What a crazy stuff it is! Though the price as worth is pretty expensive if I though with a calm mind, it is a unprecedented price-slashing considering |

- | The switch supports dual boot of RouterOS and SwOS, so it can do L3 processing to some extent. Having said that, processes which aren't handled by the chip are processed by CPU, and what is worse, an internal bandwidth between them is only 1Gbps. Therefore, we had better use it as plain L2 switch, or should keep lightweight L3 usage such as connecting to WAN with simple packet | + | The switch supports dual boot of RouterOS and SwOS, so it can do L3 processing to some extent.
