What is CAPWAP?
• CAPWAP: Control and Provisioning of Wireless Access Points is used
between APs and WLAN controller and based on LWAPP over IPv4 or
IPv6
• CAPWAP carries control and data traffic between the two
• Control plane is DTLS encrypted
• Data plane is DTLS encrypted (optional)
• LWAPP-enabled access points can discover and join a CAPWAP
controller, and conversion to a CAPWAP controller is seamless
• CAPWAP is not supported on Layer 2 mode deployment

Mobility Defined
• Mobility is a key reason for wireless networks
• Mobility means the end-user device is capable of moving location in the
networked environment
• Roaming occurs when a wireless client moves association from one AP and re-
associates to another, typically because it’s mobile!
• Mobility presents new challenges:
• Need to scale the architecture to support client roaming—roaming can occur
intra-controller and inter-controller
• Need to support client roaming that is seamless (fast) and preserves security
12BRKEWN-2010
13. © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public
Scaling the Architecture with Mobility Groups
• Mobility Group allows controllers to peer with each other to support seamless
roaming across controller boundaries
• APs learn the IPs of the other members of the mobility group after the CAPWAP
Join process
• Support for up to
24 controllers,
24000 APs per
mobility group
• Mobility messages
exchanged
between
controllers
• Data tunneled between
controllers in EtherIP (RFC 3378)
• 7.6 has the option of using EOIP or
CAPWAP tunnels between controllers

How Long Does an STA Roam Take?
• Time it takes for:
• Client to disassociate +
• Probe for and select a new AP +
• 802.11 Association +
• 802.1X/EAP Authentication +
• Rekeying +
• IP address (re) acquisition
• All this can be on the order of seconds… Can we make this faster?
15BRKEWN-2010
16. © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public
Roaming Requirements
• Roaming must be fast … Latency can be introduced by:
• Client channel scanning and AP selection algorithms
• Re-authentication of client device and re-keying
• Refreshing of IP address
• Roaming must maintain security
• Open auth, static WEP—session continues on new AP
• WPA/WPAv2 Personal—New session key for encryption derived via standard
handshakes
• 802.1x, 802.11i, WPA/WPAv2 Enterprise—Client must be re-authenticated and new
session key derived for encryption

How Are We Going to Make Roaming Faster?

Roaming: Inter-Controller
• L3 inter-controller roam: STA moves association between APs joined to the different
controllers but client traffic bridged onto different subnets
• Client must be re-authenticated and new security session established
• Client database entry copied to new controller – entry exists in both WLC client DBs
• Original controller tagged as the “anchor”, new controller tagged as the “foreign”
• WLCs must be in same mobility group or domain
• No IP address refresh needed
• Symmetric traffic path established -- asymmetric option has been eliminated as of 6.0
release
• Account for mobility message exchange in network design
21. © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public 21BRKEWN-2010
Designing a Mobility Group/Domain
• Less roaming is better – clients and apps are happier
• While clients are authenticating/roaming, WLC CPU is doing the processing –
not as much of a big deal with latest controllers which has dedicated
management/control processor
• L3 roaming & fast roaming clients consume client DB slots on multiple
controllers – consider “worst case” scenarios in designing roaming domain size
• Leverage natural roaming domain boundaries
• Mobility Message transport selection: multicast vs. unicast
• Make sure the right ports and protocols are allowed

Cisco Centralised Key Management (CCKM)
• Cisco introduced CCKM in CCXv2 (pre-802.11i), so widely available, especially with
application specific devices (ASDs)
• CCKM ported to CUWN architecture in 3.2 release
• In highly controlled test environments, CCKM roam times consistently measure in the 5-8
msec range!
• CCKM is most widely implemented in ASDs, especially VoWLAN devices
• To work across WLCs, WLCs must be in the same mobility group
• CCX-based laptops may not fully support CCKM – depends on supplicant capabilities
• CCKM is standardised in 802.11r, Apple iOS 6.0, iOS 7.0

Protocols that Help Your BYOD Roam
• Issues will come as you reach the edge of the cell – you need to expedite the
jump to the next cell:
• 802.11k: helps the BYOD discover the next cell
• 802.11r (FT): helps the BYOD exchange credentials fast while roaming
• 802.11v BSS Transition Management: pushes the BYOD to the next cell
• How do you know if your BYOD supports 802.11k or 802.11r?
• Apple devices support both since IOS 6
• On Android… it depends on the device – vendors certify for 802.11r and/or 802.11k
devices targeted for the enterprise market, not for the home market
• Two URLs can help you:
• http://www.cisco.com/c/en/us/td/docs/wireless/controller/
technotes/8-0/device_classification_guide.html
• http://clients.mikealbano.com/ (look for RM fields in
frame captures for 802.11k support)

Foundation 1: Enhanced QoS for iOS Devices
• Wireless is becoming the new edge of
the network
• Real-Time apps (voice and video) are
becoming the norm on WLANs
• Endpoint vendors QoS implementation
is weak, resulting in poor quality voice
and video experience over wireless

Wi-Fi’s Biggest QoS Challenge:
Shared, Half-Duplex and Contention Based!
• Only one station can send at a time, or it will
cause interference!
• All stations must first wait for the medium to go
quiet before attempting to transmit.
• What happens when you arrive at a 4-Way Stop?

As more clients associate and
transmit, WLAN contention
increases for all clients. Retry
attempts increase and each
station spends more and more
time in the “waiting and listening”
state, driving down performance

Foundation 2: Improved Roaming Performance
In 802.11, delay in roaming causes poor
experience, especially for rich-media real-
time applications. Interoperability increases
complexity and prevents adoption.

destination
• Today IT Administrators can classify
traffic ONLY at the access point. this
implies:
• Inability to prioritise between the client
and the AP.
• Burden on IT administrator to manage
the applications across the enterprise

Applications
White List
*By default, all applications are whitelisted. This means that if there is no profile,
all apps get QoS. If there is a profile, only the apps in the profile get QoS
QoS Profile is pushed to the Apple iOS device
using standard iOS Profiling techniques (MDM,
email, Web-based, etc.) This profile has a white list
of applications to be marked with QoS. All other
traffic from the Apple device will be sent as best

Controller Redundancy
• Redundant WLC in a geographically
separate location
• Layer-3 connectivity between the AP
connected to primary WLC and the
redundant WLC
• Redundant WLC need not be part of
the same mobility group
• Configure high availability (HA) to
detect failure and faster failover
• Use AP priority in case of over
subscription of redundant WLC

Controller Redundancy – High Availability
• High Availability Principles :
ð AP is registered with a WLC and
maintain a backup list of WLC.
ð AP use heartbeats to validate WLC
connectivity
ð AP use Primary Discovery
message to validate backup WLC list
ð When AP loose 3 heartbeats it start
join process to first backup WLC
candidate
ð Candidate Backup WLC is the first
alive WLC in this order : primary,
secondary, tertiary, global primary,
global secondary.
ð AP does not re-initiate discovery
process.
56BRKEWN-2010
Primary WLC
Secondary WLC
New Timers 7.2
Heartbeat Timeout 1-30 secs
Fast Heartbeat Timer 1-10 secs
AP Retransmit Interval 2-5 secs
AP Retransmit with FH Enabled 3-8 Times
AP Fallback to next WLC 12 secs
57. © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public
Stateful Switchover (SSO)
• True Box to Box High Availability i.e. 1:1
• One WLC in Active state and second WLC in Hot Standby state
• Secondary continuously monitors the health of Active WLC via dedicated link
• Configuration on Active is synched to Standby WLC
• This happens at startup and incrementally at each configuration change on the Active
• What else is synched between Active and Standby?
• AP CAPWAP state in 7.3 and 7.4: APs will not restart upon failover, SSID stays UP – AP SSO
• Active Client State in 7.5: client will not disconnect – Client SSO
• Downtime during failover reduced to 5 - 1000 msec depending on Failover
• In the case of power failure on the Active WLC it may take 350-500 msec
• In case of network failover it can take up to few seconds
• SSO is supported on 5500 / 7500 / 8500 / WiSM-2 and 5760

• WiSM-2 : single 6500 chassis OR different chassis using VSS setup/extending redundancy VLAN.
• RTT latency on Redundancy Link : 80 milliseconds or less. 80% of keep alive timer.
• Preferred MTU on Redundancy Link : 1500 or above.
• Bandwidth on Redundancy Link : 60Mbps or more.
• Recommended to have Redundancy Link and RMI Connectivity between WLCs on different switches
or on different L2 networks
• Keep alive/Peer Discovery timers should be left with default timer values for better performance
• Default box failover detection time is 3 *100 = 300+60 = 360 +jitter (12 msec)= ~400 msec

Why Do You Need AVC ?
Visibility
Threats (worms and Trojans) move laterally (east-west). Central
application sensor will not see this at all
Detection
Path to server may be different than return path—may not be able to
determine application
Troubleshooting
Essential to have visibility at multiple points to break down the problem
and get to resolution faster
Control
Latency metrics such as response time, transaction time, network
and application delay needed to control the apps

CAPWAPv6
• AP can get IPv6 addresses from
state-full DHCPv6/SLAAC or static
assignment
• If statically assigned, the gateway can
be the unique global or Link-Local
address of the router
• Either CAPWAPv4 or CAPWAPv6
can be used, but not both
• APs in bridge mode do not support
CAPWAPv6
112. © 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public
AP Failover
• Management IP address must be
reachable
• One entry per WLC
• The AP will join either IPv4 or IPv6
address of the WLC (regardless of
management IP listed)
• All other AP Failover behaviour is the
same as previous versions

IPv6 Guest Access
• Virtual IP address is IPv4 only
• Uses IPv4-Mapped address for IPv6 web-authentication clients
• Virtual IP should be the same for all WLCs in the same mobility group
• For example the IPv6 address will display as [::ffff:192.0.2.1]

Standalone Mode When FlexConnect AP cannot reach Controller, it goes into
standalone state and does client authentication by itself.
Local Switching Data traffic switched onto local VLANs for an SSID
Central Switching Data traffic tunneled back to WLC for an SSID
Connected Mode When FlexConnect AP can reach Controller, it gets help from controller
to complete client authentication.
