Network Switch Discovery pattern does not return the Model, if the unit is not configured as part of a Primary/Secondary StackIssue When discovering Cisco Nexus switches, the Model might not be correctly recorded by the Network Switch Discovery pattern if the unit is standalone and not configured as part of a Primary/Secondary Stack.CauseWhen step 3 of the Network switch pattern does not return a Model there is a failover step in the "Stacked switches" shared library, step 39.11. "Failover for setting the model_id at Master Switch". This step has a condition in it $StackSlave is not empty, meaning that the failover only works when there is a primary/secondary configuration.ResolutionThe "Failover for setting the model_id at Master Switch" seems to work fine when the specific condition is removed so it will be triggered for all switches. A modified copy of this step should be added in an extension section to avoid the problem of skipped updates in future instance upgrades. Modifying the main identification section of out-of-box patterns is never recommended.
