Introduction

Transmitted ARP request packets echo back to other MUs.

The AP removes from its database the destination or interface information that is not used for a specified time. The AP refreshes its database when it transmits or receives data from these destinations and interfaces.

Filtering and Access Control

The AP provides facilities to limit the MUs that associate with it and the data packets that can forward through it. Filters provide network security and improve performance by eliminating broadcast/multicast packets from the radio network.

The ACL (Access Control List) contains MAC addresses for MUs allowed to associate with the AP. This provides security by preventing unauthorized access.

The AP uses a disallowed address list of destinations. This feature prevents the AP from communicating with specified destinations. This can include network devices that do not require communication with the AP or its MUs.

Depending on the setting, the AP can keep a list of frame types that it forwards or discards. The Type Filtering option prevents specific frames (indicated by the 16-bit DIX Ethernet Type field) from being processed by the AP. These include certain broadcast frames from devices that consume bandwidth but are unnecessary to the wireless LAN. Filtering out frames can also improve performance.

1.3.2Auto Fallback to Wireless Mode

The AP supports an Auto Fallback to wireless mode when the hardware Ethernet connection fails or becomes broken. The Auto Fallback function operates only with an AP in WLAP mode and connected to the Ethernet network. The AP resets itself and during initialization attempts to associate with any other WLAP in the network.
