Handling Process

check if there is a duplicated capwap vlanif ip on the switch or in the network as found here:


[AC] interface Vlanif21
[AC] description WIFI_capwap
[AC] ip address 10.10.6.135 255.255.255.248
……….
[AC] capwap source interface vlanif21

[SWITCH] interface Vlanif21
[SWITCH] description vlan_management
[SWITCH] ip address 10.10.6.135 255.255.255.248

Root Cause

duplicated ip of capwap vlanif has been the root cause of the unstable status of AP.

Solution

change capwap vlainf21 ip on the AC or change vlanif21 ip on the switch to solve the problem.
