In the last couple of weeks, I have been trying to setup a NM-AIR-WLC6-K9 on a 2811 router.
I tried various setup combinations as described in :-
My network is very simple (just a few subnets with a router on a stick in between) , and initially I wanted to place all the wireless clients in the same subnet as the wired clients.
The only way I could get that to work, was by using BVI and sub-interfaces on the 2811 hosting the NM-WLC. (This 2811 is not the default gateway / router-on-a-stick. I have another router that enables routing between subnets.)
While that works, I have a problem with SNMP replies packets that get sent from the NM-WLC to wired/wireless subnet.
Finally, I have come to the conclusion (perhaps incorrectly, and therefore this post), that the best way to set wireless clients is :-
1. To have them in their own separate subnets.
2. Have a separate subnet for the WLC
So for example:-
Data Net :- 10.1.1.0/24 (wired)
Voice Net :- 10.1.2.0/24 (wired)
Wireless Net :- 10.1.3.0/24 (wifi)
Network for WLC Management and AP :- 10.1.10.0/24 (wlan-controller subnet)
Can anyone who uses a NM-WLC please share their thoughts ?
