but in this way, solve the problem only Can you have a better way?
