Technical Field

The invention belongs to the technical field of switch network detection, and particularly relates to a method and a device for realizing error reporting based on a SONiC switch.

Background

SONiC, Software for Open Networking in the Cloud, an Open computing project proposed by microsoft, designed primarily for the use environment of the data center. This item provides a collection of overlay software and can run on different switch hardware through the abstraction layer interface.

ACL is a set of mechanisms for filtering messages and executing specified actions by the abbreviation of Access Control List.

gPCs, an acronym for Google removal Procedure Calls, the remote Procedure call architecture proposed by Google, are transported based on the HTTP/2 protocol.

At present, a Spine/Leaf topological architecture is usually adopted in a mainstream data center, the architecture can easily perform linear expansion on equipment of the data center, and can also bring the advantages of load balance and redundancy.

In a data center, most of the equipment is housed in cabinets. In a large data center, the number of cabinets can reach thousands, and each cabinet can be provided with more than ten switches, and in such a case, if a problem occurs in equipment or a physical line, it is difficult to quickly find out the equipment with the problem for troubleshooting.

Existing link detection technologies such as IEEE 802.3ag, IEEE 802.3ah implement L2 link detection. The ICMP protocol may implement path detection at L3. The existing detection mechanism can only report the problems of L2 and L3 individually, and the information can be received only by the message transmitting end or the device with the problem, so that the information cannot be presented in a unified and centralized way. The conventional diagnostic tools such as Ethernet OAM and IPv4 ICMP cannot effectively and quickly lock the faulty path because of the existence of multiple paths.

Therefore, it is very necessary to provide a method and an apparatus for implementing error reporting based on a SONiC switch to overcome the above-mentioned drawbacks in the prior art.
