Help with APs dont join to WLC

[KleberMuniz]

I have a 4400 WLC for 100APs running the 7.0.98.0software version.

Now, only 48 APs are joined, and the WLC dont accept new joins.

The log below are from my WLC but appear for all others APs:

%LOG-6-Q_IND: spam_lrad.c:1440 Discarding discovery request in LWAPP from AP 00:3a:98:ae:e3:f0 supporting CAPWAP

Some one know how to resolve this?

Thanks!

Hi,

I bet that you have only one port connected on the WLC ? This is precisely what limits the AP support to 48.

To have 100 AP support you need to enable LAG on the WLC, configure a portchannel on the switch and connect several ports.

Hope it helps.

Precisely!

Put all ports and now I have one beautiful controller with 100 APs.

Next step: WCS

Thank you!
