STP and ACI: Intermittent packet loss due to TCNs

One issue that can arise when we connect ACI and Legacy STP environments is intermittent packet loss to ACI endpoints due to Spanning-tree TCNs. TCNs will trigger ACI to flush endpoints in the EPG on which the TCN was received. ACI does re-learn the endpoints based on normal data-plane learning, but if the TCNs are … More STP and ACI: Intermittent packet loss due to TCNs
