Description (partial)

Symptom:
After moving to RUN state, the wireless client is unable to reach default gateway or network.The client connectivity works randomly after some minutes without any actions.At the same time, other wireless clients associated to the same AP are working fine on the same ssid.

Conditions:
WLC 5520 with 8.9.111.0
DNAC Version: 1.3.0.2
ISE Version: 2.4.0.35, patch 3,5
Switches: C9300-48UXM Cisco IOS XE Software, Version 16.09.03
3800 COS APs

Wireless client is associating to a WLAN configured for CWA, the client authenticates on the portal and moves to RUN state, however when the wireless client is pinging the default gateway we can see the packet is encapsulated as capwap with the destination ip as the WLC management interface instead of VxLAN.
