This MIB is intended to be implemented on all those devices operating as Central Controllers (CC) that terminate the Light Weight Access Point Protocol tunnel from Light-weight LWAPP Access Points. This MIB provides configuration and status information about the ACLs on the controller. Particularly this mib covers the CPU ACLs for the wireless controllers. Traffic to the controller CPU comes from the NPU (Network Processing Unit). Using CPU ACLs, the user can place restrictions on type of traffic reaching the CPU of the controller from the NPU. CPU ACLs introduce an ACL for the traffic to the CPU of controller. With this ACL the type of packets reaching the CPU can be controlled. The mode of operation is as follows. The administrator designates one ACL for the traffic to the CPU. The ACL kicks in for packets from the NPU to the CPU. Each ACL is an ordered set of rules. If a rule matches then action for that rule is applied to the packet. The decision to send or drop the packet is taken based on the action parameter of the ACL. There will be no ACL for the packets from the CPU to the NPU. GLOSSARY Access Control List ( ACL ) A list of rules used to restrict the traffic reaching an interface or the CPU. Each ACL is an ordered set of rules and actions. If a rule matches then the action for that rule is applied to the packet. Access Point ( AP ) An entity that contains an 802.11 medium access control ( MAC ) and physical layer ( PHY ) interface and provides acess to the distribution services via the wireless medium for associated clients. CPU ACL ( CPU ACL ) The ACL applied to the CPU. This controls the type of traffic reaching the CPU of the controller. Network Processing Unit ( NPU ) This entity is responsible for forwarding traffic to the CPU. The only exceptions are data coming thorugh the console port and the Service port i.e. these communicate directly with the CPU and not via the NPU. Light Weight Access Point Protocol ( LWAPP ) This is a generic protocol that defines the communciation between the Access Points and the Central Controller. Cryptographically Generated Addresses (CGA) Cryptographically Generated Addresses (CGAs) are IPv6 addresses, which allow for a secure association of an IPv6 address, the CGA, with a public key.
