Cisco Wireless LAN Solution Product Guide
OL-7955-01
Chapter 1 Overview
Cisco WLAN Solution Wireless LANs
The Cisco 4100 Series Wireless LAN Controller connects to the network using one or two
fiber-optic Gigabit Ethernet cables: two redundant Gigabit Ethernet connections to bypass single
network failures. At any given time one of the Cisco 4100 Series Wireless LAN Controller Gigabit
Ethernet 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 Gigabit Ethernet cables, and the 4404 Cisco 4400 Series Wireless LAN Controller
connects to the network using one through four fiber-optic Gigabit Ethernet cables: two redundant
Gigabit Ethernet connections to bypass single network failures. At any given time one of each pair
of Cisco 4400 Series Wireless LAN Controller Gigabit Ethernet 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 Ethernet (PoE)
capability. This power distribution plan can be used to reduce the cost of individual AP power
supplies and related cabling.
Cisco WLAN Solution Wireless LANs
The Cisco Wireless LAN Solution can control up to 16 Wireless LANs for lightweight access points.
Each wireless LAN has a separate wireless LAN ID (1 through 16), a separate wireless LAN SSID
(wireless LAN name), and can be assigned unique security policies.
The Cisco 1000 series lightweight access points broadcast all active Cisco WLAN Solution wireless
LAN SSIDs and enforce the policies defined for each wireless LAN.
Note Cisco recommends that you assign one set of VLANs for wireless LANs and a different set of VLANs
for Management Interfaces to ensure that controllers properly route VLAN traffic.
If management over wireless is enabled across Cisco Wireless LAN Solution, the Cisco Wireless LAN
Solution operator can manage the System across the enabled wireless LAN using CLI and Telnet,
http/https, and SNMP.
To configure the Cisco WLAN Solution wireless LANs, refer to Chapter 5, “Configuring Wireless
LANs.”
Access Control Lists
The operating system allows you to define up to 64 Access Control Lists (ACLs), similar to standard
firewall Access Control Lists. Each ACL can have up to 64 Rules (filters).
Operators can use ACLs to control client access to multiple VPN servers within a given wireless LAN.
If all the clients on a wireless LAN must access a single VPN server, use the IPSec/VPN Gateway
Passthrough setting, described in the “Security Overview” section on page 3-2.
After they are defined, the ACLs can be applied to the management interface, the AP-Manager interface,
or any of the operator-defined interfaces.
Refer to Access Control Lists > New in the Web User Interface Online Help for instructions on
configuring Access Control Lists.
