When posting to the community try to provide a much detail as possible.    Include the error or fault details (not just the error code),  the hardware and/or software versions,  and typology details if relevant.

This will ensure folks are more likely and able to respond intelligently.

Hi, I believe this error code related to IP deatched message

The reason for the this event is due to an incomplete ARP entry getting flushed on a border leaf. The incomplete ARP entry is due to a non existent IP or maybe the end host is down.

In scenarios where this is seen, lets say there is a /24 sub-net defined on the L3out interface 10.10.10.x/24.

The border leaf gets traffic that is destined to a non existent IP (10.10.10.50) in the 10.10.10.x/24 subnet. This creates an incomplete ARP on the BL for this IP address 10.10.10.50 . When the incomplete ARP flushes out after 30 seconds, an IP detached event gets registered.

This event does not have any node information in it so please check any border leaf with this IP subnet.
