After upgrading switches to FOS v9.2.2d, Health Summary page of SANnav 3.0.1/3.0.1a shows degraded status: Fabric is degraded with score of -10 in the Status field. Show Details report the Reason: One or more switches are in degraded health. Switches is degraded with score of -10 in the Status field. Show Details report the Reason: Telemetry Error: CA Root certificate not found on the switch. Performance Monitor or Flow Monitor displays incorrect or is missing value every 15 minutes.
A change in ` seccertmgmt ` command of FOS 9.2.2d prevents SANnav 3.0.1/3.0.1a from retrieving Kafka certificate information from the switches. Because it cannot fetch the certificate, SANnav incorrectly assumes telemetry registration has failed and attempts to re-register every 15 minutes. Each new telemetry connection forces the switch to reset its stream buffer and reinitialize, which skews the stats and results in the incorrect data values.
Install SANnav CSI patch 3.0.1a.1.
