1. How is the CAPWAP tunnel between AP & WLC encrypted
x509v3 certificate
WLC generates a Message Integrity Check Information Element (MIC IE) - which includes a sequence # - and aps add it to each mgmt frame. Clients ignore this IE - as they do not understand it.
RSN Tag. Auth Key mgmt will show PSK - or WPA (for 802.1x) Stands for Robust Security Network
1. Off (default) - moves down list and uses next server indefinately. 2. Passive -- Upon failure - server is marked as inactive for (300 seconds) then is put back in list and tried again (if its highest priority). 3. Active -- Actively probes failed

2. How is IBN implemented on a WLAN
Corrospond to top-menu GUI items (wireless - security - monitor etc)
checking allow aaa over-ride in the wlan-->advanced.
It handles .1x & NAC auth. with Single Sign on. WLC forwards RADIUS accounting messages (of EAPOL Success) to the NAC upon login - authing the client to nac - & then it goes through posturing
when you want some wlcs to be part of the same mobility group - but not others.

3. Steps to auth with NAA w/ SSO
based on auth. group -1. vlan 2. qos 3. acl 4. tunnel attributes
1. on NAS create an oob profile for the WLC 2. Create a new device in NAM - specifying the WLC mgmt ip 3. device mgmnt-->NAS & add the NAS ip as an oob virt. gateway 4. still on nams nas config page - enter the nas trusted int. ip & untrusted int vla
