US 2019/0199600 A1 · TROUBLESHOOTING VIRTUAL NETWORK REACHABILITY

Abstract

A novel method for troubleshooting a logical network is provided. The logical network has logical forwarding elements operating inside virtual network forwarding engines. The method receives a source identifier and a destination identifier that correspond to nodes in the logical network. The method then retrieves a set of network data from a virtual network forwarding engine and identifies a path in the logical network by traversing the logical network according to the retrieved set of network data. This traversal starts at an initial network node that is identified by the source identifier and continues through a set of next-hop network nodes that are each identified based on the destination identifier. At least some of the network nodes are logical ports associated with logical forwarding elements implemented by the virtual network forwarding engine. The method then reports the set of traversed logical nodes.
