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. 
 
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.
