Configuring Cisco Wireless LAN Controller Interfaces

As described in the 

 section, the Cisco 2000 Series Wireless LAN Controller 

has up to four physical ports, the Cisco 4100 Series Wireless LAN Controller has two redundant physical 
ports, and the Cisco 4400 Series Wireless LAN Controller has one (4402) or two (4404) pairs of 
redundant physical ports. This means that the Cisco 4100 Series Wireless LAN Controller can physically 
connect to one subnet, and the Cisco 2000 Series Wireless LAN Controller and Cisco 4400 Series 
Wireless LAN Controllers can physically connect to multiple subnets.
Each of the physical ports can have multiple Interfaces applied to it:

•

The 

 controls communications with network equipment for all physical 

ports in all cases. 
When the Cisco WLAN Solution is operated in Layer 2 Mode (see 

), the Management Interface also controls communications between the Cisco 

Wireless LAN Controller and Cisco 1000 Series Lightweight Access Points.
When the Cisco WLAN Solution is operated in Layer 3 Mode, the Management Interface no 
longer controls communications between the Cisco Wireless LAN Controller and Cisco 1000 
Series lightweight access points.

When the Cisco WLAN Solution is operated in Layer 3 Mode (see 

), the 

 controls all communications between the Cisco Wireless 

LAN Controller and Cisco 1000 Series Lightweight Access Points.

Each physical port can also have between one and 512
