Error Messages FAQ
Q. We have begun the conversion of more than 200 access points (APs)
from Cisco IOS® Software to Lightweight AP Protocol (LWAPP) with a
Cisco 4404 WLC. We have completed the conversion of 48 APs and we
receive a message on the WLC that states: 
[ERROR] spam_lrad.c
4212: AP cannot join because the maximum number of APs on
interface 1 is reached
. Why does the error occur?
A. You must create additional AP−manager interfaces in order to support more than 48 APs.
Otherwise, you receive the error that looks like this:
Wed Sep 28 12:26:41 2005 [ERROR] spam_lrad.c 4212: AP cannot join because 
the maximum number of APs on interface 1 is reached.
Configure multiple AP−manager interfaces and configure primary/backup ports that other
AP−manager interfaces do not use. You must create a second AP−manager interface in order
to bring up additional APs. But, make sure that your primary port and backup port
configurations for each manager do not overlap. In other words, if AP−manager 1 uses port 1
as the primary and port 2 as the backup, AP−manager 2 must use port 3 as the primary and
port 4 as the backup.
Q. I have a Wireless LAN Controller (WLC) 4402 and I use 1240
lightweight access points (LAPs). I am trying to enable 128−bit
encryption on the WLC. When I select 128−bit WEP encryption on the
WLC, I receive an error that says that 128−bit is not supported on the
1240s: 
[ERROR] spam_lrad.c 12839: Not creating SSID mde on
CISCO AP xx:xx:xx:xx:xx:xx because WEP128 bit is not
supported
. Why do I receive this error?
