I have two Wireless LAN controller en the Networks. One WLC is in the building A and the second WLC is in the building B. The access points installed in the Building A, are registered in the Wireless LAN Controller A, this controller is configured as the primary WLC. The problem is that the access points are registered in the WLCA but sometimes the APS goint to registered to WLCB, the access point remains registered in the WLCB around 10 - 15 seconds, and the access go back to WLCA.
I enter ping command to IP Address Managment of the WLCA, and no paquet loss are showed in the output of the ping command.
So, but Why the access point going to WLCB ?
I have captured the messages in a LAP, this output is available in the attachment file.
The timers in the Wireless LAN Controller A,are as following:
Transferring Crash file from standby: Login to the Active WLC in HA.
From CLI: (Cisco Controller) >transfer upload datatype crash (Cisco
Controller) >transfer upload filename (Cisco
Controller) >transfer upload mode tftp (Cisco Controller) >transfer
