Cisco Systems OL-7426-03 quick start About Cisco Wlan Solution Wired Connections

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.

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.

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.

About Cisco 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
