Method and equipment for improving timeout of link aggregation protocol

Abstract

The invention provides a method and equipment for improving timeout of a link aggregation protocol. The method comprises the following steps: setting timeout time and timeout threshold times of receiving an LACPDU packet by a switch; in response to the fact that the first switch receives the LACPDU packet from the second switch for timeout, counting timeout times; judging whether the second switchport is abnormal or not through the network control center in response to the situation that the timeout frequency is greater than the threshold frequency and the switch aggregation link is in an out-of-band management mode; in response to the second switch port exception, the second switch exception port is removed from the aggregated link. By using the scheme of the invention, the problem thatthe stability of in-band management is possibly influenced by the in-band data flow can be avoided, the stability of the aggregation link can be further improved, and the forward compatible elasticityis reserved.

Description

technical field [0001] This field relates to the computer field, and more particularly to a method and device for improving link aggregation protocol timeout. Background technique [0002] Out-of-band management refers to using an independent management channel for device maintenance. It allows system administrators to remotely monitor and manage servers, routers, network switches and other network devices. In contrast, in-band management refers to using regular data channels to manage devices. An obvious limitation of in-band management (In-Band Management) is that such management is vulnerable to attacks or compromises on managed devices. Out-of-band management addresses this limitation by deploying management channels that are physically separated from data channels. [0003] Aggregation link (Link aggregation) is to aggregate multiple physical ports together to form a logical port to realize the load sharing of outbound and inbound traffic throughput on each member po...

Problems solved by technology

In practical applications, the problem often encountered is that the number of packets that can be sent to the CPU per second is limited on the port to avoid CPU overload, and LACPDU packets need to be sent to the CPU for processing. If the network status is unstable , For example, when a broadcast storm occurs or a loop occurs, there will be too many packets on the port that need to be sent to the CPU for processing, such as ARP packets, which will likely crowd out the LACPDU packets, causing the port to misjudge the port. Remove the aggregated link, so that the port on the aggregated link is in an unstable state
