Installation Starting the Probe Starting the Probe NOTE If you are using the Bootp server method of configuration, do not attach the power cord to the probe until told to do so in Chapter 4 “Bootp Server Configuration”. If you used the local terminal method of configuration, attach the power cord to the probe. The probe does not have a power switch, but is powered on when power is attached.
Installation Verifying the Installation Verifying the Installation You can verify the probe’s installation by looking at the status LEDs on the front or back of the probe. LEDs on the back of the probe show the status of each port and the LEDs on the front of the probe indicate the status of the 10Base-T/ 100Base-TX telemetry interface. After the probe restarts (boots), it runs a poweron self-test (POST) and then starts normal operations.
Installation Verifying the Installation Out-of-Band Troubleshooting For the Ethernet or Token-Ring telemetry interface, if the Activity LED is off, verify that the probe is properly connected to the telemetry network and that there is traffic on the network. Also, verify that you have the correct Physical Connector selected from the Modify/View Interface Values menu. If the ~ Line On or Power LED is off, verify that power is properly connected to the probe and to the correct power source.
Installation Verifying the Installation OC-3 ATM Troubleshooting There should be a cable connected to both connectors. Both Activity LEDs (from network and from equipment) should turn on when there are cells present on the network and the Cell Sync LED should be off. If both the Cell Sync LED and the Activity LED are turned on, the ATMProbe is sensing traffic on the network but is not able to synchronize on the cell stream.

4 Bootp Server Configuration
Bootp Server Configuration Bootp Server Configuration This chapter describes how to use the Bootp server method to configure the Agilent J3919A or J3972A OC-3 ATMProbe so that it can communicate over the network. This chapter assumes that you have already installed the probe, but have not attached the power cord. If you plan to use the local terminal method of configuration, skip this chapter and refer to Chapter 2 “Local Terminal Configuration”.
Bootp Server Configuration Probe Configuration Using a Bootp Server Probe Configuration Using a Bootp Server You can use a Bootstrap Protocol (Bootp*) server to load the probe’s IP configuration. This method requires that a Bootp server maintains a file containing client configuration information, maps from MAC addresses to IP addresses, and responds to requests from clients. You can configure the probe from an HP-UX, Solaris, or MS-DOS system acting as a Bootp server.

If power is removed from the probe (either by unplugging the power cord or from a power outage), this memory is preserved by power provided by the probe's internal battery.
their locations. It isolates the LANs from each other, allowing both sides to pass traffic internally. If a transmission from one LAN is addressed to a node on the other LAN, the bridge transmits it onto the other LAN for the destination node. Broadcast address The station address FFFFFF-FFFFFF. Packets intended for all nodes on a LAN use this address as the destination address. Broadcast packet A packet sent to all nodes on a LAN. Cell A cell is a fixed-length packet of bytes.
CLIP (Classical IP) IP over ATM conforming to RFC 1577. CLP Cell Loss Priority Collision The result of two or more nodes on a LAN transmitting at the same time, producing a garbled transmission. Common Part Convergence Sublayer (CPCS) The Common Part Convergence Sublayer (CPCS) is a part of the ATM Adaptation layer and provides message identification and error detection depending on the AAL type being used.
Convergence Sublayer The AAL is divided into two sublayers: the convergence sublayer and the segmentation and reassembly sublayer (SAR). These two sublayers convert whatever user data is to be transmitted into 48-byte cell payloads while maintaining the integrity and a certain amount of identity of the data involved. The result of each sublayer process is a Protocol Data Unit (PDU).
Cycle/Stuff Counter (C1) The Cycle/Stuff Counter (C1) is a 1-byte field in a PLCP frame that controls bit stuffing and length indication. The C1 byte occurs in the P0 (12th) cell of a PLCP frame.
exactly the same. Network devices based on both standards can co-exist on the same medium, but they cannot exchange data directly without special, bilingual software that can decode packets of both types. EtherTwist The Agilent Company’s version of 10Base-T. Extended LAN A network consisting of two or more LANs that are connected by bridges, routers, or other similar devices. Resources on the LANs can be accessed by users on any of the LANs. See also LAN.
FIDF FIDF is a 26-byte Transmission Header (TH) used for communication between adjacent SNA subarea nodes, provided both support Explicit and Virtual Route protocols, that use message sequencing. Fill Cell An empty or null ATM cell. This type of cell is a placeholder inserted into the signal stream to occupy bandwidth not allocated to a service. Fill cells are in either the Idle format (ITU-T) or Unassigned format (ATM Forum).
Half-duplex A form of communication where information can only travel one direction at a time. See also Full-duplex. Header Information at the beginning of a cell, frame or packet normally used for alignment, routing, operations or similar purposes. Header Error Control (HEC) The Header Error Control (HEC) is an 8-bit field and the fifth byte in the header of an ATM cell. The HEC value is calculated from the first four bytes of the cell header.

OSI Open Systems Interconnect. The 7 level communications structure promoted by ISO. Packet A bit stream consisting of predefined fields that contain data, addresses, and control information. In the IEEE 802.3 environment, this structure is often referred to as the MAC frame.
Path Overhead The Path Overhead (POH) is a 1 byte field in a DS3 PLCP frame that provides specific functions. The Z bytes (Z1-Z6) are reserved for future functions. The B1 byte is used for Bit Interleaved Parity (BIP-8) which checks for errors and performance conditions. The G1 byte is used for the PLCP Path Status which controls error conditions. The C1 byte provides for bit stuffing.
Payload Type Indicator (PTI) The Payload Type Indicator (PTI) is a 3-bit field that defines the contents of an ATM cell. The first bit determines if the cell is user data (0) or network signaling information (1). The second bit determines if there is no congestion (0) or congestion (1). The third bit identifies the SDU type (if it is a user cell) or the OAM type (if it is a control cell).
byte of overhead information used for path management. The entire frame is padded with either 13 or 14 nibbles of trailer to bring the transmission up to the exact bit rate used. DS3 was intended to accommodate clock slips so PLCP frames have to be padded with variable amounts to accommodate the extra “stuff” bits DS3 needs inserted for this clock slip feature. The C1 overhead byte indicates the length of the padding.
Protocol A set of rules that governs data transfer among devices on a network. A protocol identifies the handshake type, frame size and format, timing, error recovery scheme, word size or other characteristics of each transfer, depending on the system. Protocol Data Unit (PDU) A segment of data generated by a specific layer of a protocol stack; usually contains information from the next higher layer encapsulated with header and trailer data generated by the later in question.
SAR-PDU Segmentation and Reassembly Protocol Data Unit Scrambling An algorithm applied to a digital signal to eliminate long runs of all zeros or and ones which would make it difficult to recover the clock. The signal is unscrambled at the receiver to restore the original. Scrambling also eliminates the possibility of payload bit patterns accidentally mimicking an alignment or synchronization pattern at the start of a frame. Scrambling is only applied to the payload of ATM cells.
Service Specific Convergence Sublayer (SSCS) The Service Specific Convergence Sublayer (SSCS) is a part of the ATM Adaptation layer and handles timing and message identification depending on the AAL type being used. Services Layer The layer immediately above the adaptation layer in the hierarchy of telecommunications protocols. It is occupied by a particular client information service which is to be mapped into the cell layer by the adaptation layer.

Topology The organization of network devices in a network. FDDI uses a ring topology, Ethernet uses a bus Topology, and Token-Ring uses a ring topology. Trailer The last few octets or nibbles of a frame that fall outside the column and row view of the frame structure. Transmission Convergence Sublayer (TC) This sublayer of the physical layer maps ATM cells to and from the physical transmission medium with three key processes: cell delineation, cell synchronization, and cell rate decoupling.
Virtual Path Identifier (VPI) The Virtual Path Identifier is an 8-bit field in the ATM header.The VPI and VCI are used together to determine the destination address of the ATM cell. Vp (nominal Velocity of Propagation) The speed that a pulse travels along a given cable. Vp is expressed as a percentage of the speed of light in a vacuum. WAN (Wide Area Network) A data network engineered for relatively lower speed data transfers over unlimited distances. Often the links in a WAN are provided by a third party.
