4. IP address Internet Protocol Address A unique number that is assigned to each device which is to be connected to a TCP IP network Before using your analyzer on a network your network administrator will need to assign an IP address Glossary 3 Glossary An IP address consists of a 32 bit value presented in decimal dot notation 4 octets bytes separated by a dot For example the binary address 10000000 00000111 00001111 00000001 has the decimal dot notation of 128 7 15 1 network administrator Similar to system administrator network logging The collection and recording of network performance measures and other parameters and statistics NFS Network File System A standard network protocol for file sharing among different operating systems ping A utility that allows you to determine the status of the connections between devices and a network The ping utility is usually induded with software packages that provide networking services Your analyzer has a ping utility included in its firmware Glossary 4 protocol A set of conventions that specify how information will be formatted and transmitted on a network and how machines on a network will communicate relative pathname The specification of a node file or directory in a hierarchical file system relative to the current context dependent directory RPC Remote Procedure Call A client server protocol used to obtain a service from a remot

9. Point to Point Connections It is possible to connect a single computer to a single analyzer and avoid using a LAN hub To dothis you must use a special cross over cable or adapter which acts like a LAN hub See EIA TIA 568B Wiring on page 9 2 for wiring details If you try to create a point to point connection using a standard straight through cable it will not work For most applications the use of a LAN hub is simpler and additional devices can be added easily Some commercially available cross over cables do not implement the cross over wiring required for your analyzer Please refer to EIA TIA 568B Wiring on page 9 2 and verify all connections before using cables not made by Agilent Technologies Point to point connections may not work when connecting to older laser printers Older printers typically require a boot server for network use For a point to point connection with a printer use an HP Laser et 4 or newer Point to point connections do not require the use of proxy servers since no server is present in a point to point network connection To usea point to point connection first disable the use of a proxy server in your LAN software Refer to your software documentation for instructions how to do this LAN Interface Supplement 1 7 CAUTION Connecting and Configuring the Analyzer Configuring the Analyzer Configuring the Analyzer Before you configure your analyzer you will need to contact your netwo

49. N Interface Supplement Connecting and Configuring the Analyzer Configuring the Analyzer The Gateway Address If your analyzer will be communicating with devices on different physical networks you may need to have your network administrator assign a gateway IP address for you The gateway IP address is the address of a routing device that connects your analyzer s LAN with other LANS Set the gateway address to 0 0 0 0 if a gateway is not required See To Configure the Analyzer on page 1 10 to set this See Subnets and Gateways on page 8 15 for more information on gateway addresses The Subnet Mask If your analyzer will be communicating with devices on different physical networks you may need to have your network administrator assign a subnet mask number for you The subnet mask tells your analyzer whether a remote device is on the same LAN as your analyzer If your analyzer is attempting to communicate with another device the subnet mask defines whether your analyzer needs to route communications through the gateway Set the subnet mask to 0 0 0 0 if a subnet mask is not required See Configuring the Analyzer on page 1 8to set this See Subnets and Gateways on page 8 15 for more information on subnet masks The Ethernet Address Your analyzer has a unique built in Ethernet address associated with the LAN hardware inside it The Ethernet address is a 48 bit number assigned at the factory You don t have to know the Ethernet a
