Frame Data organized in bytes encapsulated with a header and a trailer containing information regarding the data. Frame and packet are sometime used interchangeably.

Frame Type The format of the frame. Some examples are:

SNAP/IP, SNAP/IPX, 802.3/802.2, EthernetII/IP,

EthernetII/IPX, 802.3/IPX, 802.2/IPX.

FTP File Transfer Protocol - Internet protocol for transferring files from one computer to another.

Hop A data link through a bridge or router between stations on a network. For example: Agilent.com is 6 hops away from my PC.

ICMP Internet Control Message Protocol - The IP layer protocol for handling errors and control messages.

IP Internet Protocol. The protocol developed and used in the Internet. It is now used in nearly all public and private networks. It provides an addressing structure that allows relaying of packets in a manner that is logically separated from the underlying physical network. It is a connectionless, best effort protocol designed to work across dissimilar networks.

IP address A four-byte address always written in decimal with each byte separated by dots. This is an address normally assigned through software and associated with a hardware address of a network interface card. It can also be associated with a resource on the network such as an SNMP agent.

IPX Internetwork Packet Exchange - Novell Netware’s network layer protocol, it handles network addressing, routing and packets.

Locate Using SNMP, report the switch or hub port that a station is connected to.

MAC address The unique address of each hardware component, NIC card, hub, switch, etc., on a network. These are assigned by the manufacturer of the networking equipment when the hardware is produced.

MAC Loopback The process of transmitting and receiving packets at the MAC layer and reporting delay, the quantity transmitted and received as well as any errors which occur.
