1. RSSI 2. SNR 3. Load-Ballancing
same as steps to roaming in non-802.1R except: skips PMK negotiation & piggybacks PTK & QoS with the 802.11 authentication & association messages
1. Allow EAP-MSCHAPv2 2. Allow EAP-GTC 3. Check Posture Validation when doing NAC

2. 802.11R
1. Create user acct. in IDS for each WLC in the viewer role 2. add the WLCs IP as an allowed host 3. Obtain the IPS TLS Fingerprint & add it to WLC 4. Enable the client exclusion policy on the WLAN 5. Set msg log level to Alerts to log IPS events
specifies fast bss transitions by allowing negotiations and requests for wireless resources to occur simultaneously. Does this by allowing for part of the key to be cached (server key) among the network - so full 802.1x auth. isnt required
1. Wireless-->AP Global Config-->enable dot1x w/ user/pass 2. Config the switch port to enable auth. to ACS/RADIUS
Check Shell(exec) then define roles as role1=MANAGEMENT role2=WLAN role3...etc
