Symptom
IP-SGP mapping shows entries for IPs that no longer exist on the switch:

Conditions
Behavior is seen on SDA catalyst switches with IOS-XE, enabled as edge.
The issue is triggered when an endpoint already onboarded with assigned IP, VLAN, and SGT has a COA (change of authorization) from ISE and a new VLAN, SGT is assigned.
Workaround
Not workaround at the moment.
