The Cisco WLAN Solution Mobility Group feature can also be used to limit roaming between different
floors, buildings, or campuses in the same enterprise by assigning different 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 Cisco WLAN
Solution Mobility Group.
About Cisco WLAN Solution Wired ConnectionsCisco WLAN Solution Wired Connections
The Cisco WLAN Solution components communicate with each other using industry-standard Ethernet
cables and connectors. The following paragraphs contain details of the Cisco WLAN Solution wired
connections.
• The Cisco 2000 Series Wireless LAN Controller connects to the network using between one and
four 10/100BASE-T Ethernet cables.
• The Cisco 4100 Series Wireless LAN Controller connects to the network using one or two
fiber-optic GigE cables: two redundant GigE connections to bypass single network failures. At
any given time one of the Cisco 4100 Series Wireless LAN Controller GigE connections is active
and the other is passive. Upon a network failure, the active connection becomes passive, and
the passive connection becomes active.
• The 4402 Cisco 4400 Series Wireless LAN Controller connects to the network using one or two
two fiber-optic GigE cables, and the 4404 Cisco 4400 Series Wireless LAN Controller connects to
the network using one through four fiber-optic GigE cables: two redundant GigE connections to
bypass single network failures. At any given time one of each pair of Cisco 4400 Series Wireless
LAN Controller GigE connections is active and the other is passive. Upon a network failure, the
active connection becomes passive, and the passive connection becomes active.
• Cisco 1000 Series lightweight access points connects to the network using 10/100BASE-T
Ethernet cables. The standard CAT-5 cable can also be used to conduct power for the Cisco
1000 Series lightweight access points from a network device equipped with Power Over
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.
Note: Because the Cisco Wireless LAN Controllers talk to each other when they are in
the same mobility group, Cisco WLAN Solution recommends that operators do not
add physically-separated Cisco Wireless LAN Controllers to the same static mobility
group to avoid unnecessary traffic on the network.
