Tsunami MP.11and MP.11a Installation and Management 
Glossary 
ARP
 
DHCP Relay Agent
 
The Address Resolution Protocol (ARP) is intended 
to find the MAC address belonging to an IP address. 
A feature of the MP.11/a that intercepts DHCP 
requests from clients and forwards them to a DHCP 
server. For the client, the DHCP Relay Agent of the 
MP.11/a functions like a DHCP server. This enables 
DHCP requests to pass router boundaries; for 
example, it is not required to have a DHCP server on 
every IP subnet. 
Authentication method
 
The process the MP.11/a uses to decide whether a 
station that wants to register is allowed or not. 
IEEE 802.11 specifies two forms of authentication: 
open system and shared key; WORP only supports 
shared key because of security constraints. 
Domain Name Server (DNS)
 
A domain name server is an Internet service that 
translates domain names into IP addresses. For 
example, www.ietf.org will be translated in 
4.17.168.6. 
Authentication server “Shared Secret”
 
This is a kind of password shared between the 
MP.11/a and the RADIUS authentication server. This 
password is used to encrypt important data 
exchanged between the MP.11/a and the RADIUS 
server 
Download
 
Downloading a file means copying a file from a 
remote server to a device or host. In case of the 
MP.11/a downloading means transferring a file from 
a TFTP server to the MP.11/a. 
Authentication server authentication port
 
This is a UDP port number (default is 1812), which is 
used to connect to the authentication server for 
obtaining authentication information. 
Downstream
 
Downstream means a data stream from the central 
part of the network to the end user. See also 
upstream
. 
Backbone
 
The central part of a network; the backbone network 
connects all remote and sub networks to each other 
and to the central infrastructure (such as the mail 
server, Internet gateway, and so on). 
Dynamic Host Configuration Protocol
 
Dynamic Host Configuration Protocol (DHCP) is a 
method to dynamically assign IP addresses. If DHCP 
is enabled, the device or computer will broadcast a 
request that will be answered by a DHCP Server. 
Base
 
If an interface is running in Outdoor mode (WORP), it 
is either a base or a satellite interface. A base 
interface controls the communication on the channel 
and is located in the central part of the network cell. 
Multiple satellites can connect to one base; two 
bases cannot communicate with each other.  
Encryption
 
Encryption is a means of coding data with a key 
before sending it across a network. The same key 
must be used to decode the information at the 
receiver. This way prevents unauthorized access to 
the data that is send across the network. 
Broadcast Storm
 
A broadcast storm is a large series of broadcast 
packets (most often caused by wrong network 
configuration) that severely impact the network 
performance. 
Ethernet
 
Ethernet is the most widely installed Local Area 
Network (LAN) technology. The MP.11/a supports 
both 10 and 100 Mbps and half and full duplex. 
Client IP Address Pool
 
This a pool of IP addresses from which the MP.11/a 
can assign IP addresses to clients, which perform a 
DHCP Request. 
Gateway
 
A gateway is network device that connects multiple 
(IP) networks to each other. A gateway can perform 
protocol conversion.    
Configuration Files
 
A configuration file contains the MP.11/a 
configuration details. Configuration items include 
among others the IP address and other network-
specific values. Configuration files may be uploaded 
to a TFTP server for backup and downloaded into the 
MP.11/a for restoring the configuration. 
Group
 
A group is logical collection of network parameters. 
For example, the System Group is composed of 
several parameters and tables giving system 
information of the MP.11/a. All items for a group are 
grouped under one tab of the Web Interface and start 
with the same prefix for the command line interface.
