Problems solved by technology

[0003] However, in related technologies, when the port is switched from the down state to the up state, due to the time difference between the ports of the devices at both ends of the link joining the aggregation group, it may Packet loss occurs during data transmission. For example, after members at one end join the aggregation group, the traffic will be immediately load-shared to the port, and the traffic will reach the other end. The other end is still in the blocked state (block state) because it has not joined the aggregation group, so the traffic cannot pass so that there is a lot of packet loss

[0026] The first embodiment of the present invention provides a link aggregation port switching method, which can be applied to network equipment.

[0027] image 3 It is a flowchart of a link aggregation port switching method according to an embodiment of the present invention, such as image 3 As shown, the process can include:

[0028] Step 301: When the first port of the link aggregation changes from the down state to the up state, the first port is added to the aggregation link in the ingress direction, and the ingress forwarding state of the first port is set to the forwarding allowed state (forward state).

[0029] Here, the port set on the network device can become the port of link aggregation based on the LACP protocol. The first port of the link aggregation is any port of the aggregation group member; the opposite end of the above-mentioned first port is the corresponding port of the opposite network device , For example, for figure 1 In the architecture shown, when the fi...

[0061] In order to be able to further embody the purpose of the present invention, further examples are given on the basis of the first embodiment of the present invention.

[0062] The application scenario of the second embodiment of the present invention is: the ports set by network device A and network device B are ports that form link aggregation based on the LACP protocol, and on network device A and network device B, the ports of link aggregation include port 1. Port 2 and port 3, port 1, port 2 and port 3 form an aggregated link load forwarding, and port 1 changes from the up state to the down state.

[0063] The CPUs of network device A and network device B monitor the port status of the aggregation link through independent high-priority tasks (for example, once every 10ms); when it finds that port 1 changes from the up state to the down state, immediately notify the chip to be in the aggregation group Delete port 1 from the member to achieve fast switching. The switching ...

[0065] In order to be able to further embody the purpose of the present invention, further examples are given on the basis of the first embodiment of the present invention.

[0066] The application scenario of the third embodiment of the present invention is: the ports set by network device A and network device B are ports that form link aggregation based on the LACP protocol, and on network device A and network device B, the ports of link aggregation include port 1. Port 2 and port 3, port 1, port 2, and port 3 form aggregated link load forwarding. Port 1 and port 2 are always in the up state, and port 3 changes from the down state to the up state. The network device A and the network device B may not be directly connected based on the LACP protocol, and the network device A and the network device B may have a layer 2 network device based on the LACP protocol transparent transmission.

[0067] The CPU of network device A or network device B monitors the port status of the aggregat...

Abstract

An embodiment of the invention provides a link aggregation port switching method, network equipment and a computer storage medium. The method comprises the following steps: when a down state of a first port of link aggregation is changed into an up state, adding the first port into an aggregation link in an entry direction, and setting an entry forwarding state of the first port to be a forwardingpermission state; when that the opposite end of the first port sets the entry forwarding state as a forwarding permission state is determined, adding the first port to the aggregation link in an exitdirection.

Description

Technical field [0001] The embodiments of the present invention relate to but not limited to the field of Ethernet switching equipment, and in particular to a link aggregation port switching method, network equipment, and computer storage medium, which can implement link aggregation ports in the link aggregation control protocol (Link Aggregation Control Protocol, LACP). ) Fast link switching and lossless switchback. Background technique [0002] With the rapid development of computer and network technology and the continuous emergence of various network applications, the stability of basic data communication networks is becoming more and more important. In order to increase bandwidth and realize functions such as link transmission flexibility and redundancy, the connections between switches are generally aggregate ports to realize load sharing of outbound and inbound traffic among member ports. The states of aggregate group members are up and Down state, when the port switches ...
