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
Internet work 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.
To block a protocol, click the appropriate check box, and click
. After you have verified that the device continues to
function as expected, click the Admin tab, click
Commit & Reboot
in the task bar, and then click
to save your changes to
permanent memory.
