MSM7xx Controllers Configuration Guide v6.4.0

unauthenticated wireless users once they successfully connect to the wireless network. Access to
the protected network is restricted by the controller and typically requires that users be authenticated
by the controller before they gain access.
When teaming is enabled, a couple of important factors come into play which impact how guest
access can be configured:
• Use of an external DHCP server is mandatory: Since the internal DHCP server is not supported
on a controller team, and client traffic is always sent to the team using the client data tunnel,
this forces the use of an external DHCP server and implies that the controller team be configured
for DHCP relay.
• Multiple gateways are introduced: All teamed controllers are required to operate on the same
subnets, which means that there is no longer one choice of gateway to allow proper routing
of traffic from client to destination and back.
The following diagram presents an overview of how guest access can be setup with a controller
team.
