the wireless access node port entity comprises at least: a managed entity number attribute field, an operation state attribute field, a management state attribute field, an access frequency band attribute field, a wireless signal strength attribute field, an access channel attribute field and an uplink and downlink negotiation rate attribute field;
the PON access node port entity comprises at least: managed entity number attribute field, operational status attribute field, management status attribute field.
6. The method of claim 1, wherein the master device receiving the slave device's serial number from the AVC notification, completing the slave device's secondary node SN authentication, comprises:
in the case that the AVC notification indicates that the operation state of the slave device is an active state, the master device transmits a query message to query the serial number of the slave device;
the master device receives the serial number reported by the slave device;
the master device performs the SN authentication on the slave device.
7. The method of claim 6, wherein the master device performing the SN authentication of the slave device comprises:
under the condition that the SN authentication of the slave device by the master device is successful, the master device initiates MIB synchronization to the slave device;
and under the condition that the SN authentication of the slave device by the master device fails, the master device takes the slave device offline.
8. The method of claim 1, wherein after the master device initiates master information block MIB synchronization to the slave device, the method further comprises:
the master device sends a configuration instruction or a query message to the slave device;
and the master device receives the alarm information or the AVC notification reported by the slave device.
9. A computer readable storage medium, characterized in that a computer program is stored in the computer readable storage medium, wherein the computer program, when executed by a processor, implements the method of any of claims 1 to 8.
10. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method of any of claims 1 to 8 when executing the computer program.
