Cisco Bug: CSCvu16458 - ESC AA: Follower node deployment notifications can be dropped
Sep 24, 2020
- Cisco Elastic Services Controller
Known Affected Releases
5.0 5.1 5.2
Symptom: When ESC is deployed in an AA configuration, the NB deployment management interface (ETSI/confd based) is homed by the AA cluster leader node which provides NB interface access to follower nodes through proxy connections. When AA health monitoring running on the leader declares a follower unhealthy, the NB proxy connections to the follower are terminated. In some cases AA health monitoring can be too aggressive in declaring a follower node unhealthy. When this happens NB notifications from a follower can be dropped preventing critical VNF lifecycle events from reaching the ESC VNFM and ultimately the external NFVO. Conditions: The behavior exhibits when a follower node is loaded which in turn can degrade the responsiveness of the health check interface utilized by the leader.
