AP Manager Internet
- Used for Layer 3 communications between WLC and lightweught AP after the access points have joined the controller.
- Used as the tunnel source/destination for communication between WLC and AP.
Management Interface
- In-band management of the controller. Use for access to the controller GUI.
- Used by AP’s to discover the controller. Acts like an AP manager interface by default.
- Inter-controller communications. Mobility groups exchange information using the management interface
- Is the only consistently pingable in-band interface IP address on the controller.
Virtual Interface
- Used to support mobility management
- Act as DHCP relay and DNS gateway
- Uses as the source of certificates when Layer 3 Web authorisation is enabled.
- For embedded L3 security such as guest web authentication and VPN termination.
- Acts as the DHCO server placeholder for wireless clients that obtain their IP address from a DHCP server.
- Serves as the redirect address for the web authentication login page.
Dynamic Interface
- Also known as VLAN interfaces and are created by users. Designed to be analogous to VLANs for wireless LAN clients.
- Mapped onto WLANs
Service Interface
- Out of band management and can also be used for system recovery and maintenance purposes.
- Statically mapped by the system to the service port
- This is the only port that will be active when the controller is in boot mode
- Default gateway cannot be assigned to the service port interface. Instead, static routes can be defined through the controller for remote network access to the service port.
