Ethernet or Token Ring Bridge xv
Welcome to the Ethernet or Token Ring Bridge
The Ethernet or Token Ring Bridge allows the connections of two or
more remote Ethernet or Token Ring LAN’s into a single virtual LAN.
Workstations on each of the remote LAN’s may communicate with each
other as though they were on the same physical LAN. The Ethernet or
Token Ring Bridge can also function as a Radio Access Point and pro-
vide transparent, wireless data communications between the wired LAN
(and/or within the Radio Network) and fixed, portable or mobile devices
equipped with a wireless adapter employing the same modulation.
Data Transparency and Protocols
The Ethernet or Token Ring Bridge transports data packets transparently
as they move through the Wireless Infrastructure.
The Bridge is also protocol independent for all packets, except those
either addressed specifically to the Bridge or sent as multicast address
packets.
Depending on the address, packets will be processed as follows:
n All packets, except those either addressed specifically to the Bridge
or sent as multicast address packets, will be processed without
examining the contents of the packet and without regard to the
protocol used.
n Packets addressed specifically to the Bridge will be examined by
looking at the protocol header. If the protocol is recognized, the
packet will be processed.
n Multicast address packets will also be examined by looking at the
protocol header, but will be processed whether the protocol is
recognized or not.
n If protocol filtering is enabled then the appropriate parts of the
packet will be examined.
Ethernet or Token Ring Compatibility
The Ethernet Bridge can attach directly to 10Base2 (Thinnet), 10Base5
(Thicknet) or 10BaseT (Twisted Pair) Ethernet LAN segments. These
segments must conform to IEEE 802.3 or Ethernet Blue Book specifica-
tions.
