Cisco Bug: CSCvt87610 - eWLC Telemetry in connecting state on 3node cluster after upgrade from 1.3.3.3 to 1.3.3.4

  • Cisco UCS C-Series Rack Servers

Known Affected Releases

v2.0.3

Description (partial)

Symptom:
The eWLC telemetry connection will remain in the Connecting state, and no Assurance data corresponding to the eWLC is displayed in Cisco DNA Center. Alternatively, Assurance data for an eWLC can go missing, then recover by itself, depending on whether the node running the collector-iosxe-db service and the master node (the one which holds the VIP) are the same.

Conditions:
Assurance upgrades from 1.3.3.3 --> 1.3.3.4 may see this issue because of maglev's limitation on honoring externalTrafficPolciy from the new package.
