WLAN ID 1 or 2 does not exist.

Hi,

This error  "%LWAPP-3-REPLAY_ERR: spam_lrad.c:40145 The system has received replay error on slot 0"will be triggered when the AP received an illegal radio frame from the clients. This could be due to the client driver issue. Please update the client drivers and then monitor the WLC for this messages.

Regards,

Divya

Hi Divya,

perfect. Many thanks for the information.

We currently do have some client issues. We'll try to change the clients supplicant/driver.

Regards,

Michael

Do you have dynamic interface configured as AP manager?

Not sure if you are hitting this bug.. it affects only 5520 or 8500WLC
