3.4 SNMP
SNMP - Simple Network Management Protocol, is used to communicate management
information (MIB or Management Information Base) between the network management
stations (e.g a management software running in your PC) and the agents in the network
elements (e.g your Router).
SNMP communities (used in this case like passwords) can be set with the following table.
Any number of community strings can be set up, each of which can be set to allow either
read-write or read-only access. It also can be usable either from any IP address or only
from a configured management IP address (authorized IP).
i) Click the SNMP tab.
To add an access right or read, enter the required information and click Add.
SNMP Access Right (Write) To have read and write access to SNMP
MIB of your Router.
SNMP Access Right (Read) To have read access only, to SNMP MIB
of your Router.
38
Software Manual
Community A community name that corresponds to
the password that you need to provide
when accessing the Router from any

Glossary
ADSL
ADSL, Asymmetric Digital Subscriber Line, is a broadband communication technology
designed for use on regular phone lines. It has the ability to move data over the phone lines
at speeds up to 140 times faster than the analog modem available today.
CHAP
CHAP, Challenge Handshake Authentication Protocol, is one of the two PPP authentication
protocols, with PAP the other one. Authentication protocol requests information to verify
a valid user. CHAP is a stronger authentication method because it uses encryption and may
repeatedly request verification of the identity of the user any time after the link is established.
Client
Devices and software that request information.
Community
Community names are passwords which are also used by other applications, such as Telnet.
DHCP
DHCP stands for Dynamic Host Configuration Protocol. Every computer on a TCP/IP
network must be given a unique computer name and IP address. DHCP is an industry
standard protocol that specifies methods for dynamic configuration of computers on TCP/
IP networks. It allows centralized configuration of all workstations TCP/IP protocol and IP
address allocation from the server.
After you activate the DHCP server, whenever a network client select dynamic DHCP
configuration option in configuring TCP/IP protocol and IP address, the task of allocation of
IP address will be done dynamically and automatically by the DHCP Server.
DNS
DNS stands for Domain Name Server. The main purpose for DNS is to map host names into
Internet addresses (so call IP address), or vice versa.
If the first DNS server cannot process the translation request, it queries an upstream DSN
server, and another one, and so on, until the correct IP address is returned or no corresponding
address for the request can be found.
DNS Relay
A DNS Relay is a software entity that appears to behave as a DNS server from the point
of view of a DNS resolver, and vice-versa. It forwards DNS queries from a DNS resolver
to a DNS server, and returns responses from the DNS server back to the original DNS
resolver.

Software Manual
Gateway IP
The IP address of a machine (other Router or server) that will resolve any unknown
destination IP address requested by Clients.
Host
On the Internet, the term host means any computer that has full two-way access to other
computers on the Internet. A host has a specific local or host number that, together with
the network number, forms its unique IP address.
In other contexts, the term generally means a device or program that provides services to
some smaller or less capable device or program.
IP
IP, Internet Protocol, is the method or protocol by which data is sent from one computer to
another on the Internet.
IP Address
A 32-bit binary number that is usually represented as a 4 decimal numbers separated by
dots ".". Each IP address uniquely identifies each host on the Internet.
LAN
Local Area Network. A computer network limited to the immediate area, usually the same
building or floor of a building.
LLC SNAP
LLC SNAP is one of two encapsulation methods used in telecommunication, with VC MUX
the other one. Encapsulation is the inclusion of one data structure within another structure
so that the first data structure is hidden for the time being.
NAT
NAT, Network Address Translation, is designed for IP address simplification and conservation,
as it enables private IP internetworks that use non-registered IP addresses to connect to the
Internet. NAT operates on a Router, usually connecting two networks together, and
translates the private (not globally unique) addresses in the internal network into legal
addresses before packets are forwarded onto another network. NAT has the dual functionality
of security and address conservation, and is typically implemented in remote access
environments.
NAT Inbound
This command enables the user to list or to set up a series of rules for incoming traffic when
NAT is enabled. By default all incoming packets, other that packets arriving in response
to outgoing traffic, will be rejected.
43
Software Manual
Network
Any time you connect 2 or more computers together so that they can share resources, you
have a computer network.
Packet
Generic term for a bundle of data, organized in a specific way for transmission over a
network. Packet and datagram are similar in meaning. A protocol similar to TCP, the
User Datagram Protocol (UDP) uses the term datagram.
PAP
PAP, Password Authentication Protocol, is one of the two PPP authentication protocols, with
CHAP the other one. An authentication protocol requests information to verify a valid user.
PAP requests the user's name and password for verification.
Password
A string of characters assigned to you to gain access to a locked system.
PPP
PPP stands for Point to Point Protocol. It normally means: regular phone line, ISDN, xDSL
connections that require their respective point to point modems.
The protocol used to carry TCP/IP traffic to the ISP across modem and ISDN links. PPP
incorporates authentication (username/password checking).
PPPoATM (PPP over ATM)
PPP over ATM - RFC 2364
PPP over ATM (PPPoATM) is the most elegant and simple implementation that provides
encapsulation over a routed ADSL connection.
®
Microsoft provides a PPP over ATM stack in Windows
and Windows
modems such as internal cards and USB devices.
®
2000 and this provides an almost ideal implementation for passive ADSL
98 Second Edition, Windows® Me
PPP
PPPoE (PPP over Ethernet)
PPP over Ethernet (PPPoE) is used in some existing ADSL services. It requires a custom
driver in the users PC, similar manner to Dial-Up Networking. In other words, you will
be dependent on the PPP over Ethernet (PPPoE) client being available for your operating
system platform.
Protocol
In information technology, a protocol is a special set of rules, procedures and conventions
that two end points in a telecommunication connection use when they communicate.

Software Manual
PVC
PVC, Permanent Virtual Circuit, is an ATM virtual circuit established on top of your ADSL
connection from your Router to your ADSL Service Provider. The call set-up and tear-down
are not visible, which creates the feeling of having a dedicated connection to the Internet.
RFC 2684 (RFC 1483) Bridged or Ethernet Framing
Encapsulation of bridged network data, such as Ethernet frames, in ATM Adaptation Layer
5 (AAL5) Protocol Data Units (PDU).
RFC 2684 (RFC 1483) Routed or IP Framing
Encapsulation and Transmission of routed network data, such as IP datagrams, over ATM
Adaptation Layer 5 (AAL5) Protocol Data Units (PDU).
RFC 2225 (RFC 1577)
Transmission of IP datagrams and ATM Address Resolution Protocol (ATMARP) requests and
replies over ATM Adaptation Layer 5 (AAL5).
RFC 2516
Creation and maintenance of a Point-to-Point-Protocol (PPP) session over an Ethernet link.
RFC 2364
Creation and maintenance of a Point-to-Point-Protocol (PPP) session over an ATM link.
Router
A device that handles the connection between 2 or more networks. Routers spend all their
time looking at the destination addresses of the packets passing through them and deciding
which route to send them on.
SNMP
SNMP stands for Simple Network Management Protocol. SNMP manages the list of SNMP
community names (also used as passwords by other applications, such as telnet) and the
list of SNMP trap destinations.
Static Route
Route that is explicitly configured and entered into the routing table. Static routes take
precedence over routes chosen by dynamic routing protocols.
Subnet Mask
32-bit address mask used in IP to indicate the bits of an IP address that are being used
for the subnet address. Sometimes referred to simply as mask.
45
Software Manual
TCP
TCP, Transmission Control Protocol, is a transport protocol used along with the Internet
Protocol (IP) to send data in the form of message units between computers over the Internet.
While IP takes care of handling the actual delivery of the data, TCP takes care of keeping
track of the packets and provide error recovery mechanism.
TCP/IP
See TCP.
Telnet
Telnet is the way you can access a remote computer, provided you have given access to it.
More technically, Telnet is a user command and an underlying TCP/IP protocol for accessing
remote computers. With Telnet, you log on as a regular user with whatever privileges you
may have been granted to the specific application and data on that computer.
Transparent Bridge
Joining two or more bridged network segments (such as Ethernet) running on different
physical media.
UDP
User Datagram Protocol. UDP is a stateless protocol in that it makes no provision for
acknowledgement of packets received.
VPI/VCI
The ATM Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) uniquely identify
a virtual circuit on an ATM link, such as PVC. An ATM switch (or other device incorporating
ATM switching capability like a DSLAM) can be configured to take data from one VPI/VCI
on an incoming link and map it to another VPI/VCI on an outgoing link. This configuration
defines the route through the ATM switch. Note that this means that a particular data
connection may be given many different VPI/VCI addresses as it passes through the
network.
WAN
Wide Area Network. Any Internet or network that covers an area larger than a single
building or campus.
