1.4. Terminologies and acronyms

This section will define commonly used terms in this manual. These terms are related to Internetworking, and defined in regards to their use with Pro Series.

 MAC address

On a local area net work or ot her netwo rk, t he MAC (Medi a Acces s Control ) addre ss is the com puter' s unique hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)

It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique Identifier) number and 6-digit hardware identifier number. The Pro Series has the following MAC address template: 00-01-95-xx-xx-xx. The MAC address can be found on the bottom of the original package.

 Host

A user’s compute r c on n ec t e d t o t he network

Internet protocol specifications define "host" as any computer that has full two-way access to other computers on the Internet. A host will have a specific "local” or “host number" that, together with the network number, forms its unique IP address.



Session

A series of interactions between two communication end points that occur during the span of a single connection

Typically, one end point requests a connection with another specified end point. If that end point replies, agreeing to the connection, the end points take turns exchanging commands and data ("talking to each other"). The session begins when the connection is established at both ends and terminates when the connection is ended.



Client/Server

Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request.

A server is a computer program that provides services to other computer programs on one or many computers. The client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.

3. Network Configuration

3.1. IP Configuration

The Pro Series requires a valid IP address to operate within the user’s network environment. If the IP address is not readily available, contact the system administrator to obtain a valid IP address for the Pro Series. Please note that the Pro Series requires a unique IP address to connect to the user’s network.

The users may choose one of three Internet protocols in setting up the Pro Series IP address: i.e.,

• Static IP

•

The Pro Series is initially defaulted to STATIC mode, with a static IP address of 192.168.161.5. Table 3-1 shows the configuration parameters for all three IP configurations. Figure 3-1 shows the actual

web-based GUI to change the user’s IP configuration.

Figure 3-1 IP Configuration

3.1.1. Using a Static IP Address

When using a Static IP address, the user must manually specify all the configuration parameters associated with the IP address of the Pro Series. These include the IP address, the network subnet mask, the gateway computer and the domain name server computers. This section will look at each of these in more detail.

Note: The Pro Series will attempt to locate all this information every time it is turned on.

 IP address

A Static IP address acts as a “static” or permanent identification number. This number is assigned to a computer to act as its location address on the network. Computers use these IP addresses to identify and talk to each other on a network. Therefore, it is imperative that the selected IP address be both unique and valid in a network environment.

Note: 192.168.1.x will never be assigned by and ISP (Internet Service Provider). IP addresses using this form are considered private. Actual applicatio ns of the Pro Series may require access to publi c network, such as the Internet. If so, a valid public IP address must be assigned to the user’s computer. A public IP address is usually purchased or leased from a local ISP.

 Subnet mask

A subnet represents all the network hosts in one geographic location, such as a building or local area network (LAN). The Pro Series will use the subnet mask setting to verify the origin of all packets. If the desired TCP/IP host specified in the packet is in the same geographic location (on the local network segment) as defined by the subnet mask, the Pro Series will establish a direct connection. If the desired TCP/IP host specified in the packet is not identified as belonging on the local network segment, a connection is established through the given defa ult gateway.

 Default gateway

A gateway is a network point that acts as a portal to another network. This point is usually the computer or computers that control traffic within a network or a lo cal ISP (Internet s ervice provider). The Pro Series uses the IP address of the default gateway computer to communicate with hosts outside the local network environment. Refer to the network administrator for a valid gateway IP address.



Primary and Secondary DNS

The DNS (Domain Name System) server is used to locate and translate the correct IP address for a requested web site address. A domain name is the web address (i.e. www.yahoo.com) and is

usually easier to remember. The DNS server is the host that can translate such text-based domain names into the numeric IP addresses for a TCP/IP connection.

The IP address of the DNS server must be able to access the host site with the provided domain name. The Pro Series provides the ability to configure the required IP addresses of both the Primary and Secondary DNS servers addresses. (The secondary DNS server is specified for use when the primary DNS server is unavailable.)

3.1.2. Using DHCP

Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network administrators manage and automate the assignment of IP addresses centrally in an organization's network. DHCP allows the network administrator the ability to Provise and distribute IP addresses from a central point and automatically send a new IP address when a computer is plugged into a different network location.

When in static IP mode, the IP address must be entered manually at each computer. If a computer is moved to another network location, a new IP address must be assigned. DHCP allows all the parameters, including the IP address, subnet mask, gateway and DNS servers to be automatically configured when the IP address is assigned. DHCP uses a “lease” concept in assigning IP addresses to a computer. It limits the amount of time a given IP address will be valid for a computer. All the parameters required to assign an IP address are automatically configured on the DHCP server side, and each DHCP client computer receives this information when the IP address is provided at its bootup.

Each time the device is reset, the Pro Series broadcasts a DHCP request over the network. The reply generated by the DHCP server contains the IP address, as well as the subnet mask, gateway address, DNS servers and the “lease” time. The Pro Series immediately places this information in its memory. Once the “l ease” expires, the P ro Series will r equest a renewal of the “lease” t ime from the DHCP server. If the DHCP server approves the request for renewal, the Pro Series can continue to work with the current IP address. If the DHCP server denies the request for renewal, the Pro Series will start the procedure to request a new IP address from the DHCP server.

Note: While in DHCP mode, all network-related parameters for the Pro Series are to be configured automatically, including the DNS servers. If the DNS server is not automatically configured, the user may manually configure the settings by entering the primary and secondary DNS IP addresses. To force an automatic configuration of the DNS address, set the primary and secondary DNS IP addresses to 0.0.0.0 (recommended).

A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the network administrator. This means that the DHCP client, i.e. the Pro Series, receives a different IP

address each time it boots up. The IP address should be reserved on the DHCP server side to assure that the user always knows the newly assigned Pro Series address. In order to reserve the IP address in the DHCP network, the administrator needs the MAC address of the Pro Series found on the label sticker at the bottom of the Pro Series.

3.2. SNMP Configurations

The Pro Series has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1 and v2 protocols. Network managers like NMS or SNMP Browser can exchange information with Pro Series, as well as access required functionality.

SNMP protocols include GET, SET, GET–Next, and TRAPs. With these functions, a manager can be notified of significant events (TRAPs), query a device for more information (GET), and make changes to the device state (SET). SNMPv2 adds a GET–Bulk function for retrieving tables of information and security functions.

With the SNMP configuration panel, the user can configure MIB-II System objects, access control settings and TRAP receiver settings. The manager configured in this menu can perform both information exchange and action control. Figure 3-2 shows a SNMP configuration screen via a web interface.

Figure 3-2 SNMP Configuration

3.2.1. MIB-II System objects Configuration

MIB–II System objects configuration sets the System Contact, Name, Location, and Authenticationfailure traps used by the SNMP agent of the Pro Series. These settings provide the values used for the MIB-II sysName, sysContact, sysLocation, sysService and enableAuthenTrap.

Brief descr i ptions of each object are as fol l ows,

 sysContact: Identification of the contact person for the managed system (Pro Series), and a

description of how to contact the person.

 sysName: Name used to identify the system. By convention, this is the fully qualified domain

name of the node.

 sysLocation: The physical location of the system (e.g., Room 384, Operations Lab, etc.).  sysService(Read Only) : A series of values, separated by commas, that indicate the set of

services that the system provides. By default, Pro Series only supports an Application(7) service level.

 EnablePoweronTraps: Indicates whether the SNMP agent process is permitted to generate

power-on traps.

 EnableAuthenTrap: Indicates whether the SNMP agent process is permitted to generate

authentication-failure traps. The value of this object overrides any configuration information; as such, it provides a means whereby all authentication-failure traps may be disabled..

 EnableLoginTrap: Indicates whether the SNMP agent process is permitted to generate system

For more information about the MIBs and SNMP, see the RFCs 1066, 1067, 1098, 1317, 1318 and 1213.

3.2.2. Access Control Configuration

Access Control defines accessibility of managers to the Pro Series SNMP agent. Only the manager set in this menu can access Pro Series SNMP agent to exchange information and control actions. If there is no specified IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can access the Pro Series SNMP agent.

3.2.3. Tr ap Receiver Configuration

The Trap receiver defines managers, which can be notified of significant events(TRAP) from the Pro Series SNMP agent.

3.2.4. Management using SNMP

The Pro Series can be managed through the SNMP protocol using NMS (Network Management System) or SNM P Browser. Before using the NMS or SNMP Browser, the user must set the access control configuration properly so that the Pro Series permits host access where the NMS or SNMP Browser is executed. Figure 3-3 shows a screen shot of a typical SNMP browser with MIB-II OIDs of the Pro Series SNMP agent.

3.3. Dynamic DNS Configuration

When users connect the Pro Series to a DSL line or use a DHCP configuration, the IP address might be changed whenever it reconnects to the network. It can therefore be very difficult to post all related contacts for each new IP address. In addition, if the administrator only has access through the remote console, there is no way to know if an IP address has changed, or what the new IP address is.

A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By using the Dynamic DNS service, users can access the Pro Series through the hostname registered in the Dynamic DNS Server regardless of any IP address change.

By default, the Pro Series only supports Dynamic DNS service offered at Dynamic DNS Network Services, LLC (www.dyndns.org DNS service providers.

To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set
