Controller Platforms
Cisco 2000 and 2100 Series Controllers
The Cisco 2000 and 2100 Series Wireless LAN Controllers work in conjunction with Cisco lightweight
access points and the Cisco Wireless Control System (WCS) to provide system-wide wireless LAN
functions. Each 2000 and 2100 series controller controls up to six lightweight access points for
multi-controller architectures typical of enterprise branch deployments. It may also be used for single
controller deployments for small and medium-sized environments.
Caution Do not connect a power-over-Ethernet (PoE) cable to the controller’s console port. Doing so may damage
the controller.
Note Wait at least 20 seconds before reconnecting an access point to the controller. Otherwise, the controller
may fail to detect the device.
Features Not Supported
These hardware features are not supported on 2000 and 2100 series controllers:
• Power over Ethernet (PoE) [2000 series controllers only]
Note Ports 7 and 8 on 2100 series controllers are PoE ports.
• Service port (separate out-of-band management 10/100-Mbps Ethernet interface)
These software features are not supported on 2000 and 2100 series controllers:
• VPN termination (such as IPSec and L2TP)
• Termination of guest controller tunnels (origination of guest controller tunnels is supported)
• External web authentication web server list
• Layer 2 LWAPP
• Spanning tree
• Port mirroring
• Cranite
• Fortress
• AppleTalk
• QoS per-user bandwidth contracts
• IPv6 pass-through
• Link aggregation (LAG)
