Embodiment 1

[0028] Embodiment 1, when the network device connection structure shown in FIG. 1 and the port aggregation device shown in FIG. 2 are adopted, the process of creating a static LAG in this embodiment is shown in FIG. 3 . In this embodiment, it is assumed that neither the network device 11 nor the network device 12 has created a static LAG. With reference to FIG. 3 , this embodiment includes the following steps:

[0029] In step s301 , the static port aggregation processing unit 21 of the network device 11 creates a static LAG1 including port 1 and port 2 of the network device 11 .

[0030]In step s302, the peer state detection unit 22 of the network device 11 judges whether there is a port in the static LAG1 that is connected and full-duplex. If yes, go to step s303, otherwise go to step s305. In this embodiment, both port 1 and port 2 of the network device 11 are connected and in a full-duplex state, so go to step s303.

[0031] In step s303, the peer state detection unit 22 ...

Embodiment 2

[0034] Embodiment 2, when the network device connection structure shown in FIG. 1 and the port aggregation device shown in FIG. 2 are adopted, the process of deleting a static LAG in this embodiment is shown in FIG. 4 . In this embodiment, it is assumed that the network device 11 creates a static LAG1 including port 1 and port 2 of the network device 11 ; the network device 12 creates a static LAG2 including port 1 and port 2 of the network device 12 . Referring to Fig. 4, the process of deleting static LAG1 in this embodiment includes the following steps:

[0035] In step s401, the working state detection unit 24 of the network device 11 judges whether the port 1 and the port 2 of the network device 11 are in the working state. If yes, go to step s402, otherwise go to step s404. In this embodiment, the port 1 of the network device 11 is in the working state, and the port 2 is in the non-working state. Taking the processing of port 1 as an example, because port 1 is in worki...

Embodiment 3

[0040] Embodiment 3, when the network device connection structure shown in FIG. 1 and the port aggregation device shown in FIG. 2 are adopted, the flow of deleting member ports in this embodiment is shown in FIG. 5 . In this embodiment, it is assumed that the network device 11 creates a static LAG1 including port 1 and port 2 of the network device 11 ; the network device 12 creates a static LAG2 including port 1 and port 2 of the network device 12 . Referring to Fig. 4, the process of deleting the port 1 of the network device 11 in the present embodiment includes the following steps:

[0041] In step s501, the working state detection unit 24 of the network device 11 judges whether the port 1 of the network device 11 is in the working state. If yes, go to step s502, otherwise go to step s504. In this embodiment, the port 1 of the network device 11 is in the working state, so go to step s502.

[0042] In step s502, the information setting unit 26 of the network device 11 sets ...

Abstract

The disclosed method for converging port comprises: when building a static LAG, the local port decided whether there is port receiving the converging message; if yes, determines the port state according to the link aggregation control protocol standard; or else, holding state for loading business. This invention has no effect on original port business, and can reduce the effect time when cancelling the static LAG or port member.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a port aggregation method and device. Background technique [0002] Port aggregation is a technology that bundles multiple physical ports into one logical port. This technology can treat multiple physical connections as a single logical connection, allowing two network devices to be connected in parallel through multiple ports. Simultaneously transfer data to provide higher bandwidth and greater throughput. Generally speaking, the maximum bandwidth of two ordinary network devices depends on the connection speed of the media (for example, 100BAST-TX twisted pair is 200Mbps), and the use of port aggregation technology can bundle four ports with a speed of 200Mbps to become one Connections with speeds up to 800Mbps. This technology improves the bandwidth by bundling multiple ports, and its increased cost is only the ordinary Category 5 network cable used for connection an...
