1. WLAN switch unable to communicate with APs due to configured capwap vlan is different with APs at POE switch.
2. Channel engineer has changed WLAN switch capwap VLAN ID without configure POE switch VLAN ID that connected with APs.
3. Once POE switch has rebooted or restart, APs unable to function as normal
Step: Log in to Cisco POE siwtch and configure VLAN ID for APs
sw#conf t
sw(config)#int fa0/20
sw(config-if)#switchport trunk native vlan 1000swconfig-if)#end
sw#copy running-config startup-config
Suggest and inform channel engineer to save configuration at third party switches to ensure APs offline issues.
