comparing the number of the acquired ports with the number of the physical ports, wherein the initial value of the number of the acquired ports is 0;
if the number of the acquired ports is smaller than the number of the physical ports, determining that the number of the ports to be requested of the data attribute is the difference value between the number of the physical ports and the number of the acquired ports;
comparing the number of the ports to be requested with the maximum number of the ports acquired once of the data attribute;
if the number of the ports to be requested is larger than the maximum number of the ports acquired once, determining that the number of the ports requested once is the maximum number of the ports acquired once;
and if the number of the ports to be requested is smaller than or equal to the maximum number of the ports, determining the number of the ports to be requested of the one acquisition request as the number of the ports to be requested.
3. The method of claim 2, wherein prior to comparing the number of ports to be requested to the maximum number of ports for one acquisition of the data attribute, the method further comprises:
acquiring the maximum occupied byte number of the data attribute;
and determining the maximum port number acquired at one time as the ratio of the preset maximum transmission unit occupied byte number to the maximum occupied byte number of the data attribute.
4. The method according to claim 2, wherein after receiving the response message returned by the network element device, the method further comprises:
and updating the number of the acquired ports to be the sum of the actual number of the ports recovered by one acquisition and the number of the acquired ports.
5. A port data acquisition device, comprising:
the first acquisition module is used for acquiring equipment data of the network element equipment according to the network segment address, wherein the equipment data comprises: physical address, number of physical ports, virtual interface network address;
the determining module is used for determining a virtual interface network address as a network communication address according to the physical address in the equipment data;
the connection establishment module is used for establishing connection with the network element equipment according to the network communication address;
the second acquisition module is used for acquiring port data of the network element equipment based on a simple network management protocol SNMP;
wherein, the second acquisition module includes: a sending submodule, configured to send a getblock request for the SNMP acquisition operation to the network element device, where the getblock request carries a data attribute, and collects the number of ports of the request at a time;
a receiving sub-module, configured to receive a response message returned by the network element device, where the response message carries port data corresponding to the data attribute and an actual port number of a primary acquisition reply;
wherein the apparatus further comprises:
an acquisition sub-module for acquiring the data attribute;
and the determining submodule is used for determining the port number of the one-time acquisition request according to the acquired port number of the data attribute and the physical port number of the network element equipment.
6. A computer-readable storage medium, characterized in that the storage medium has stored therein a computer program, wherein the computer program is arranged to execute the method of any of claims 1 to 4 when run.
7. An electronic device comprising a memory and a processor, characterized in that the memory has stored therein a computer program, the processor being arranged to run the computer program to perform the method of any of the claims 1 to 4.
