Notifying method and network device for member terminal port configuring condition

Abstract

The present invention discloses a method of informing configuration situation of member ports. The method comprises steps that a network device sends LACP messages immediately to the opposite port of a member port when the configuration of the member port is changed from consistency with an aggregation port to inconsistency with the aggregation port, and aggregation bits and synchronization bits in the LACP messages are all set into 0; the network device judges whether the aggregation bits and synchronization bits in the received LACP messages are all 0 after receiving LACP messages from other network devices, if true, the member port of receiving the LACP messages is set into a un-selected state. The present also discloses a network device. According to the present invention, the configuration change of a member port can be informed to the opposite port immediately.

Description

technical field [0001] The invention relates to link aggregation technology, in particular to a method for notifying configuration of member ports and a network device. Background technique [0002] Link aggregation technology is a method of bundling a group of physical ports on a network device together as a logical port to increase data transmission bandwidth. The physical ports bundled together are called an aggregation group, and the ports in the aggregation group are called member ports. An aggregation link is formed between the aggregation groups of two network devices, and the multiple physical links included in the aggregation link are called member links. see figure 1 A schematic diagram of link aggregation is shown. Such as figure 1 As shown, the aggregation group on network device 1 includes member ports 11 , 12 and 13 , and the aggregation group on network device 2 includes member ports 21 , 22 and 23 . The aggregation groups of the two network devices commu...

Problems solved by technology

[0006] But the defect of this kind of stop sending LACP protocol message is: because LACP protocol stipulates that the port timeout period is 3 long periods plus 3 short periods, wherein the long period is 30 seconds, and the short period is 1 second

[0008] It can be seen that in the prior art, when the configuration of the member port of the local end is changed, the peer end cannot be notified of the event quickly, so that the peer end cannot timely determine the selected state of the member port according to the change
