Features and Functional Overview
2-8 6710 Access Point User’s Guide
The physical connections are on the bottom panel of the
access point. The desired Ethernet medium is selectable
through the device configuration menus. Section 3,
“Installation,” has more information about connecting the
access point to Ethernet media. Section 4, “Configuration,”
describes how to set the medium through the configuration
menus.
Ethernet Port Filters
The Ethernet port can be configured to support a variety of
preconfigured and custom input filters. Access points are
commonly installed on LANs that carry traffic for wired and
wireless devices. Setting filters prevents unnecessary
traffic from the wired LAN from being forwarded onto the
wireless medium. This is important because common
wireless technologies operate at data rates below Ethernet
speeds.
Normally, filters are set to
pass traffic known to be (or
likely to be) destined for wireless stations, and drop traffic
not destined for stations requiring wireless connectivity.
Filtering occurs in the Ethernet driver software that
controls low level operation of the Ethernet ports,
minimizing involvement of other functions when
unnecessary frames are received. In most installations, the
predefined filters are used. The default access point
configuration sets no filters. Filter setup is discussed in
more detail in Section 4, “Configuration.”
Filtering and flooding control (described on page 2-6) are
complimentary but have different functions. Filters allow
frames to be eliminated based upon content of the frame,
usually the network protocol header fields within the frame.
For example, filters can be set to eliminate some or all IP
traffic or Novell IPX traffic.
