A configuration method for port aggregation of a cloud platform switch

Abstract

The present invention provides a configuration method for cloud platform switch port aggregation, including: configuring at least two physical machine switches as a stacking switch forming at least one stacking link; dividing a stacking switch composed of several virtual ports and supporting north-south direction LACPDU Two groups of LACP link aggregation ports for message unicast, when LACPDU messages are unicast and responded between the physical machine switch and the server, modify the SYSTEM_ID field of the LACPDU message and response message to the local MAC address through the application program . In the present invention, there is no need to use two sets of physical stacking switches to complete the LACP protocol negotiation for load balancing of physical server clusters and link monitoring, which reduces the complexity of network deployment in the data center and saves the cabinet space of the data center, thereby significantly reducing It reduces the cost of network equipment in the data center, realizes the effects of load balancing and bandwidth expansion, and improves the scalability of the cloud platform.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a configuration method for port aggregation of a cloud platform switch. Background technique [0002] Port aggregation is to aggregate multiple ports together to form an aggregation group, so as to realize load sharing among member ports and provide higher connection reliability. Port aggregation can be divided into manual aggregation, dynamic lacp aggregation and static lacp aggregation. The basic configuration of ports in the same aggregation group should be consistent, that is, if a port is a trunk port, other ports are also configured as trunk ports; if the link type of this port is changed to an access port, the link types of other ports are also configured as Change to access port. [0003] In the cloud platform, server clusters constructed by multiple computing nodes are often used to realize the forwarding of complex inter-network message data, and usually rely ...

Problems solved by technology

[0006] However, generally, the server cluster that uses servers to forward complex data packets will not be too large, and the port aggregation using lacp will limit the number of server clusters to no more than 16 physical servers, so using two sets of stacked switches will cause more The stacking switch ports are wasted, especially the current 10 Gigabit port switches are expensive, and at the same time, the switches in the data center also need to occupy the space of the cabinet for placement, resulting in waste of cabinet space in the data center, resulting in higher investment in the data center
