AP-Manager Interface

The logical AP-Manager Interface controls Layer 3 communications between Cisco Wireless LAN 
Controller and Cisco 1000 Series lightweight access points. 
The AP-Manager Interface is assigned to one physical port (

and can be on the same subnet and physical port as the 

Interface can communicate through any physical port except the 

 as follows:

•

Sends Layer 3 messages through the network to autodiscover and communicate with other 
Cisco Wireless LAN Controllers.

•

Listens across the network for Layer 3 Cisco 1000 Series lightweight access point LWAPP polling 
messages to autodiscover, associate with, and communicate with as many Cisco 1000 Series 
lightweight access points as it can.

The AP-Manager Interface must be configured for the following:

•

VLAN assignment.

•

Fixed IP Address (must be different than the Management Interface IP address, but must be on 
the same subnet as the Management Interface), IP netmask, and default gateway.

•

Physical port assignment.

•

Primary and Secondary DHCP Servers.

•

Access Control List, if required.

Refer to the 

 section for configuration instructions.

Operator-Defined Interfaces

Each Cisco Wireless LAN Controller can support up to 512 Operator-Defined Interfaces. Each Oper-
ator-Defined Interface controls VLAN and other communications between Cisco Wireless LAN 
Controllers and all other network devices connected to an individual physical port. Between one and 
512 Operator-Defined Interfaces can be assigned to 

, physical 

, the Layer 2 

, and the Layer 3 

.

 Should a Cisco Wireless LAN Controller fail, its dropped Cisco 1000 Series 

lightweight access points poll the network for another Cisco Wireless LAN Controller. 
When an online Cisco Wireless LAN Controller has any remaining Cisco 1000 Series 
lightweight access point ports, the AP-Manager Interface listens to the network for 
Cisco 1000 Series lightweight access point polling messages to autodiscover, 
associate with, and communicate with as many Cisco 1000 Series lightweight access 
points as it can. Refer to the 

 section 

for more information.

 The AP-Manager Interface cannot be assigned to the dedicated Cisco Wireless 

 Operator-Defined Interfaces cannot be assigned to the dedicated Cisco 

Wireless LAN Controller 

 Operator-Defined Interface names cannot have spaces in them. If an 

Operator-Defined Interface name contains a space, you may not be able to edit its
