I use Catalyst 6513 (Router IOS) + IDSM-2 and use Cisco VMS 2.3 to manage IDSM-2. I upgrade IDSM-2 from version 4 to version 5. However, after updating completely, I use Cisco VMS 2.3 to query to IDSM-2, I see a error:
"status: Error importing configuration files from the sensor - Unable to get sensor version from the sensor. Possible reason: X.509 certificate is invalid or sensor version was downgraded. "
