Protocol Description
IP Multicast IP Multicast is an extension to the IP protocol. It
enables individual packets to be sent to multiple hosts
on the Internet, and is often used for handling e-mail
mailing lists and teleconferencing/videoconferencing.
RARP Reverse Address Resolution Protocol. This IP
protocol provides a way for computers to determine
their own IP addresses when they only know their
hardware address (i.e., MAC addresses). Certain
types of computers, such as diskless workstations,
must use RARP to determine their IP address before
communicating with other network devices.
AppleTalk® A networking protocol used in for Apple Macintosh®
networks.
NetBEUI NetBIOS Enhanced User Interface. On many LAN
operating systems, the NetBEUI protocol provides the
method by which computers identify themselves to
and communicate with each other.
IPX Internetwork Packet Exchange. A networking protocol
used on Novell Netware
®
-based LANs.
BPDU Bridge Protocol Data Unit. BPDUs are data
messages that are exchanged across the switches
between LANs that are connected by a bridge. BPDU
packets contain information on ports, addresses,
priorities, and costs, and are exchanged across
bridges to detect and eliminate loops in a network.
ARP Address Resolution Protocol. Computers on a LAN
use ARP to learn the hardware addresses (i.e., MAC
addresses) of other computers when they know only
their IP addresses.
IPV6 Multicast IP Multicasting under IP Protocol version 6. See IP
Multicast above.
802.1.Q This IEEE specification defines a protocol for virtual
LANs on Ethernet networks. A virtual LAN is a group
of PCs that function as a local area network, even
though the PCs may not be physically connected.
They are commonly used to facilitate administration of
large networks.

function as expected, if you want the changes to be permanent,
follow the instructions on page 46 to commit them.
