Abstract
Some embodiments provide a method for diagnosing a logical network that includes several logical forwarding elements (LFEs) that logically connects a number of data compute nodes (DCNs) to each other. The method identifies a set of LFEs that logically connects a first DCN of the several DCNs to a second DCN. The method also identifies a transport node that couples to the first DCN and implements the set of LFEs. The method then, for each LFE in the set of LFEs (i) receives a first state of the LFE from the transport node, (ii) compares the first state of the LFE with a second state of the LFE that is received from a controller of the LFE, and (iii) reports the LFE as a problematic LFE along with the transport node and the controller of the LFE when the first and second states of the LFE do not match.
