lightweight access points as Rogue Access Points. Likewise, the Cisco Wireless LAN Controllers in the
XYZ Controller Mobility Group do not recognize or communicate with the Cisco Wireless LAN Controllers
in the ABC Controller Mobility Group. This feature ensures Controller Mobility Group isolation across the
network.

The Controller Mobility Group feature can also be used to limit roaming between different floors, build-
ings, or campuses in the same enterprise by assigning different Controller Mobility Group names to
different Cisco Wireless LAN Controllers within the same wireless network.
If enabled, Radio Resource Management (RRM)
operation is constrained within each Controller Mobility
Group.
CAUTION: Cisco recommends that you assign one set of VLANs for WLANs and a
different set of VLANs for Management Interfaces to ensure that Cisco Wireless LAN
Controllers properly route VLAN traffic.
CAUTION: The Cisco SWAN does not support simultaneous inter-switch and
inter-subnet roaming. Either install all the Controller Mobility Group members in the
same subnet or install all the Controller Mobility Group members in different subnets.
Note: Because the Cisco Wireless LAN Controllers talk to each other when they are in
the same Controller Mobility Group, Cisco recommends that operators do not add
physically separated Cisco Wireless LAN Controllers to the same static Controller
Mobility Group to avoid unnecessary traffic on the network.
