Controller teaming
Key concepts
8-3
Redundancy and failover support
The team provides for service redundancy in case of failure. If one of the controllers in a
team becomes inoperative (due to network problems, hardware failure, etc.), its APs will
automatically migrate to another controller in the team allowing for continuation of services.
For this to work, sufficient capacity must be available on the remaining controllers in the
team to support the APs from the inoperative controller. For more information see, Failover
on page 8-22.
Important When a controller becomes inoperative and failover occurs, all services provided by the
controller are temporarily interrupted. Once failover is complete and services return, users
that were connected to an access-controlled VSC must login again.
Scalability
Controller teaming enables you to scale up your wireless network as your needs increase.
Simply add additional APs, controllers, and licenses to meet the required demand. Up to 800
APs are supported per team in its maximum configuration (four controllers x 200 APs per
controller plus one additional controller for backup/redundancy).
Deployment considerations
Controllers/APs
 Teaming is only supported on the MSM760 and MSM765 controllers.
 A controller can only be a member of one team at a time.
 Controllers must be the same model type as the team manager.
 Up to five controllers can be combined into a team supporting up to 800 APs (four
controllers x 200 APs per controller + one controller reserved for backup purposes).
Licensing
 MSM760 Controllers must have the Premium license installed to support teaming.
(Licenses must be installed individually on each controller that is part of the team.)
MSM765 Controllers come with this license preinstalled.
 You must install enough AP licenses to support all the APs you intend to manage with the
team. When teaming is enabled, AP licenses are pooled across all controllers. See
Failover on page 8-22 for more information on how AP licenses are managed.
Networking
 The LAN and Internet ports on all team members must be configured with the same
networking options (subnet, VLAN, etc.). For example, if you configure the LAN port on
the manager to be on the 192.168.1.0 subnet, then all other team members must have their
LAN ports on the same subnet. The LAN port and Internet port cannot be on the same
subnet.
