Static endpoint validation

Abstract

Systems, methods, and computer-readable media are disclosed for validating endpoint information for nodes in a network. A network assurance appliance is configured to retrieve a configured static endpoint information in a logical model of a network from a network controller and connected static endpoint information from one or more nodes in the network. The network assurance appliance determines that there is an inconsistency based on a comparison of the configured static endpoint information and the connected static endpoint information and generating an event specifying the inconsistency.

What is claimed is: 
     
         1 . A computer-implemented method comprising:
 retrieving endpoint information for one or more nodes in a network;   comparing the endpoint information to identify an inconsistency associated with a connected endpoint; and   identifying the inconsistency when the endpoint information does not include the connected endpoint or when the endpoint information includes the connected endpoint and a flag is not set.   
     
     
         2 . The computer-implemented method of  claim 1 , further comprising:
 generating an event specifying the inconsistency.   
     
     
         3 . The computer-implemented method of  claim 2 , wherein the event is associated with a severity level and an event type, and wherein the event type specifies the inconsistency. 
     
     
         4 . The computer-implemented method of  claim 1 , further comprising:
 providing, based on the inconsistency, a user interface comprising network status information.   
     
     
         5 . The computer-implemented method of  claim 4 , further comprising:
 calculating, based on the inconsistency, a health score for one or more endpoints in the network,   wherein the network status information comprises the health score for the one or more endpoints.   
     
     
         6 . The computer-implemented method of  claim 1 , wherein the one or more nodes in the network includes at least one of a leaf node or a spine node. 
     
     
         7 . The computer-implemented method of  claim 1 , further comprising:
 determining, when the endpoint information includes the connected endpoint, the flag is not set for the connected endpoint; and   identifying a flag inconsistency based on the flag in the endpoint information not being set for the connected endpoint.   
     
     
         8 . The computer-implemented method of  claim 1 , wherein the network is a software-defined network (SDN). 
     
     
         9 . The computer-implemented method of  claim 1 , further comprising:
 determining the one or more nodes via a static endpoint not found in a logical model; and   identifying another inconsistency based on the one or more nodes including the static endpoint not found in the logical model.   
     
     
         10 . A system comprising:
 one or more processors; and   at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the system to:
 retrieve endpoint information from one or more nodes in a network; 
 compare the endpoint information to identify an inconsistency associated with a connected endpoint; and 
 identify the inconsistency when the endpoint information does not include the connected endpoint or when the endpoint information includes the connected endpoint and a flag is not set. 
   
     
     
         11 . The system of  claim 10 , wherein the instructions further cause the system to:
 query the network controller to identify a configured static endpoint in a logical model of the network;   determine the endpoint information does not include the configured static endpoint; and   identify a second static endpoint inconsistency between the logical model and the endpoint information based on the endpoint information not including the configured static endpoint.   
     
     
         12 . The system of  claim 10 , wherein the instructions further cause the system to:
 generate an event specifying the inconsistency.   
     
     
         13 . The system of  claim 12 , wherein the event is associated with a severity level and an event type, and wherein the event type specifies the inconsistency. 
     
     
         14 . The system of  claim 10 , wherein the instructions further cause the system to:
 provide, based on the inconsistency, a user interface comprising network status information.   
     
     
         15 . The system of  claim 14 , wherein the instructions further cause the system to:
 calculate, based on the inconsistency, a health score for one or more endpoints in the network,   wherein the network status information comprises the health score for the one or more endpoints.   
     
     
         16 . A non-transitory computer-readable medium comprising instructions stored therein which, when executed by one or more processors, cause the one or more processors to:
 retrieve endpoint information for one or more nodes in a network;   compare the endpoint information to identify an inconsistency associated with a connected endpoint; and   identify the inconsistency when the endpoint information does not include the connected endpoint or when the endpoint information includes the connected endpoint and a flag is not set.   
     
     
         17 . The non-transitory computer-readable medium of  claim 16 , wherein the instructions further cause the one or more processors to:
 generate an event specifying the inconsistency; and   provide, based on the event, a user interface comprising network status information.   
     
     
         18 . The non-transitory computer-readable medium of  claim 17 , wherein the instructions further cause the one or more processors to:
 calculate, based on the event, a health score for one or more endpoints in the network,   wherein the network status information comprises the health score for the one or more endpoints.   
     
     
         19 . The non-transitory computer-readable medium of  claim 16 , wherein endpoint information includes a configured static endpoint, and wherein the instructions further cause the one or more processors to:
 determine the endpoint information does not include an entry corresponding to the configured static endpoint.   
     
     
         20 . The non-transitory computer-readable medium of  claim 16 , wherein the endpoint information includes a connected static endpoint, and wherein the instructions further cause the one or more processors to:
 determine the endpoint information does not include an entry corresponding to the connected static endpoint.
