OSPF discovery is not working; Receive "resources.sm_errors" when clicking on "Discover All" in OSPF

Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

OSPF discovery is not working in Smarts Network Protocol Manager (Smarts NPM)

Receive the following error when clicking on Discover All in NPM/Smarts NPM OSPF:

com.smarts.store.SmstoreException: class "com.emc.cmp.dmt.resources.sm_errors$SM_et"s signer information does not match signer information of other classes in the same package

Environment

SMARTS - All supported releases

Cause

No source AM domain has been configured in NPM. You cannot perform a Discover All in OSPF until you have added a source AM domain.

Resolution

To resolve this issue, use the "Add Source" function in the NPM interface to add the source AM domain, and retry the Discover All operation. Once the AM domain has been added the error message should no longer appear and discovery should work. For more information on using the "Add Source" function, see the Network Protocol Manager Discovery Guide.
