Ports and Interfaces

A port is a physical entity, two types of ports: distribution system ports and a service port.

A distribution system port connects the controller to a neighbor switch and serves as the data path between these two devices.




The service port is controlled by the service-port interface and is reserved for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. Use of the service port is optional.




An interface is a logical entity on the controller.
  • Management interface (static and configured at setup time; mandatory)
  • AP-manager interface (static and configured at setup time; mandatory)   
Note You are not required to configure an AP-manager interface on Cisco 5500 Series Controllers.
 
  • Virtual interface (static and configured at setup time; mandatory)
  • Service-port interface (static and configured at setup time; optional)
  • Dynamic interface (user-defined)
The management interface is the default interface for in-band management of the controller and connectivity to enterprise services such as AAA servers. It is also used for communications between the controller and access points

For CAPWAP, the controller requires one management interface to control all inter-controller communications and one AP-manager interface to control all controller-to-access point communications,

A controller has one or more AP-manager interfaces, which are used for all Layer 3 communications between the controller and lightweight access points after the access points have joined the controller. The AP-manager IP address is used as the tunnel source for CAPWAP packets from the controller to the access point and as the destination for CAPWAP packets from the access point to the controller.

The virtual interface is used to support mobility management, Dynamic Host Configuration Protocol (DHCP) relay, and embedded Layer 3 security such as guest web authentication and VPN termination. It also maintains the DNS gateway host name used by Layer 3 security and mobility managers to verify the source of certificates when Layer 3 web authorization is enabled.

Dynamic interfaces, also known as VLAN interfaces, are created by users and designed to be analogous to VLANs for wireless LAN clients





DHCP

DHCP proxy mode  -  DHCP helper function

DHCP bridging mode - Transparent in DHCP Transaction.
