List of Tables x Avaya M770 M-ACCF/SF ATM Access Modules User’s Guide
Chapter 1 Overview ATM Access Modules There are two M-ACC OC-12 ATM Access modules for the Avaya M770 Multifunction switch: • M-ACCF: 500m, Multimode fiber, can also be OC-3 reduced range • M-ACCSF: 15 km, Single-mode fiber, can also be OC-3 The M-ACC ATM Access modules need the following S/W Versions: • M-ACCF/SF ATM Entity S/W Version 1.8 • M-ACCF/SF X-Switch Module S/W Ver. 4.0.7 • M-SPX/M-SPS Embedded S/W 3.2.1 and higher.
Chapter 1 Overview networks. LANE allows users to interoperate with ATM or traditional LAN based servers over ATM for higher performance and functionality. ATM Access Module Features The following list summarizes the ATM access module features. These features are described in more detail in this guide. • Conforms to ATM Forum Standards • OC-12c 622Mbps Interface — SONET (STS 3c/STS 12c) compliant (SDH STM-1/STM-4) — Multimode fiber, SC/SM connectors — Single-mode fiber. • LAN Emulation (LANE) version 1.
Chapter 1 Overview Network Layer Concepts — LAN Emulation The following Sections describe the LAN emulation and ATM adaptation concepts behind the network layer architecture of a typical ATM network. Chapter 2 describes how to plan your ATM network and provides some examples of where to use the ATM access module within an ATM network.
Chapter 1 Overview LAN Emulation Server (LES) The LES coordinates and controls an Emulated LAN. It provides the central “directory” service of an emulated LAN to which a LEC can turn to look up the ATM address of another LEC. The LES directory contains a table of LAN destinations (LAN destination refers to either a MAC address or a Route Descriptor) together with the ATM addresses of the LECs that represent them.
Chapter 1 Overview Emulated LAN Connections LECs and LESs communicate with each other by means of ATM virtual channel connections (VCCs). Control signals and data transmissions are handled by separate VCCs: Control VCCs and Data VCCs. Figure 1.1 Basic LAN Emulation Client Connections Control VCCs The control VCCs carry control traffic such as LE_ARP requests and responses.
Chapter 1 Overview Table 1.1 Control VCCs (Continued) Initialized by VCC Name From/To Information carried Controldistribute LES==>LEC LES LES distributes control traffic to LECs, including LE_ARP information Duration Membership of LEC in ELAN Data VCCs Data VCCs carry data frames between LECs and between a LEC and the BUS. Unicast data is normally sent from one LEC to another LEC by data-direct VCCs.
Chapter 1 Overview Figure 1.2 illustrates the VCCs active among LAN Emulation Components. Figure 1.2 VCCs in LAN Emulation Components Frame Ordering There are two paths for unicast frames between a sending LAN Emulation Client and a receiving client: one via the BUS and one via a data direct VCC between them. For a given LAN destination, a sending client is expected to use only one path at a time, but the choice of paths may change over time.
Chapter 1 Overview Figure 1.3 shows the various stages of the flush protocol: Figure 1.3 The Flush Protocol. 5. Flus h_Res Switch Data Path from Multicast Send to Data Direct using Flush Protocol 6. Flush_Res 1. Data 2. Data h_Req 4. Flus 7. Data Operation of the LAN Emulation The following functions are performed by the LAN Emulation. The LAN Emulation Clients (LEC) and the LAN Emulation Servers interact by way of a well-defined interface (LUNI).
Chapter 1 Overview The LECS Connect and Configuration phases may be bypassed for certain applications. The Registration phase may also be bypassed if the LEC performs required address registration during the Join phase. The Processes connecting the LEC to the ELAN are shown in Figure 1.4. Figure 1.4 Connection Processes of the LEC to LANE Server Registration The address registration function is the mechanism by which LECs provide address information to the LAN Emulation Server.
Chapter 1 Overview Address Resolution Address resolution is the procedure by which a LEC associates a LAN destination with the ATM address of another LEC or the BUS. Address resolution allows clients to set up data direct VCCs to carry frames (refer to Figure 1.5). Figure 1.5 Address Resolution Connection Management In Switched Virtual Connection (SVC) environments, the LAN Emulation entities (LEC, LES and BUS) set up connections between each other using UNI signaling.
Chapter 1 Figure 1.6 Overview LAN Emulation Components Server (LES) ATM Network BUS Client (LEC) Client (LEC) Router LECS (optional) Note: The router shown in Figure 1.6 is not a LAN Emulation component, but would be required should a device on one Emulated LAN need to communicate with a device on another Emulated LAN. LAN Emulation and Avaya Devices LAN Emulation components are implemented in ATM devices.
Chapter 1 Overview Joining the ELAN Before a LAN Emulation Client (LEC) can transmit any Ethernet frames onto the ATM network it must first join an ELAN. To join the ELAN: 1 The LEC must know the name of the ELAN it is to join. The ELAN name is specified through the management software on the Switch. 2 The LEC must communicate with the LAN Emulation Server (LES) that is serving that ELAN. To communicate with the LES, the LEC must first locate the LES.
Chapter 1 Figure 1.7 Overview LAN Emulation Clients and Ethernet Hosts Hosts with MAC Addresses Avaya M770 Multifunction Switch ATM Port with 16 LAN Emulation Clients (LECs) each with an ATM Address ATM Access Module These clients represent (act as a proxy for) devices connected to the Ethernet ports.
Chapter 1 Overview LAN Emulation Address Resolution Protocol (LE_ARP) An LE_ARP request is sent to the LES to locate the destination MAC address. The LES in turn sends the LE_ARP request to all of the LECs in the Emulated LAN. LECs represent (act as a proxy for) MAC address devices connected to the Ethernet ports. When a LEC receives an LE_ARP request it checks whether the MAC address is on its Switch. It does this by checking the entries in the Switch database.
Chapter 1 Overview Network Layer Concepts — ATM & ATM Adaptation This Section describes the following concepts behind the network layer architecture of a typical ATM network: • The Layered Network Architecture • ATM Adaptation Layer (AAL) • Asynchronous Transfer Mode (ATM) Layer • Physical Layer The Layered Network Architecture Asynchronous Transfer Mode (ATM) is one part of the layered network architecture. This architecture is shown in Figure 1.8.
Chapter 1 Overview ATM Adaptation Layer (AAL) Ethernet frames can be between 64 and 1514 bytes in length. ATM transmits data in fixed length cells. Each cell contains 48 bytes of user data. The ATM Adaptation Layer (AAL) converts data between the Ethernet and ATM formats. The AAL has a Segmentation and Reassembly (SAR) sub-layer that does the conversion. In the sending device the LEC passes the Ethernet frames to the SAR.
Chapter 1 Overview physical layer technology to share the same higher layer — the ATM layer. ATM uses fixed length packets called cells. The ATM cell is defined as 48 bytes of payload and 5 bytes of header information totaling 53 bytes. The header contains enough information to allow the network to forward each cell to its proper destination. The cell header also provides the network with the ability to implement congestion control and traffic management mechanisms.
Chapter 1 Overview Cells are de-multiplexed at the other end of the connection and forwarded to the correct service destination. Multi-service processing promotes scalability by significantly reducing the number of changes needed to add new service traffic types to your network. ATM is Connection-Oriented ATM is a connection-oriented transport service that requires a communication channel to be set up between the ATM source and destination end-systems before ATM cells can pass between them.
Chapter 1 Figure 1.11 Overview Connection Terminology Edge-device Virtual Channel ATM ATM Switch Switch ATM Switch A A B Virtual Channel Edge-device Virtual Channel Virtual Channel Connection (VCC) (Also known as Virtual Circuit or Call) Many virtual channels can exist on the same physical link. Each virtual channel is identified by a pair of numbers: • The Virtual Path Identifier (VPI) and • The Virtual Channel Identifier (VCI).
Chapter 1 Overview Connections that are established dynamically using the Signalling protocol are known as Switched Virtual Circuits (SVCs). Switched Virtual Circuits are described on Page 20. ATM connections can also be established via management, and these type of connections are known as Permanent Virtual Circuits (PVCs). Figure 1.12 Switching Cells Using VPI and VCI Values M770 Multifunction Switch with M-ACC Each cell is switched through the ATM network.
Chapter 1 Overview ATM Interfaces ATM technology is implemented in ATM edge-devices and ATM Switches. ATM provides a User-to-Network Interface (UNI). The User-to-Network Interface (UNI) is used to connect an ATM edge device to an ATM switch that is managed as part of the same network. ATM also provides a Network-to-Network Interface (NNI) that is typically used to interconnect two ATM switches managed as part of the same network. The ATM Interfaces are shown in Figure 1.13. Figure 1.
Chapter 1 Overview Figure 1.14 UNI Management Entities Avaya M770 Multifunction Switch (M-ACCF OC-12 Module) UME in ATM Access Module ATM Switch UME (M770 ATM Switch) ATM Address Registration In order to establish an ATM connection, both the user and the network must know the ATM addresses used at that User-to-Network Interface (UNI). An example of an ATM address is shown below. 47.00.79.00.00.00.00.00.00.00.00.00.00.00.A0.3E.00.00.01.
Chapter 1 Overview The ATM cell has 48 bytes of payload (information to be carried) and five bytes of header information, making the cell 53 bytes in length. The cell header contains the information used by the network to forward each cell to its destination. The ATM cell structure is shown in Figure 1.15. Figure 1.
Chapter 1 Overview Physical Layer The physical layer is responsible for transmitting and receiving ATM cells over a physical medium. It is also responsible for checking the integrity of the bits being transferred over a physical media, and for making sure that they are error-free. The ATM access module is compliant with both SONET STS-3c and SDH STM-1 physical layer standards. These standards are similar, and most devices allow you to use either framing standard on each link in the ATM network.
Chapter 1 Overview Note: ELAN-to-VLAN and VLAN-to-ELAN mapping is only one-to-one. Unassociated packets/cells are discarded. Figure 1.
Chapter 1 Overview Figure 1.17 Extending VLANs into the ATM Network.
Chapter 2 Applications Putting Your ATM Network Together This Section takes you through the process of planning your network. Topics include: • Planning Your Network • ATM Configuration Rules • Extending VLANs Through the ATM Network • ATM Connections Within Your Network. Planning Your Network Before installing your ATM devices you should spend some time planning your network structure. This section lists some of the points you should consider.
Chapter 2 Applications Note: For the ATM access module these requirements are specified in Appendix A, Specifications. For other devices, refer to the user guides that accompany those devices. • Does your network conform to the ATM configuration rules? Ensure that your network meets the configuration rules described below. ATM Configuration Rules There are several things that you should consider before configuring your network: • Your cables and equipment must meet all of the technical specifications.
Chapter 2 Applications Extending VLANs Through the ATM Network When setting up VLANs and extending them into the ATM network you should consider the following (see Figure 1.17): • What logical network domains, VLANs, do you wish to set up? Traffic from one Emulated LAN (ELAN) will not be seen on another ELAN (unless a router is used), as they are logically separate domains. For this reason you should consider: — What ELANs you require. — How the VLANs will map to the ELANs.
Chapter 2 Applications Note: Configuring the LECS and LES is outside of the scope of this user guide. Consult the user guide that accompanies the device implementing the LECS or LES. Alternatively, if your LEC will not be using a LECS and is being configured manually, ensure that: — The LES address that the LEC is using has been correctly entered via the local management screens. — The LES is active.
Chapter 2 Applications Network Configuration Examples This Section provides examples of possible network configurations using the M-ACC module. If you are unfamiliar with ATM, see the Section, entitled Planning Your Network. ATM Backbone in the Building An example of an ATM backbone within a single building, is shown in Figure 2.1. In this case, the Ethernet Switch on each floor is provided with a high speed (622 Mbps) full duplex link to the backbone.
Chapter 2 Applications Figure 2.
Chapter 2 Applications Avaya M770 Multitechnology Functionality This section gives an example of ATM within a WAN environment connecting various sites. Using the M-ACC module we can leverage the Multifunctionality of the Avaya M770 and connect Fast Ethernet PC desktops to the same single chassis. In Figure 2.2, ATM was chosen to efficiently transfer both voice and data on a single trunk.
Chapter 2 Applications Routing in the X-Switch Domain The principle behind the Avaya routing evolution is to move routing from the backbone to the edges. This controls the traffic from the moment it enters the LAN and not just after it reaches the backbone. Figure 2.3 shows how an M-MLS routing module in one of the 2 Avaya M770 Multifunction switches can provide routing for all users on either side of the ATM network. The Avaya M770 is connected to the ATM cloud via the M-ACC ATM Access Modules.
Chapter 3 Installation Installing the M-ACC Module Safety Information Warning: Before installing or removing any components of a device, or carrying out any maintenance work, you must read the safety information provided in Appendix A, Important Safety Information. Disconnect the device from the main power supply. Warning: Installation and removal of the ATM access module must be carried out by qualified personnel only.
Chapter 3 Installation Single-mode Module Laser Classification CLASS 1 LASER PRODUCT Note: Class 1 lasers are inherently safe under reasonably foreseeable conditions of operation. Caution: The use of optical instruments with this product will increase eye hazard. Multi-Mode Module LED Warning The following warnings apply to the M-ACCF ATM access module equipped with multi-mode fiber. Class 1 LED Product Warning: Class 1 LED Product.
Chapter 3 Installation Domain Usage Considerations The M-ACC is a DomainX module of the Avaya M770. The maximum number of DomainX modules you can insert in the hub is determined by domain usage considerations, as follows (M-SPX refers to either the M-SPV, M-SPX or M-SPS in the following examples): The Avaya M770 allows a maximum of 100 Domain Resource Units (DRUs) for DomainXL (Left DomainX - slots 1-7) and the M-SPX, and 100 DRUs for DomainXR (Right DomainX - slots 8-14) and the M-SPX.
Chapter 3 Installation Note: A redundant M-SPX does not count in the DRU calculations. However you must include the active M-SPX twice, once for DomainXL and once for DomainXR. DRU Budget Information Window You can check the DRU budget information for your Avaya M770 hub via the CajunView ‘ Network Management System (NMS). The following window shows an example of a chassis with an M-SPV, M32-100T, M12-100F and an M12-100T module.
Chapter 3 Installation Installing the Module Caution: The ATM access modules contain components sensitive to electrostatic discharge. Do not touch the circuit board unless instructed to do so. Note: The Avaya M770 chassis must not be operated with the module slot open; the slot should be covered with the supplied blanking plate if necessary. Note: M-ACC modules are hot swapable. The M-ACC occupies one slot in the Avaya M770 chassis and can be inserted into any available slot.

Wait until the Port LEDs blink before commencing work. Connecting a Cable to the ATM Port 1 Ensure that the cable you wish to connect to the port meets the correct specification.
Chapter 3 Installation Power On Self Test When you power up the Avaya M770 switch with an M-ACC module inserted, both pass a self test. This check takes between 10 and 20 seconds to complete, and includes: — Checksum tests of boot and system areas of Flash memory — System memory tests — MAC address verification test — System timer test — CAM (Contents Addressable Memory) tests — Console Port tests — Internal packet forwarding tests — ASIC tests — Module interface tests — Module packet forwarding tests.
Chapter 3 Installation Post-Installation Checks Figure 3.2 shows M-ACC front panel with its LEDs, switches and connectors (described in Table 3.2). When you insert an M-ACC ATM Access module into the Avaya M770 chassis or after a reset, there is a Startup sequence which takes about 30 seconds before the ATM lights ON. Table 3.
Chapter 3 Installation Configuring the M-ACC Module The M-ACC module can be configured using the text-based Command Line Interface (CLI) utility and the Terminal Interface. The LEC Information Table, ATM Access module and ATM port information can be viewed using CajunView™. For instructions on the text-based utility, see Chapter 4. For information about the graphical user interfaces, see Chapter 5. For instructions on the use of the graphical user interfaces, refer to the Manager User’s Guide on the CD.
Chapter 3 Installation The RJ-45 port on the front of the module is labeled “Console”, and may be used to configure the switch using the built-in Command Line Interface (CLI, Terminal Emulation). In the future, this connector will also be used for out-of-band SNMP management, via a modem. The port settings are as follows: • Baud Rate - 9600 bps • Character Size - 8 • Parity - None • Stop Bit - 1 • Flow Control - None • We recommend using a VT-100 terminal to enable access to all CLI features.
Chapter 3 Installation Setting up the M-ACC Module Before you can set up the M-ACC module you must power on and set up the Avaya M770 switch as described in the Avaya M770 User Guide. The following steps describe how to configure the M-ACC module using the Avaya M770 CLI. Changing the Default IP Address of the M-ACC Module Using the CLI To begin using the ATM access module you must first assign an IP address and ATM capabilities to the module via the CLI of the X-switch CPU.
