ONTAP reported SwitchIfFlapping_Alert:

Problem Summary: Node-1B SwitchIfFlapping_Alert Ethernet1/23
Detailed Problem Description: Node: Node-1B
           Alert ID: SwitchIfFlapping_Alert
           Resource: Ethernet1/23
           Severity: Degraded
    Indication Time: Tue Jan 27 14:02:13 2026
           Suppress: false
        Acknowledge: false
     Probable Cause: The switch:port switch1(SSI2XXXXXXX):Ethernet1/23 has experienced frequent changes in its operational status over three consecutive polling intervals.
                     This behavior could be due to issues such as unstable
                     connections, hardware malfunctions, or configuration
                     problems.
    Possible Effect: Frequent changes in the operational status of an
                     interface can lead to network instability, increased
                     latency, packet loss, and degraded performance for
                     connected devices.
Corrective Actions: 1) Check the physical connections between the switch
                     and the connected devices. Ensure that cables are
                     properly connected and not damaged.
                     2) Inspect the switch interface configuration for any
                     inconsistencies or errors that may cause the interface
                     to flap. Correct any misconfigurations found.
                     3) Verify the performance and health of the connected
                     devices, as well as the switch itself. Check for any
    hardware issues or malfunctions that may cause the
                     interface to change its operational status frequently.
                    4) Monitor the network traffic on the affected interface
                     to identify any unusual patterns or excessive loads
                     that may contribute to the flapping.
