Figure 2-1 NMSetup Step 1 For a detailed description of the NMSetup Tool see page 1-43. Configuring SNMP SmartAgents on Devices The NMS performs physical layer management using the SNMP. The NMS polls agents for status, configuration and network traffic information.
Configuring SNMP SmartAgents on Devices 2-3 (NMS). This allows the NMS to access these devices directly over the ATM network instead of going across routers. 3 Configure the IP address, and default gateway of Bridge 0 in each of the edge device units. See the device Installation and Setup Guide for the devices you are using. Configuring SNMP SmartAgents and Parameters Community names set on the NMS must correspond with community names set on the agent(s).
2-4 CHAPTER 2: CONFIGURING AND LAUNCHING THE ATM AND VLAN MANAGER CAUTION: Do not start the ATM and VLAN Network Manager until all the ATM and VLAN devices have been discovered and appear in the IP Map of the management platform. Setting Up for Distributed Polling Polling in SNMP management is the activity whereby the NMS interrogates/polls individual nodes on the network for their current status. It is one if the most important sources of network management control for traffic on the network.
Configuring SNMP SmartAgents on Devices 2-5 The following steps must be followed when installing distributed pollers: 1 Install the Transcend ATM and VLAN Management application on the central machine on top of an open management platform such a HPOV. In a distributed polling environment, this machine is the Central Viewing Station or Central Management Console or install the Transcend ATM and VLAN Management application as a stand-alone application, on other Unix machines (Solaris, AIX or HPUX).
2-6 CHAPTER 2: CONFIGURING AND LAUNCHING THE ATM AND VLAN MANAGER An Example of Distributed Polling. 100.200.100.170-180:100.200.100.78:1161 100.200.100.*:100.200.100.79:1161 100.*.*.*:100.200.100.77:1161 *.*.*.*:127.0.0.1:1161 Figure 2-2 A Listing of Contents from the C:\TranscendNT\ATMvLAN\runtime\cnf\mediationd.cnf Line one displays the range of IP addresses (IP address 100.200.100) with their last address field, address ending in numbers between 170 through 180, polled to IP address 100.200.100.
Device Configuration for VLANs in ATM Networks Device Configuration for VLANs in ATM Networks 2-7 A Virtual LAN is logical port group spanning a single device or multiple devices on a network forming a single broadcast or flooding domain. When LAN Emulation protocols are used to create broadcast domains over ATM-based infrastructures, these broadcast domains are also commonly known as Emulated LANs or ELANs.
2-8 CHAPTER 2: CONFIGURING AND LAUNCHING THE ATM AND VLAN MANAGER 3 The Network Management Station should be connected directly to the switch running the primary LECS. This will ensure that the NMS always has access to the LECS so that it can enable the backup LES when the primary LES fails. See “Description of LES/BUS Redundancy” on page 4-10. The CB7000 Fast Setup Tool This CB700 Fast Setup icon opens a wizard that allows to configure the CoreBuilder 7000. To use the Fast Setup Tool.
Device Configuration for VLANS in Non-ATM Networks Device Configuration for VLANS in Non-ATM Networks 2-9 Virtual LANs in non-ATM (Fast Ethernet) environments are created by using Layer 2 encapsulation or Tagging as a means to create broadcast or flooding domains. Ports that are common to multiple Virtual LANs are known as Virtual LAN Trunks (VLT). Switch 1000/3000s and CoreBuilder 5000 Fast Modules support this feature.
2-10 CHAPTER 2: CONFIGURING AND LAUNCHING THE ATM AND VLAN MANAGER Starting Up the ATM and VLAN Manager This section describes the start-up procedure for the ATM and VLAN Management application for the HPOV/OVW platform: Setting Up and Customizing the ATM and VLAN Management Application Before you begin to use the ATM and VLAN Management application there are several tasks that you should perform to setup and customize the ATM and VLAN Management application.
Starting Up the ATM and VLAN Manager 2-11 discovery database, you can manually discover devices using the Manual Device Discovery Assistant. See “Using the Manual Device Discovery Assistant” on page 4-2. Verify that your network is up and running. As the application begins, it is modeling (understanding the logical and physical structure) the ATMvLAN network. The length of this process depends on the size of the network. For larger networks, it may take up to 15 minutes for your maps to be activated.

OPERATING THE ATM VLAN MANAGER II AND This section provides step-by-step instructions for performing network management tasks using the ATM and VLAN Management application.
-22 CHAPTER :
4 NETWORK CONFIGURATION TASKS This chapter describes how to perform the following ATM and VLAN Management network configuration tasks using various configuration assistants.
4-2 CHAPTER 4: NETWORK CONFIGURATION TASKS ■ clear the entire database You can sort all the device types according to all the fields contained in the ATM and VLAN Devices database. After you modify, change, add or delete devices from the ATM and VLAN database you must restart the application for the modifications to take effect. Using the Manual Device Discovery Assistant To discover devices manually, you need to set the discovery mode to Manual Discovery mode.
Configuring Manual Device Discovery 4-3 The Manual Discovery window is displayed in Figure 4-1. Figure 4-1 Manual Discovery Setup Window All devices appear initially with the default Community Name and Polling Interval settings. These entries may be modified by changing the Community Name in the appropriate field or using the Polling Interval cascade to select a new value. The window is divided into three sub-windows. The first section displays all parameters pertaining to the selected device type.
4-4 CHAPTER 4: NETWORK CONFIGURATION TASKS Adding Devices 1 Enter the device’s parameters in the display fields of section 1 2 Click Add. Modifying Devices 1 Double click on a row In the scrolling region. The device and its parameters appear in the display fields of section 1 or select a Device Type from the cascade in section 1 and enter its parameters. 2 Click Add. The System verifies that the IP address is unique before adding a device to the database. Repeat for adding multiple devices.
Configuring LAN Emulation Services 4-5 To use the Locator Tool to view the Manual Discovery database: 1 Select the Locator Tool. 2 Select the Device Database tab. See Figure 4-2. 3 Select Search to display all the parameters in the database. The parameters are displayed. To conduct a search based on a specified parameter. 1 Select the parameter from the Search Field. 2 Enter the search string (may be a partial value) in the Value field. 3 Select Search.
4-6 CHAPTER 4: NETWORK CONFIGURATION TASKS ■ Set up the LECS database (Set the primary LES and set the backup LES of each ELAN) ■ Activate the Automatic LANE Redundancy Monitor ■ Setup for Quick LANE Redundancy Figure 4-3 The Backbone and Services Configuration Window
Configuring LAN Emulation Services 4-7 To access the Backbone and Services Configuration Assistant: 1 From the LAN Emulation map or Topology Browser LAN Emulation component, select the Backbone and Services icon or branch. 2 Select the Configuration icon from the Topology Browser or from the ATMvLAN menu. The Backbone and Services Configuration Assistant window is displayed as shown in Figure 4-3. The top sub-window within this setup screen allows for the setup of the LECSs in the network.
4-8 CHAPTER 4: NETWORK CONFIGURATION TASKS LECS Database Creation and Synchronization The second section is used to build the LECS database. This section allows you to enter LAN Emulation Servers (LES) and their corresponding backup LAN Emulation Servers into the LECS database. Initially, the LECS database window shows the default LECS database displaying only a subset of the LAN Emulation Servers that exist in the network.
Configuring LAN Emulation Services 4-9 primary LES is actually down and activate the backup LES upon completion of the vital checks. These vital checks only take a few seconds (10-15 seconds) to complete. Quick LANE redundancy mode is recommended for most networks.
4-10 CHAPTER 4: NETWORK CONFIGURATION TASKS 4 The Network Management Station should have direct access to at least one LECS in the network, when an ELAN fails. 5 Do not use too many primary LESs on a single switch. Distribute the LESs across the backbone. 6 Sixteen is the default number of active LANE Servers (LES) per CoreBuilder7000 that can be viewed in LAN Emulation maps.
Configuring LAN Emulation Services 4-11 When LAN Emulation redundancy is activated on the NMS, see Activating LANE Redundancy, and when a switch running the primary LES fails, the NMS detects the failure. For the description of failure resolution, see “LES Failure Resolution” on page 4-11. The backup LES in the LECS database is then activated. It is critical that the NMS be connected directly to the switch running the LECS or have direct access to this switch.
4-12 CHAPTER 4: NETWORK CONFIGURATION TASKS down. If a LEC cannot bind to the backup LES, it is necessary to check if the LEC can connect to the LES and the LES can in turn, connect back to the LEC. Correct E-IISP planning for route failover/redundancy is required for LANE redundancy to work. How Does The Primary LES Regain Control of the ELAN? The primary LES will not automatically start serving the ELAN when it becomes active again, if the backup LES is activated.
Configuring LAN Emulation Services 4-13 Since an LECS may be located on the same switch as the primary LES, if the primary LECS (primary LECS is the one on the top of the priority list) fails along with the primary LES, its database cannot be altered by the “LANE Monitor” to point to the backup LES when the LES failure condition happens. This LECS’s database still points to the primary LES while all the other LECSs point to the backup LES.
4-14 CHAPTER 4: NETWORK CONFIGURATION TASKS Each ELAN contains two entries of LES addresses. 5 For each ELAN, select the LES that was not automatically changed. 6 Click Apply to update the database. Manual LANE Redundancy operates on only one LECS at a time. You can select the LECS in the Topology Browser or in the Backbone and Services map. The Automatic LANE redundancy monitor, see the description on page 4-8, must be disabled and then restarted after manually fixing the LECS database.
Configuring LAN Emulation Services 4-15 a Move the ports in the backup ELAN to a temporary ELAN using the VLAN move option. Then move the ports from the temporary ELAN to the primary ELAN. It is important to first move to temporary ELAN first and this temporary ELANID must be in the LECS database. b Software reset the backup LES/BUS after modifying the database. The software reset of the LES/BUS must be done via the Command Line Interface of the CB7000.
4-16 CHAPTER 4: NETWORK CONFIGURATION TASKS An Example of Setting Up and Activating LANE Redundancy The following is an example of a simple 2 CoreBuilder 7000 setup demonstrating the LES/BUS and LECS redundancy. Equipment (Hardware) [CoreBuilder 7000 B]-----[CoreBuilder 7000 A]------[7200/2700 A] [2700/7200 B]---------[NMS] Software 3.
Configuring LAN Emulation Services 4-17 To configure the NMS: 1 Connect the NMS to port 1 on one of the 2700s. 2 Ping all the devices. Be certain that both the CoreBuilder 7000 management ports are connected to the bridge 0 ports on the 2700s. Make sure they appear in the HPOV IP map. 3 Run the ATMvLAN application. Make sure all that all the devices appear in the ATM Devices Map and that the LES/BUSs from both the CoreBuilders appear in the LAN Emulation Backbone and Services map.
4-18 CHAPTER 4: NETWORK CONFIGURATION TASKS To setup LANE Redundancy (LES/BUS/LECS): 1 From the LANE Emulation map or Topology Browser, select the Backbone and services icon or branch. 2 Select the Configure icon or Configuration Assistant from the ATMvLAN menu. The Backbone and Services window is displayed as in Figure 4-5.
Configuring LAN Emulation Services 4-19 To setup LECS priority: 1 Make sure the LECS with on the B* switch is the first one in the list. If not, change the order using the middle mouse button. 2 Click Apply. This applies the two active LECS addresses to each switch. The LECS on switch B* is the primary one. To setup the LECS database for LES/BUS redundancy: 1 In the second section of the dialog box, set the ELAN ID for Admin/Default VLAN using the appropriate toggles.
4-20 CHAPTER 4: NETWORK CONFIGURATION TASKS At this stage, the “LANE Monitor” tracks LES/BUS failure and activates redundancy if there is a failure of primary LES. Bridge 0’s LES/BUS is on CoreBuilder 7000 A and its backup is on CoreBuilder 7000 B. Bridge 1's LES/BUS is on CoreBuilder 7000 B and its backup on CoreBuilder 7000 A. Both switches have LECS databases and each LECS database has the admin ELAN pointing to switch A LES/BUS ELAN_ID. Following this procedure, check all the above steps once again.
Configuring VLAN Aliases and Colors 4-21 All the LECs join the new “admin” ELAN since the LECS points them to the new “admin” LES. It takes approximately 15 seconds to update the LECSs via Transcend Management Software. It takes about two minutes to reboot the switch with the old LES, and about five to fifteen minutes for all the LECs to join the new LES.
4-22 CHAPTER 4: NETWORK CONFIGURATION TASKS The following steps listed below illustrate the VLAN alias and color setup. This procedure is common for both ATM-based VLANs as well as non-ATM VLAN alias setup. 1 From the Root window select the Virtual LANs icon and then from the ATMvLAN menu select Configuration Assistant or in the Topology Browser select a Virtual LANs component and then select the Configure icon.
Configuring VLAN Aliases and Colors 4-23 5 Click Apply to update the database. If you do not click Apply, none of your changes are entered into the database. Before you begin changing/moving VLANs in the network, you must define the admin and default VLANs using this option. Select the ELAN that the admin VLAN is using. Enter the “admin” in the entry field and click Add and then click Apply. Retaining VLAN Aliases and Colors You can retain VLAN aliases and colors for subsequent installations.
4-24 CHAPTER 4: NETWORK CONFIGURATION TASKS To conduct a search based on a specified parameter. 1 Select the parameter from the Search Field. 2 Enter the search string (may be a partial value) in the Value field. 3 Select Search. Figure 4-7 Locator Tool VLAN Aliases and Colors Configuring Policy-based VLAN Auto-configuration This section describes the implementation of Policy based VLAN autoconfiguration in ATM based VLAN environments.
Configuring Policy-based VLAN Auto-configuration 4-25 auto-configuration can be extended to include protocol-based VLAN auto-configuration and application-based VLAN auto-configuration. Automatic Configuration of VLANs and Network Security One of the most important considerations in automatic VLAN configuration is network security. Network administrators must have complete control over how known users access and use the network.
4-26 CHAPTER 4: NETWORK CONFIGURATION TASKS Integrated TEM/Unix or TEM/NT Based VLAN Server. This server is integrated with the TEM application and is use in policybased VLANs. Policy-based VLANs are supported on ATM-based switches such as the CoreBuilder 7000/7x00, SuperStack II Switch 1000 with ATM downlink, Switch 3000 with ATM downlink and Desktop Switch with ATM downlink.
Configuring Policy-based VLAN Auto-configuration 4-27 ATMvLAN application to recognize and communicate with an NT based stand-alone VLAN Server (IP address and SNMP community string). Configuring MACbased VLAN Auto-configuration Policy This section describes how to configure devices to enforce the MAC-based policy. When a device is configured for the MAC-based policy, it automatically partitions its ports into VLANs, based on the MAC address of the endstation that is attached to its ports.
4-28 CHAPTER 4: NETWORK CONFIGURATION TASKS 4 Using the Build UDB tool, do an inventory of the network so that the MAC address location (device/port/VLAN) where this PC is attached to is learned and stored. Build UDB Tool The Build UDB tool can be configured to do an MAC address inventory of the entire network or a selected subset of devices on the network. To open the Build UDB Tool, see Figure 4-8, start the tool from the by selecting the Users icon.
Configuring and Using the MACvDB Configuring and Using the MACvDB 4-29 The MACvDB is used to perform the following two functions: 1 Finding a MAC address in the network. 2 Mapping MAC addresses to VLANs. Finding a MAC Address Locating a MAC address allows the network administrator to see which switch the endstation is attached to. Mapping a MAC Address to a VLAN This feature is used by the MAC-based policy to determine the MAC address to VLAN mapping.
4-30 CHAPTER 4: NETWORK CONFIGURATION TASKS The Search History indicates the searches you have perform thus far. To display the contents of your database: ■ Select Search. Once the parameters appear in the display section you can edit or modify the database. It is recommended that you use the Edit mode if you are going to perform extensive modification to the database.

Configuring and Using the MACvDB 4-31 A warning message appears. Figure 4-9 The Locator Tool/MACvDB Tab Apply the MAC-based VLAN Auto-configuration to the Devices To apply the MAC-based auto-configuration policy to the devices you have to move the devices into the MAC-based policy.
4-32 CHAPTER 4: NETWORK CONFIGURATION TASKS This removes the device from the policy. Once a device or port is put into a policy, all open/unused ports are automatically placed into the default VLAN. You will notice a message on the NMS screen saying that VLAN move has taken place. Verify that Automatic VLAN Auto-configuration is Activated.
Configuring IP Subnet-based VLAN Auto-configuration 4-33 To configure of IP Subnet -based policy on devices you have to populate the VLAN server database with IP-Subnet to VLAN mapping information. 1 Start the Locator Tool and select the SubnetVdb tab,. 2 Click on the Search button to bring up the Subnet vDB inventory database. See “Searching the Subnet vDB” on page 4-33. 3 Modify the Subnet vDB to map IP subnets to VLANs. See “Modifying the Subnet” on page 4-34.
4-34 CHAPTER 4: NETWORK CONFIGURATION TASKS ■ Select Search. Once the parameters appear in the display section you can edit or modify the database. Modifying the Subnet To modify the SubnetvDB: 1 Select a row. 2 Use the bottom portion of the dialog box to edit parameters. 3 Select Replace. A warning message appears if you try to modify the database while in Search mode. To add or delete database parameters: 1 Select a row. 2 Edit the parameters. 3 Click Add or Delete.

5 NETWORK MODIFICATION TASKS This chapter describes how to perform the following ATM and VLAN Management network modification tasks.
5-2 CHAPTER 5: NETWORK MODIFICATION TASKS Several methods are provided for moving Ethernet segments between VLANs. They are detailed in the following sections. ■ Using the VLAN Move Operation ■ Drag-and-Drop Ethernet Segments Between VLAN Windows. ■ For the SuperStack II Switch 2700 or CoreBuilder with 7x00 card, see Drag-and-Drop on Front Panel Window. ■ Automatic VLAN Moves Based on Policies. ■ Moving Ports Between Protocol-based VLANs.
VLAN Moves 5-3 To locate Ethernet segments: 1 In the Root window, double click on the Virtual LANs icon or highlight the icon and from the ATMvLAN menu select Zoom Physical. Alternatively, you can descend through the LAN Emulation windows to the LANE User window. See “Using the LAN Emulation Window” on page 5-6. The Virtual LANs Window is displayed as in Figure 5-1. .
5-4 CHAPTER 5: NETWORK MODIFICATION TASKS The VN-vLAN_name window appears as in Figure 5-2, with the Ethernet segments associated with the selected VLAN displayed. Figure 5-2 The VN_name window 3 Reposition the VN-vLAN_name window so that it is separate from the Virtual LANs window. 4 In the VN-vLAN_name window, identify the Ethernet segment icons to be moved by their IP addresses and port numbers.
VLAN Moves 5-5 The port icons, colored brown, are part of the admin VLAN. These icons cannot be moved from the admin VLAN to other VLANs in SuperStack II Switch 2700 or CoreBuilder with the 7X00 card units.These ports can be moved from the admin VLAN to other VLANs in SuperStack II Switch 1000/3000 and Desktop Switches. 6 In the Virtual LANs window, select the destination VLAN. Be certain to press Ctrl/MB1 when selecting the destination VLAN, so that Ethernet segments remain selected in the source window.
5-6 CHAPTER 5: NETWORK MODIFICATION TASKS Using the LAN Emulation Window 1 In the Root window, double click on the LAN Emulation icon or highlight the icon and select the Zoom icon. 2 Double click on the source LANE User or highlight the icon and select the Zoom icon. The LANE User window is displayed with the Ethernet segments associated with the selected VLAN. 3 Proceed with step 4 as described in the previous section.
VLAN Moves 5-7 In the HPOV platform, use CTRL/MB1for multiple selections or select a rectangle over an area to enclose multiple Ethernet segment icons using the drag/MB1 feature. 3 Open the destination window. You do not need to select anything. 4 Using the middle mouse button, drag the Ethernet segment from the source VLAN window to the destination VLAN window and release. The VLAN Move window is displayed. See Figure 5-3.
5-8 CHAPTER 5: NETWORK MODIFICATION TASKS When you toggle on a VLAN name, the lines underneath the ports become the alias color of the VLAN, thus making it easier to identify the ports associated with the VLAN. Figure 5-4 SuperStack II Switch 2700 Front Panel Display 2 Click on the destination Ethernet ports (segments). You can use the drag/MB1 feature to select a rectangle and enclose multiple ports. The selected port’s background is displayed in blue.
VLAN Moves 5-9 Automatic VLAN Moves Based on Policies In addition to the manual VLAN Move method above, devices can be setup to automatically configure themselves into VLANs based on policies. Using this method, ports automatically move between VLANs. The changes are dynamically reflected in the VLAN maps. Policy-based VLAN Auto-configuration is described in detail in Chapter 4.
5-10 CHAPTER 5: NETWORK MODIFICATION TASKS Local VLANs and VLAN Move Local VLANs act as “holding” VLANs in the event that LAN Emulation connectivity is incomplete. Although local VLANs cannot be directly established by the ATMVLAN manager, they can be activated during a VLAN Move operation involving ATM-based VLANs. When Ethernet segments in a device are reassigned to a different VLAN they are detached from the LEC of the old VLAN and attached to the LEC of the new VLAN.
VLAN Moves 5-11 Using the information derived from the snooping procedure, the device then attempts to resolve something based on the policy it is trying to enforce. For example, if the policy is a MAC-based auto-VLAN configuration policy, the device will resolve the MAC address to VLAN mapping using external services where the mapping information is stored. This may result in a query to an external server asking for the VLAN mapping information.
5-12 CHAPTER 5: NETWORK MODIFICATION TASKS VLAN server is deployed in the network. This policy is not supported in this release. ■ IP Subnet based automatic VLAN configuration policy Segments or devices assigned to this policy will automatically be configured into various VLANs based on a predefined IP Subnet address to VLAN mapping. A parameter database called Subnet Vdb must be created and setup using the Locator Tool prior to using this policy.
Enabling and Disabling Ports 5-13 associated to the segment (or another proxy device) will enforce the policy on that device or segment. Figure 5-5 ATM and VLAN Policy Map You can move segments from one policy to another using the same operations as the VLAN Move. See “Moving Ethernet Segments Between VLANs” on page 5-1. For a more detailed description, see “Configuring Policy-based VLAN Auto-configuration” on page 4-24.
5-14 CHAPTER 5: NETWORK MODIFICATION TASKS Manual LECS Database Modification The Manual LANE Redundancy Configuration Assistant is used for manually modifying a specific LECS database, to enable a backup LES, or to re-enable a primary LES when the backup is enabled. This configuration assistant allows the operator to manage manual LANE redundancy. The failed LES is located according to its address by scrolling the ELAN IDs window and the backup LES is activated by clicking on its radio button.
Manual LECS Database Modification 5-15 Each ELAN contains two entries of LES addresses. 5 For each ELAN, select the LES that was not automatically changed. 6 Click Apply to update the database. Manual LANE Redundancy operates on only one LECS at a time. You can select the LECS in the Topology Tool or in the Backbone and Services map. The Automatic LANE redundancy monitor, see page 4-14, must be disabled and then restarted after manually fixing the LECS database.

7-2 CHAPTER 7: NETWORK PERFORMANCE MEASUREMENT TASKS The historical data collected and stored by the NNIx tool can be graphed viewed as line graphs, pie charts and bar graphs. The following sections describe the various components of the NNIx tool as well as how to configure the tool for historical data collection. The NNIx Tool is composed of two windows: the NNIx Browser and the NNIx Map. NNIx Browser The NNIx Browser lists all the ATM switches in the network.
Measuring Network -wide ATM Traffic Performance Using the Bandwidth Icon 7-3 To select a switch for display on the active NNIx Map 1 Click on the ATM Switch entry in the NNIx Browser. 2 Click on the Show (plus) icon. To select a switch hierarchy for display on the active NNIx map 1 Click on the ATM Switch entry in the NNIx Browser. 2 Click on the Show Subtree (double plus) icon. Once the switches are added to the NNIx map, data collection starts automatically.
7-4 CHAPTER 7: NETWORK PERFORMANCE MEASUREMENT TASKS Each ATM switch is displayed as a circular icon which is also a pie chart representing the in and out UNI traffic corresponding to that switch. The upper 1/2 portion of the pie represents the maximum percentage of speed of the out traffic and is colored red.The lower portion of the circle represents the maximum percentage of speed of the in traffic and is colored magenta. The IP address of the switch is labeled below a switch icon.

C An Introduction to ATM and VLAN Management Basics ATM AND VLAN MANAGEMENT BASICS In 1986, the International Telecommunications Union (ITU) formed a study group to explore the concept of a high-speed, integrated network that could uniformly handle voice, data, and a variety of other services. This resulted in BISDN, or the Broadband Integrated Services Digital Network. BISDN services require high-speed channels for transmitting digitized voice, data, video, and multimedia traffic.
C-2 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS ATM Basics ATM uses short, fixed-length packets called cells. The first five bytes of each cell, the header, contain the information necessary to deliver the cell to its destination. The fixed-length cells offer smaller and more predictable switching delays as cell switching is less complex than variable-length packets and can be accomplished in hardware for many cells in parallel.
An Introduction to ATM and VLAN Management Basics C-3 which is typically used to interconnect two ATM switches managed as part of the same network. ■ The UNI is the physical interface between the user and the network. A private UNI consists of a private end-point to private switch interface, whereas a public UNI is typically used to interconnect an ATM user with an ATM switch deployed in a public service provider’s network.
C-4 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS cell with a given connection, and therefore it can be routed to the right destination. Identical VPI/VCI combinations may exist on different interfaces. The VPI is a bundle of VCs. Individual VCs have unique VCI values, but the VCI values may be reused in each VP.
An Introduction to ATM and VLAN Management Basics C-5 example, SNMP). Permanent connections generally remain established for long periods of time. These connections are not dynamically checked and reinitiated. The major features of a PVC include: ■ Connections initiated by network administrator. ■ Connections established and released manually. ■ Long-term duration connections. ■ Both point-to-point and point-to-multipoint connections can be established.
C-6 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS Table C-2 Comparison of SVC and PVC SVC PVC Supported by signaling standard Supported by MIB or other management entity Integrated ATM/Ethernet Switching ATM Backbone Network When Ethernet LANs are connected through a conventional switching hub or backbone, the bandwidth provided is restricted to the data rate of the Ethernet or FDDI technology running on it.
An Introduction to ATM and VLAN Management Basics C-7 In practice, it is not the individual LAN stations that are formed into VLANs but rather the physical Ethernet LANs, called Ethernet segments, that are grouped into VLANs. Thus, all stations on an Ethernet segment will be on the same VLAN. Also, since an Ethernet segment is connected to the network through an Ethernet port in an edge device, the Ethernet port itself is sometimes referred to as a member of the VLAN.
C-8 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS ATM-based VLANs When the enabling technology is ATM, the VLAN is referred to as an ATM-based VLAN. An ATM-based VLAN is built around an ATM network structure called an Emulated LAN. LAN Emulation The main objective of the LAN Emulation (LE) is to enable existing applications to access an ATM network via protocol stacks as if they were operating over traditional LANs.
An Introduction to ATM and VLAN Management Basics C-9 emulated Ethernet service interface to higher level software which implements the LAN Emulation User-to-Network Interface (LUNI). LAN Emulation Configuration Server (LECS) The LAN Emulation Configuration Server implements the assignment of individual LAN Emulation Clients to different emulated LANs. When a LEC initializes, it establishes connection to the LECS.
C-10 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS operate in a Switched Virtual Channel (SVC),Permanent Virtual Channel (PVC), or mixed SVC/PVC environment. Figure C-3 LAN Emulation Components Admin and Default VLANs Two special purpose ATM-based VLANs are established automatically by the system, the Network Administration VLAN and the Default VLAN.
An Introduction to ATM and VLAN Management Basics C-11 the configuration is such, the network manager should ensure that IP connectivity to the device is not affected by VLAN moves. The Default VLAN When an ATM edge device is initialized, a single VLAN called the default VLAN is created automatically and all ports of the device are assigned to it. In the SuperStack II Switch 2700 module, the Admin VLAN is also used as the Default VLAN when the SuperStack II Switch 2700 is first initialized.
C-12 APPENDIX C: ATM AND VLAN MANAGEMENT BASICS Trunk (VLT). A VLT port in one switch unit must be connected only to a VLT port in the second switch unit so that the traffic can be switched to the correct VLAN. Tagging To distinguish between data frames belonging to different VLANS which are sent over a common VLT between two switch units, frame tagging is employed. Each frame which is sent along the VLT is tagged with a VLAN identifier.
Protocol-based vLANS C-13 Table C-1 on Table C-1 lists the protocol suites that the LANplex supports, as well as the protocol types included in each protocol suite. Table C-1 Protocol Suite Protocol Types Protocol Suite Protocol Types IP IP, ARP, RARP Novell IPX IPX AppleTalk DDP, AARP Xerox XNS XNS IDP, XNS Address Translation, XNS Compatibility DECnet DEC MOP, DEC Phase IV, DEC LAT, DEC LAVC SNA SNA Services over Ethernet Banyan VINES Banyan X25 X.
