Refer to the exhibit. A syslog service was configured to capture different faults and events from a Cisco ACI tenant. The Cisco ACI fabric is missing any OOB capability. After some time, the…

Changing the forwarding facility categorizes syslog messages but does not prevent their transmission if other network and configuration parameters are correct.

Pinging the syslog server from the APIC verifies basic network reachability but does not diagnose application-layer issues like incorrect port configuration or severity filtering.

Syslog communication relies on specific UDP ports; if the configured UDP port on the ACI fabric for syslog does not match the port the syslog server is actively listening on, the messages will not be received. Reconfiguring the UDP port settings to ensure alignment is crucial for successful syslog message delivery.

Syslog configurations often include a minimum severity level, which filters messages based on their importance. If the configured minimum severity level is set too high (e.g., 'critical'), messages of lower severity (e.g., 'informational' or 'warning') will be suppressed and not sent, requiring a change to a lower severity to capture more events.

Setting the management EPG to default is related to management access for fabric nodes and APICs, not directly to the in-band configuration of syslog for tenant events destined for the APIC itself.
