In Non-standalone (NSA) networking, X2 self-setup between a gNodeB and an eNodeB requires that the gNodeB and eNodeB be managed by the same OSS. Because gNodeB and eNodeB are managed by the same OSS, the OSS can configure the X2 self-setup parameters, such as the X2 self-setup switch, the X2 interface IP address, and the X2 self-setup trigger conditions. Only when the gNodeB and eNodeB are managed by the same OSS and configured with the same X2 self-setup parameters, the gNodeB and eNodeB can establish an X2 self-setup connection.

According to Huawei's documentation, the STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU. It is used to check whether the feeder cables of different antennas are connected to the correct ports. The command can be executed on the AAU to detect crossed feeder connections and ensure that the feeder cables are connected to the correct ports.

In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol. This means that all devices that are involved in transmitting the synchronization signal, such as routers and switches, must be able to process and pass on the IEEE 1588V2 messages. If any device in the path of the synchronization signal does not support the IEEE 1588V2 protocol, it will not be able to process and forward the messages, and the overall synchronization will be affected.
