C-1 Glossary x CHAPTER 1 INTRODUCTION Congratulations on your purchase of the Barricade Wireless Broadband Router with built-in ADSL Modem (SMC7404WBRA). We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, this Router provides a convenient and powerful solution. About the Barricade The Barricade provides Internet access to multiple users by sharing a single-user account. Support is provided for both wired and wireless devices. New technology provides wireless security via WEP (Wired Equivalent Privacy) encryption and MAC address filtering. It is simple to configure and can be up and running in minutes. Features Internet connection via an RJ-11 WAN port. Local network connection via four 10/100 Mbps Ethernet ports. On-board IEEE 802.11b 11 Mbps wireless network adapter. DHCP for dynamic IP configuration, and DNS for domain name mapping. Firewall with Stateful Packet Inspection, client privileges, intrusion detection, and NAT. 1-1 INTRODUCTION NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as Web, FTP, e-mail, and Telnet). VPN pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP). User-definable application sensing tunnel supports applications requiring multiple connections. Easy setup through a Web browser on any operating system that supports TCP/IP. Compatible with all popular Internet applications. Applications Many advanced networking features are provided by the Barricade:

Wireless and Wired LAN The Barricade provides connectivity to wired 10/100 Mbps devices, and wireless IEEE 802.11b compatible devices, making it easy to create a network in small offices or homes. Internet Access This device supports Internet access through an ADSL connection. Since many ADSL providers use PPPoE or PPPoA to establish communications with end users, the Barricade includes built-in clients for these protocols, eliminating the need to install these services on your computer. Shared IP Address The Barricade provides Internet access for up to 253 users via a single shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time. 1-2 APPLICATIONS Virtual Server If you have a fixed IP address, you can set the Barricade to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the Barricade can route the request to the appropriate server (at another internal IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network. DMZ Host Support Allows a networked computer to be fully exposed to the Internet. This function is used when NAT and firewall security prevent an Internet application from functioning correctly. Security The Barricade supports security features that deny Internet access to specified users, or filter all requests for specific services that administrator does not want to serve. The Barricades firewall also blocks common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. WEP

(Wired Equivalent Privacy), SSID, and MAC filtering provide security over the wireless network. 1-3 INTRODUCTION Virtual Private Network (VPN) The Barricade supports three of the most commonly used VPN protocols PPTP, L2TP, and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, then these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally shared data network). The VPN protocols supported by the Barricade are briefly described below. Point-to-Point Tunneling Protocol Provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs. L2TP merges the best features of PPTP and L2F Like PPTP, L2TP requires that the ISPs routers support the protocol. IP Security Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication. 1-4 CHAPTER 2 INSTALLATION Before installing the Barricade Broadband Router with built-in ADSL Modem, verify that you have all the items listed under Package Contents.

Specify the end IP address of the DHCP pool. If your network uses a domain name, enter it here. otherwise leave this field blank Remember to configure your client PCs for dynamic address allocation.

(See Configuring Client PC on page 3-1 for details.) 4-24

WIRELESS Wireless The Barricade also operates as a wireless-to-wired bridge, allowing wireless computers to access resources available on the wired LAN, and to access the Internet. To configure the Barricade as a wireless access point for wireless clients (either stationary or roaming), all you need to do is enable the wireless function, define the radio channel, the domain identifier, and the encryption options. Check Enable and click APPLY. 4-25 CONFIGURING THE BARRICADE Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the Barricade Wireless Router and all of your wireless clients. Be sure you configure all of your clients to the same values. Parameter ESSID Description Extended Service Set ID. The ESSID must be the same on the Barricade and all of its wireless clients. Transmission Rate The default is Fully Automatic. The transmission rate is automatically adjusted based on the receiving data error rate. Usually the connection quality will vary depending on the distance between the wireless router and wireless adapter. You can also select a lower transmission data rate to maximize the radio communication range. 4-26 WIRELESS Parameter Basic Rate Channel Description The highest rate specified will be the rate that the Barricade will use when transmitting broadcast/multicast and management frames. Available options are: All (1, 2, 5.5, and 11Mbps), and 1, 2Mbps (default is 1, 2Mbps). The radio channel must be the same on the Barricade and all of your wireless clients. The Barricade will automatically assign itself a radio channel, or you may select one manually. 4-27 CONFIGURING THE BARRICADE Encryption If you are transmitting sensitive data across wireless channels, you should enable encryption. You must use the same set of encryption keys for the Barricade and all of the wireless clients. Choose between standard 64-bit WEP (Wired Equivalent Privacy) or the more robust 128-bit encryption. You may automatically generate encryption keys or manually enter the keys. For automatic 64-bit security, enter a passphrase and click Generate, four keys will be generated. Choose a key from the drop-down list or accept the default key. Automatic 128-bit security generates a single key. Note:

The passphrase can consist of up to 32 alphanumeric characters. To manually configure the keys, enter five hexadecimal pairs of digits for each 64-bit key, or enter 13 pairs for the single 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.) Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. 4-28 WIRELESS MAC Address Filtering Client computers can be filtered using the unique MAC address of their IEEE 802.11 network card. To secure an access point using MAC address filtering, you must enter a list of allowed/denied client MAC addresses into the filtering table. (See Finding the MAC address of a Network Card on page 4-57.) Parameter Filtering Disable Enable Setting Permissions Prohibition Description Disables MAC address filtering. Enables MAC address filtering. Allows only devices with their MAC address in the list to connect to the Barricade. Denies access to the Barricade from devices with their MAC address in the list. 4-29 CONFIGURING THE BARRICADE NAT Some applications require multiple connections, such as Internet gaming, videoconferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these pages to specify the additional public ports to be opened for each application. Address Mapping Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. Enter the Public IP address you wish to share into the Global IP field. Enter a range of internal IPs that will share the global IP into the from field. 4-30 NAT Virtual Server If you configure the Barricade as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address). If you configure the Barricade as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address). 4-31 CONFIGURING THE BARRICADE For example, if you set Type/Public Port to TCP/80 (HTTP or Web) and the Private IP/Port to 192.168.2.2/80, then all HTTP requests from outside users will be transferred to 192.168.2.2 on port 80. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them. The more common TCP service ports include:

HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110. A list of ports is maintained at the following link:

http://www.iana.org/assignments/port-numbers. Note: The WAN interface should have a fixed IP address to best utilize this function. If your ISP only provides dynamic IP addresses, a search for free dynamic IP on any major search engine will turn up tools that will allow you to use the same domain name even though your IP address changes each time you log into the ISP. 4-32 ROUTING SYSTEM Routing System These pages define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters. Static Route Click Add to add a new static route to the list, or check the box of an already entered route and click Modify. Click Delete to remove an entry from the list. Parameter Index Network Address Subnet Mask Gateway Description Check the box of the route you wish to delete or modify. Enter the IP address of the remote computer for which to set a static route. Enter the subnet mask of the remote network for which to set a static route. Enter the WAN IP address of the gateway to the remote network. 4-33 CONFIGURING THE BARRICADE RIP Routing Information Protocol (RIP) sends routing-update messages at regular intervals and when the network topology changes. When a router receives a routing update that includes changes to an entry, it updates its routing table to reflect the new route. RIP routers maintain only the best route to a destination. After updating its routing table, the router immediately begins transmitting routing updates to inform other network routers of the change. Parameter Interface Operation Mode Version 4-34 Description The WAN interface to be configured. Disable: RIP disabled on this interface. Enable: RIP enabled on this interface. Silent: Listens for route broadcasts and updates its route table. It does not participate in sending route broadcasts. Sets the RIP (Routing Information Protocol) version to use on this interface. ROUTING SYSTEM Description A way in which a router tells its neighbor routers that one of the routers is no longer connected. None: No authentication. Password: A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets. MD5: MD5 is an algorithm that is used to verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to a specific individual. Password or MD5 Authentication key. Parameter Poison Reverse Authentication Required Authentication Code 4-35 CONFIGURING THE BARRICADE Routing Table Parameter Flags Description Indicates the route status:

C = Direct connection on the same subnet. S = Static route. R = RIP (Routing Information Protocol) assigned route. I = ICMP (Internet Control Message Protocol) Redirect route. Network Address Destination IP address. Netmask The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a 1 is part of the network/subnet number;

each bit that corresponds to 0 is part of the host number. The IP address of the router at the next hop to which matching frames are forwarded. The local interface through which the next hop of this route is reached. When a router receives a routing update that contains a new or changed destination network entry, the router adds 1 to the metric value indicated in the update and enters the network in the routing table. Gateway Interface Metric Note: Most modern routers support RIP-2 so there is usually no need for a static route table. 4-36 FIREWALL Firewall The Barricade Routers firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and number of active sessions, and provides the ability to detect and prevent certain types of network attacks. Network attacks that deny access to a network device are called Denial-of-

Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources. The Barricade protects against the following DoS attacks: IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. (See Intrusion Detection on page 4-42 for details.) The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select Enable and click the APPLY button to open the Firewall submenus. 4-37 CONFIGURING THE BARRICADE Access Control Access Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. The default is to permit all outgoing traffic. The Barricade can also limit the access of hosts within the local area network (LAN). The MAC Filtering Table allows the Barricade to enter up to 32 MAC addresses that are not allowed access to the WAN port. The following items are on the Access Control screen:

Parameter Normal Filtering Table MAC Filtering Table Description Displays the IP address (or an IP address range) filtering table. Displays the MAC (Media Access Control) address filtering table. 4-38 FIREWALL 1. Click Add PC on the Access Control screen. 2. Define the appropriate settings for client PC services (as shown on the following screen). 3. Click OK and then click APPLY to save your settings. 4-39 CONFIGURING THE BARRICADE URL Blocking The Barricade allows the user to block access to Web sites from a particular PC by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic Web sites. 4-40 FIREWALL Schedule Rule You may filter Internet access for local clients based on rules. Each access control rule may be activated at a scheduled time. Define the schedule on the Schedule Rule page, and apply the rule on the Access Control page. Follow steps to add schedule rule:

1. Click Add Schedule Rule. 2. Define the appropriate settings for a schedule rule (as shown on the following screen). 3. Click OK and then click APPLY to save your settings. 4-41 CONFIGURING THE BARRICADE Intrusion Detection 4-42 FIREWALL Intrusion Detection Feature SPI and Anti-DoS firewall protection (Default: Enabled) The Intrusion Detection Feature of the Barricade Router limits access for incoming traffic at the WAN port. When the SPI feature is turned on, all incoming packets will be blocked except for those types marked with a check in the Stateful Packet Inspection section. RIP Defect (Default: Enabled) If an RIP request packet is not replied to by the router, it will stay in the input queue and not be released. Accumulated packets could cause the input queue to fill, causing severe problems for all protocols. Enabling this feature prevents the packets accumulating. Discard Ping from WAN (Default: Disabled) Prevent a PING on the Gateways WAN port from being routed to the network. Stateful Packet Inspection This is called a stateful packet inspection because it examines the contents of the packet to determine the state of the communications; i.e., it ensures that the stated destination computer has previously requested the current communication. This is a way of ensuring that all communications are initiated by the recipient computer and are taking place only with sources that are known and trusted from previous interactions. In addition to being more rigorous in their inspection of packets, stateful inspection firewalls also close off ports until connection to the specific port is requested. When particular types of traffic are checked, only the particular type of traffic initiated from the internal LAN will be allowed. For example, if the user only checks FTP Service in the Stateful Packet Inspection section, all incoming traffic will be blocked except for FTP connections initiated from the local LAN. 4-43 CONFIGURING THE BARRICADE Stateful Packet Inspection allows you to select different application types that are using dynamic port numbers. If you wish to use the Stateful Packet Inspection (SPI) to block packets, click on the Yes radio button in the Enable SPI and Anti-DoS firewall protection field and then check the inspection type that you need, such as Packet Fragmentation, TCP Connection, UDP Session, FTP Service, H.323 Service, and TFTP Service. When hackers attempt to enter your network, we can alert you by e-mail Enter your E-mail address. Specify your SMTP and POP3 servers, user name, and password. Connection Policy Enter the appropriate values for TCP/UDP sessions as described in the following table. Parameter Fragmentation half-open wait Defaults Description 10 sec Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the router drops the unassembled packet, freeing that structure for use by another packet. Defines how long the software will wait for a TCP session to synchronize before dropping the session. Specifies how long a TCP session will be maintained after the firewall detects a FIN packet. The length of time for which a TCP session will be managed if there is no activity. The length of time for which a UDP session will be managed if there is no activity. The length of time for which an H.323 session will be managed if there is no activity. TCP SYN wait 30 sec TCP FIN wait 5 sec TCP connection idle timeout UDP session idle timeout H.323 data channel idle timeout 3600 seconds

Length of time before a half-open fragmentation session is detected as half-open. Length of time from detecting a flood attack to blocking the attack. Note: The firewall does not significantly affect system performance, so we advise enabling the prevention features to protect your network. 4-45 CONFIGURING THE BARRICADE DMZ If you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ (Demilitarized Zone) host on this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort. 4-46 SNMP SNMP Use the SNMP configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). Community A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the agent are controlled by community strings. To communicate with the Barricade, the NMS must first submit a valid community string for authentication. Parameter Community Access Valid Description A community name authorized for management access. Management access is restricted to Read Only (Read) or Read/Write (Write). Enables/disables the entry. Note: Up to 5 community names may be entered. 4-47 CONFIGURING THE BARRICADE Trap Specify the IP address to notify an NMS that a significant event has occurred at an agent. When a trap condition occurs, the SNMP agent sends an SNMP trap message to any NMSs specified as the trap receivers. Parameter IP Address Community Version Description Traps are sent to this address when errors or specific events occur on the network. A community string (password) specified for trap management. Enter a word, something other than public or private, to prevent unauthorized individuals from reading information on your system. Sets the trap status to disabled, or enabled with V1 or V2c. The v2c protocol was proposed in late 1995 and includes enhancements to v1 that are universally accepted. These include a get-bulk command to reduce network management traffic when retrieving a sequence of MIB variables, and a more elaborate set of error codes for improved reporting to a Network Management Station. 4-48 ADSL ADSL ADSL (Asymmetric Digital Subscriber Line) is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream.

Maximum data rate upstream. Maximum data rate downstream. Minimum noise margin upstream. Minimum noise margin downstream. Maximum fluctuation in the output power. Maximum reduction in the strength of the upstream signal. Maximum reduction in the strength of the downstream signal. There are two latency paths that may be used: fast and interleaved. For either path a forward error correction (FEC) scheme is employed to ensure higher data integrity. For maximum noise immunity, an interleaver may be used to supplement FEC. An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission. Indicates the number of Fast Path Cyclic Redundancy Check errors. Indicates the number of Interleaved Path Cyclic Redundancy Check errors. Momentary signal discontinuities.

The Barricade can be easily monitored through panel indicators to identify problems. Troubleshooting Chart Symptom LED Indicators Power LED is Off Action Check connections between the Barricade, the external power supply, and the wall outlet. If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet. If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact Technical Support for assistance. A-1 TROUBLESHOOTING Troubleshooting Chart Symptom LED Indicators Link LED is Off Action Verify that the Barricade and attached device are powered on. Be sure the cable is plugged into both the Barricade and the corresponding device. Verify that the proper cable type is used and that its length does not exceed the specified limits. Be sure that the network interface on the attached device is configured for the proper communication speed and duplex mode. Check the adapter on the attached device and cable connections for possible defects. Replace any defective adapter or cable if necessary. Network Connection Problems Cannot Ping the Barricade from the attached LAN, or the Barricade cannot Ping any device on the attached LAN Verify that the IP addresses are properly configured. For most applications, you should use the Barricades DHCP function to dynamically assign IP addresses to hosts on the attached LAN. However, if you manually configure IP addresses on the LAN, verify that the same network address (network component of the IP address) and subnet mask are used for both the Barricade and any attached LAN devices. Be sure the device you want to ping (or from which you are pinging) has been configured for TCP/IP. A-2 TROUBLESHOOTING Troubleshooting Chart Action Symptom Management Problems Cannot connect using the Web browser Forgot or lost the password Be sure to have configured the Barricade with a valid IP address, subnet mask, and default gateway. Check that you have a valid network connection to the Barricade and that the port you are using has not been disabled. Check the network cabling between the management station and the Barricade. Press the Reset button on the rear panel (holding it down for at least five seconds) to restore the factory defaults. A-3 TROUBLESHOOTING Troubleshooting Chart Action Make sure the wireless PC has the same SSID settings as the Barricade. See Channel and SSID on page 4-26. You need to have the same security settings on the clients and the Barricade. See Encryption on page 4-28. Move your wireless PC closer to the Barricade to find a better signal. If the signal is still weak, change the angle of the antenna. There may be interference, possibly caused by a microwave oven or wireless phone. Change the location of the interference sources or Barricade. Change the wireless channel on the Barricade. See Channel and SSID on page 4-26. Check that the AP antenna, connectors, and cabling are firmly connected. The distance between the Barricade and wireless PC is too great. Make sure the wireless PC has the same SSID and security settings as the Barricade. See Barricade. See Channel and SSID on page 4-26 and Encryption on page 4-28. Symptom Wireless Problems A wireless PC cannot associate with the Barricade. The wireless network is often interrupted. The Barricade cannot be detected by a wireless client.

Access Point (AP) An interface between the wireless network and a wired network. Access points combined with a distribution system (e.g. Ethernet) support the creation of multiple radio cells (BSSs) that enable roaming throughout a facility. Asymmetric Digital Subscriber Line (ADSL) One of four DSL technologies. ADSL is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream. Downstream rates range from 1.5 to 9 Mbps, whereas upstream bandwidth ranges from 16 to 640 kbps. ADSL transmissions work at distances up to 18,000 feet (5,488 meters) over a single copper twisted pair. Asynchronous Transfer Mode (ATM) A cell-based connection-oriented data service offering high speed (up to 2.488 Gbps) data transfer. ATM integrates circuit and packet switching to handle both constant and burst information. Frequently called cell relay. Authentication The process a station uses to announce its identify to another station. IEEE 802.11 specifies two forms of authentication: open system and shared key. Glossary-1 GLOSSARY Bandwidth The difference between the highest and lowest frequencies available for network signals. Also synonymous with wire speed, the actual speed of the data transmission along the cable. Basic Service Set (BSS) A set of 802.11-compliant stations that operate as a fully-connected wireless network. Cyclic Redundancy Check (CRC) An error detection process that (at the transmitting station) divides the data being sent by a particular polynomial and appends the resulting remainder to the transmitted data. Then (at the receiving station) the process divides the received data by the same polynomial and compares the resulting remainder to the remainder appended to the data at the transmitting station. If the remainders are equal, there is very high probability that no errors are present in the data. If they do not match, then errors are present. Domain Naming System (DNS) System used in the Internet for translating names of network nodes into addresses. Dynamic Host Configuration Protocol (DHCP) Issues IP addresses automatically within a specified range to devices such as PCs when they are first powered on. The device retains the use of the IP address for a specific license period that the system administrator can define. DHCP is available as part of the many operating systems including Microsoft Windows NT Server and UNIX. Glossary-2 GLOSSARY Ethernet A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor IEEE 802.3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable. File Transfer Protocol (FTP) A TCP/IP protocol for file transfer. Firewall A device that interfaces the network to the outside world and shields the network from unauthorized users. The firewall does this by blocking certain types of traffic. For example, some firewalls permit only electronic mail traffic to enter the network from elsewhere. This helps protect the network against attacks made to other network resources, such as sensitive files, databases, and applications. Forward Error Correction (FEC) A method of error control where the receiving node automatically corrects as many channel errors as it can without referring to the sending node. G.lite IEEE A standard that defines the more economical splitterless ADSL connection that transmits data at up to 1.5 Mbps downstream and 512 Kbps upstream. This ADSL option can be installed without an on-site visit by the service provider. Institute of Electrical and Electronic Engineers. Glossary-3 GLOSSARY IEEE 802.11 Specifies medium access and physical layer specifications for 1 Mbps and 2 Mbps wireless connectivity within a local area. IEEE 802.3x Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links. International Control Message Protocol (ICMP) Network layer Internet protocol that reports errors and provides other information relevant to IP packet processing. Documented in RFC 792. Local Area Network (LAN) A group of interconnected computer and support devices. LED Light emitting diode used for monitoring a device or network condition. Logical Link Control Layer (LLC) The highest layer of the IEEE 802 Reference Model and provides similar functions of a traditional data link control protocol. Management Information Base (MIB) Database of network management information that is used and maintained by a network management protocol such as SNMP or ICMP. The value of a MIB object can be changed or retrieved using SNMP or ICMP commands. MIB objects are organized in a tree structure that includes public (standard) and private (proprietary) branches. Media Access Control (MAC) A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes. Glossary-4 GLOSSARY Node Any network-addressable device on the network, such as a router or network interface card. Point-to-Point Protocol (PPP) A protocol that provides router-to-router and host-to-network connections over both synchronous and asynchronous circuits. PPP is the successor to SLIP. RJ-45 Connector A connector for twisted-pair wiring. Routing Information Protocol (RIP) A common type of routing protocol. RIP bases its routing path on the distance (number of hops) to the destination. RIP maintains optimum routing paths by sending out routing update messages if the network topology changes. For example, if a router finds that a particular link is faulty, it will update its routing table, then send a copy of the modified table to each of its neighbors. Service Set Identifier (SSID) An identifier attached to packets sent over the wireless LAN that functions as a password for joining a particular radio network (BSS). All radios and access points within the same BSS must use the same SSID, or their packets will be ignored. Simple Network Monitoring Protocol (SNMP) Defines the transfer of information between Management Information Bases (MIBs). Most high-end network monitoring stations require the implementation of SNMP on each of the components the organization wishes to monitor. Glossary-5 GLOSSARY Transmission Control Protocol (TCP) A commonly used protocol for establishing and maintaining communications between applications on different computers. TCP provides full-duplex, acknowledged, and flow-controlled service to upper-layer protocols and applications. User Data Protocol (UDP) A connectionless protocol that works at the OSI transport layer. UDP transports datagrams but does not acknowledge their receipt. UTP Unshielded twisted-pair cable. Virtual channel Identifier (VCI) A 16-bit field in the header of an ATM cell. The VCI, together with VPI, is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination. Virtual LAN (VLAN) A collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, allowing users to share information and resources located on the same LAN. Virtual Path Identifier (VPI) A 8-bit field in the header of an ATM cell. Wired Equivalent Privacy (WEP) An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network. The Wired Equivalent Privacy generates secret shared encryption keys that both source and destination stations can use to alter frame bits to avoid disclosure to eavesdroppers.
