About the Management Interface
The logical Management Interface controls Layer 2 communications between Cisco Wireless LAN Controllers and Cisco 1000 Series lightweight access points.
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 Management Interface is assigned to one physical port (Cisco WLAN Solution Wired Connections), through which it communicates with other network devices and other access points. However, the Management Interface can also communicate through all other physical ports except the Service Port as follows:
•Sends messages through the Layer 2 network to autodiscover and communicate with other Cisco Wireless LAN Controllers through all physical ports except the Service Port.
•Listens across the Layer 2 network for 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.
Note: 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 Management 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 Cisco Wireless LAN Controller Failover Protection section for more information.
Note: The Management Interface cannot be assigned to the dedicated Cisco Wireless LAN Controller Service Port.
The Management Interface uses the
•VLAN assignment.
•Fixed IP Address, IP netmask, and default gateway.
•Physical port assignment.
•Primary and Secondary DHCP Servers.
•Access Control List, if required.
