  • Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM)

Known Affected Releases

2.100 DNAC1.1.2 DNAC1.2

Description (partial)

Symptom:
1. Loading the certificate page under "System Settings->Settings->Certificate" in DNAC UI displays a red bar at the top with an error "Something went wrong while loading certificate 500 internal server error". The certificate fields in this page show blank values.

This problem impacts the DNAC deployments that use a 3rd party CA issued certificate as well.

Conditions:
This occurs whenever the default DNAC cert(subject CN=kong) in DNAC-1.1.2 is regenerated by maglev. Following are the two situations when maglev regenerates the default DNAC cert:
1. New nodes join the cluster so that the IP of the new nodes are added to DNAC cert SAN.
2. maglev-config update is executed to update the IP address of any of the interfaces or VIP configuration on the DNAC cluster.
