Understanding ATM-VLANs
An ATM-VLAN spans an ATM network, bridging two or more Ethernet VLANs, using LAN Emulation (LANE). LANE provides connectivity between ATM-attached devices by emulating a LAN over an ATM cloud. It provides:
•Connectivity between ATM-attached stations and LAN-attached stations
•Connectivity between LAN-attached stations across an ATM network
Since LANE connectivity is defined at the MAC layer, upper protocol layer functions of LAN applications can continue unchanged when devices join ATM-VLANs.
An ATM network can support multiple independent ATM-VLANs. End-system membership in any of the ATM-VLANs is independent of the physical location of the end system. This simplifies hardware moves and changes.
In addition, end-stations can move easily from one ATM-VLAN to another regardless of whether the hardware moves. This section contains Interpreting ATM-VLAN Summary Information

Configuring and Managing ATM Networks
Using Topology Services, you can view, configure and manage Asynchronous Transfer Mode (ATM) networks and domains. This section contains:
•Understanding ATM Domains
•Managing ATM Domains
•Using ATM Domains
•Understanding ATM Management Terms
Understanding ATM Domains
An ATM domain is a group of interconnected ATM switches and ATM end-hosts that can be discovered with the Interim Local Management Interface (ILMI) neighbor discovery mechanism, starting at the seed address.
Switches within the ATM network must support AToM MIB, which is used primarily for managing ATM permanent virtual connections (PVCs) and is defined in RFC 1695.
An ATM end-host contains an ATM network interface adapter. Examples of ATM hosts are workstations, routers, data service units (DSUs), LAN switches, and video coder-decoder (CODEC).
ATM switches:
•Accept the incoming cell from an ATM end-point or another ATM switch.
•Read and update the cell header information.
•Switch the cell to an output interface that is toward its destination.
Managing ATM Domains
You can view and monitor ATM domain status in your network. You can also use the LAN Edge network view to display the ATM domains in your network, and use the ATM Domain network views for details about devices in each ATM domain.
To view the ATM Domain:
Step 1 Go to the Topology Services Main Window and double-click Managed Domains.
Step 2 Double-click ATM Domains.
Step 3 Select an ATM domain to view its summary.

Overview of LAN Emulation (LANE)
LAN Emulation (LANE) enables existing applications to access an ATM network as if they were operating over traditional LANs, such as Ethernet or Token Ring. LANE allows LAN users to benefit from ATM without modifying user hardware or software.
End-user hosts on LANs can connect to other end-user hosts on LANs, as well as to ATM-attached servers, routers, and switches.
LANE reconciles the differences between ATM and LAN protocols by masking the connection setup and handshaking functions required by the ATM switch. Basicaaly, LANE bridges LAN traffic across ATM. LANE has specific hardware requirements.
For details, see your switch or router documentation. This section contains:
•Understanding LANE
•Understanding LANE Components
Understanding LANE
ATM is a connection-oriented service, while LAN is a broadcast medium. ATM uses connection-oriented service with point-to-point signaling or multipoint signaling between source and destination devices.
LAN-based protocol suites use connectionless service and broadcasts so that source devices can find one or more destination devices.
Using LANE, LAN broadcasts are emulated as ATM unicasts. LANE emulates a broadcast environment such as IEEE 802.3 Ethernet or 802.5 Token Ring on top of an ATM network that is a point-to-point environment.
Client devices, such as routers, ATM workstations, and LAN switches use LAN Emulation Server (LES) functions to emulate a LAN across ATM.
LANE defines a service interface for network layer protocols that is identical to existing MAC layers. No changes are required to existing upper layer protocols and applications.
Data sent across the ATM network is encapsulated in the appropriate LAN MAC packets. LANE essentially bridges LAN traffic across ATM and defines the operation of an emulated LAN.
LANE does not emulate every particular physical or data-link characteristic. For example, it does not support carrier sense multiple access collision detect (CSMA/CD) for either Ethernet or Token Ring. LANE on the ATM switch router supports only the IP protocol.
LANE can be implemented on the following devices:
•Directly attached ATM end-stations
•Layer 2 devices, such as Catalyst switches or ATM switch routers
•Layer 3 devices, such as routers
Communication among LANE components is ordinarily handled by several types of switched virtual channel circuits (VCCs). Some VCCs are unidirectional; others are bidirectional. Some are point-to-point; others are point-to-multipoint.
•Control direct VCC
The LAN Emulation Client (LEC), as part of its initialization, establishes a bidirectional point-to-point VCC to the LES for sending or receiving control traffic.
The LEC is required to accept control traffic from the LES through this VCC and must maintain the VCC while participating as a member of the emulated LAN.
•Control distribute VCC
The LES may optionally establish a unidirectional VCC back to the LEC for distributing control traffic. Whenever an LES cannot resolve a LAN Emulation Address Resolution Protocol (LE_ARP) request from an LEC, it forwards the request out to the control distribute VCC of the clients in the LAN.
The control distribute VCC enables information from the LES to be received whenever a new MAC address joins the LAN or whenever the LES cannot resolve an LE_ARP request.
•Data direct VCC
After an ATM address has been resolved by an LEC, this bidirectional point-to-point VCC is set up between clients that exchange unicast data traffic. Most client traffic travels via these VCCs.
•Multicast send VCC
The LEC sets up a unidirectional point-to-point VCC to a multicast server. This VCC is used by the LEC to send multicast traffic to the BUS for forwarding out the multicast forward VCC. The LEC also sends out unicast data on this VCC until the LEC resolves the ATM address of a destination.
•Multicast forward VCC
The BUS sets up a unidirectional VCC to the LECs for distributing data from the BUS. This can either be a unidirectional point-to-point or unidirectional point-to-multipoint VCC. Data sent by an LEC over the multicast send VCC is forwarded to all LECs via the multicast forward VCC.
•Configure direct VCC
This is a transient VCC that is established by the LEC to the LAN Emulation Configuration Server (LECS) to obtain the LES ATM address, which controls a particular LAN that the LEC must join.
Understanding LANE Components
LANE is defined on a client-server LAN model, and the following LANE components must be configured for LANE services to be fully functional:
•LE Configuration Server (LECS)—Acts as the registration point for each emulated LAN within the ATM backbone.
•LE Server/Broadcast Server (LES)—Provides the broadcast and multicast forwarding functions.
•LE Clients (LECs)—Provides the connection points within the ATM backbone for each emulated Layer 2 logical network.
These LANE components and the requirements for using them in an ATM network are described in Table 13-4.
Table 13-4 LANE Component Descriptions
Component
|
Description
|
Requirements
|
LE Configuration Server (LECS)
|
Contains the database that determines to which master LE configuration server (LECS) an ATM-VLAN client belongs.
Clients consult the LECS to determine which ATM-VLAN it should join.
The LECS returns the ATM address of the LES for that ATM-VLAN, and also maintains the LES redundancy information.
|
We recommend that you have one master LE configuration server for each ATM domain.
Campus Manager does not support more than one master LE configuration server. However, you can have additional backup LE configuration servers.
|
LE Server (LES) 1
|
Acts as the control center. Provides joining, address resolution, and address registration services to the LE clients in that ATM-VLAN.
Clients can register destination unicast and multicast MAC addresses with the LE server. The LE server also handles LANE Address Resolution Protocol (LE_ARP) requests and responses.
Clients can communicate directly with one another only when they are connected to the same LE server.
|
We recommend that you have one active master combined LE server and broadcast server for each ATM-VLAN.
Multiple LE servers can exist on the same physical ATM network where each server supports a different ATM-VLAN. You can have additional backup LE servers.
|
Broadcast Server (BUS)1
|
Sequences and distributes multicast and broadcast packets and handles unicast flooding.
|
We recommend that you have one active master combined LES and broadcast server for each ATM-VLAN.
You can have additional backup LE servers.
|
LE Client (LEC)
|
Emulates a LAN interface to higher-layer protocols and applications. Forwards data to other LANE clients and performs LANE address-resolution functions.
|
Can be a member of only one ATM-VLAN.
An ATM device can have several LE clients. It can have one client for each ATM-VLAN of which it is a member.
|
Understanding ATM-VLANs
An ATM-VLAN spans an ATM network, bridging two or more Ethernet VLANs using LAN emulation (LANE). LANE provides connectivity between ATM-attached devices by emulating a LAN over an ATM cloud, including the following:
•Connectivity between ATM-attached stations and LAN-attached stations
•Connectivity between LAN-attached stations across an ATM network
As LANE connectivity is defined at the MAC layer, upper protocol layer functions of LAN applications can continue unchanged when the devices join ATM-VLANs.
An ATM network can support multiple independent ATM-VLANs. End-user node membership in any of the ATM-VLANs is independent of the physical location of the end system. This simplifies hardware moves and changes. In addition, end-user nodes can move easily from one ATM-VLAN to another, whether or not the hardware moves.
You can use Topology Services to configure VLANs with LANE services enabled.
Creating ATM-VLANs
You can use Topology Services to add LE servers to your network, and to configure LE servers and config servers in your network. However, LANE clients (LECs) can be created only from the command line interface (CLI) or CiscoView.
If you are using Virtual Trunk Protocol (VTP), LECs are automatically created when Ethernet VLANs are created on some switches.
Configuring LE Servers
You can create or modify the LE server settings for ATM-VLANs in your network. You can add servers to new or existing VLANs, modify or delete servers, and add backup servers. This section contains:
•Adding LE Servers to New VLANs
•Adding LE Servers to Existing VLANs
•Adding Backup LE Servers
•Modifying LE Servers
•Deleting LE Servers

Setting Up Soft Permanent Virtual Connections or Paths
You can set up soft permanent virtual connections (SPVCs) or soft permanent virtual paths (SPVPs) between two end stations in an ATM network, whether they are displayed in the ATM Domain view or not.
You can accomplish this task using either of the following procedures:
•Setting Up SPVCs or SPVPs—Procedure A
•Setting Up SPVCs or SPVPs—Procedure B
The end stations might not be displayed on the ATM Domain summary view for several reasons. For example, they might not support ILMI or they might not be manageable using SNMP. These devices are called Unmanageable End Stations.
Setting Up SPVCs or SPVPs—Procedure A
To set up a soft permanent virtual connection (SPVC) or soft permanent virtual path (SPVP):
Step 1 Go to the Topology Services main window and double-click Managed Domains.
Step 2 Double-click ATM Domains.

This parameter specifies the selected interval between connection retries for setting up SPVC or SPVP.
b. Set up Usage Parameter Control (UPC) values as follows:
–Select either Pass, Tag, or Drop. The default is Pass.
–Turn Packet Discard On or Off. The default is On.
To save the modified SPVC parameters as the default setting, click Save as Default.
Step 7 Either:
•Click the Transmit tab or the Receive tab and select a template from the Templates drop-down list box to fill in all fields.
Or
•Click Select/Edit to open the Traffic Parameters for the Device window.
This window displays all the currently available traffic descriptors on the source (Transmit tab) or destination (Receive tab) device.
See Editing Device Traffic Templates for more details.
For additional information, see Setting Up SPVCs or SPVPs—Procedure B
Information appearing below the Transmit and Receive tabs is linked. If you update or change the information below the Transmit tab, and there are no values specified below the Receive tab, the identical values appear automatically below the Receive tab.
This operation does not duplicate values from the Receive tab to the Transmit tab.
If in Step 7 you clicked Select/Edit, then the Traffic Parameters for Device window is still open. Click a row in the Traffic Parameters table to specify the transmit or receive traffic parameters. Then click OK to save changes and close the window.
When you select a row in the Traffic Parameters table, the values from that row fill in the appropriate fields below the table. See Traffic Parameters table for an explanation of the fields in each traffic parameter row.
Note To modify fields in the Traffic Parameters table, enter the new values and click Add to Device. This adds a new row of parameters.
When you save changes and close the Traffic Parameters for Device window, the saved values from that window fill the appropriate fields in the Create SPVC/SPVP window. Click Apply in the Create SPVC/SPVP window. The configuration request is sent to the source switch.
The SPVC or SPVP setup starts on the originating LightStream 1010 switch. The Create SPVC/SPVP window remains open until a successful message sent by SNMP is received from the LightStream 1010 switch.
Any error messages are displayed in a popup window. If the process does not succeed, refer to the error message for additional information.
Setting Up SPVCs or SPVPs—Procedure B
To set up a soft permanent virtual connection (SPVC) or soft permanent virtual path (SPVP):
Step 1 Go to the the Network Topology window and select the source and destination link or switch.
There are three valid selection possibilities: a pair of ATM switches, a single ATM switch, or two links between ATM end stations.
Step 2 Go to the Topology Services main window and double-click Managed Domains.
Step 3 Double-click ATM Domains.
Step 4 Select an ATM domain.
Step 5 Select View > Display View.

•To set up an SPVC or SPVP between two manageable end stations, select the source and destination links connected to the end stations.
•To set up an SPVC or SPVP between two unmanageable end stations, select the source and destination switch to which the end stations are connected. If the two unmanageable end stations are connected to the same switch, select only that switch.
Select the source first, then select the destination. The order of the source and destination selection is important because the configuration information is sent to the source switch. The ATM address of the destination port is displayed based on the destination selection.
Step 6 Go to the the Network Topology window and select Tools > Create SPVC/SPVP.
The Create SPVC/SPVP window opens.
Step 7 Click the Advanced Parameters arrow to expand the window.
•To set up a soft PVC, select the SPVC radio button.
•To set up a soft PVP, select the SPVP radio button.
The ATM address is automatically filled in to match the destination device/port selected.
If you are configuring an SPVC or SPVP between two unmanageable end stations, you must define the switch ports to which these end stations are connected.
a. Click Select to open the Device/Port Chooser.
b. Select the ports.
c. Click OK to save your selection and then close the Device/Port Chooser.
d. Enter the VPI and VCI values for the SPVC.
Do not enter VPI/VCI values that are already in use. Check the Used VPI/VCIs drop-down list to see if your new values are available.
Step 8 Set the SPVC advanced parameters as follows:
a. Enter the required information in the Max Retry Interval field.
This parameter specifies the selected interval between connection retries for setting up SPVC or SPVP.
b. Set up Usage Parameter Control (UPC) values as follows:
–Select either Pass, Tag, or Drop. The default is Pass.
–Turn Packet Discard On or Off. The default is On.
To save the modified SPVC parameters as the default setting, click Save as Default.
Step 9 You can do either:
•Select a template from the Templates drop-down list box to fill in all fields.
Or
•Click Select/Edit to open the Traffic Parameters for Device window.
This window displays all the currently available traffic descriptors.
If in the preceding step you clicked Select/Edit rather than using the list of Templates, then select one of the traffic parameter columns in the Traffic Parameters for Device window to specify the transmit or receive traffic parameters.
When you select a row, the values from that row fill in the appropriate fields below the table, which explain the meaning of each parameter.
See the Traffic Parameters table for an explanation of the fields in each traffic parameter row.
To modify fields in the Traffic Parameters table, enter the new values and click Add to Device. A new row of parameters is added.
Step 10 Click OK.
The values fill in the Traffic Parameter fields in the SPVC/SPVP window, and the Traffic Parameter Templates window closes.
Step 11 In the Create SPVC/SPVP window, specify the receive traffic parameters by selecting the Receive Traffic Parameters tab.
Information appearing below the Transmit and Receive Traffic Parameters tabs is linked.
If information below the Transmit tab is updated or changed, and there are no values specified below the Receive tab, then the identical values appear automatically below the Receive tab.
This operation does not duplicate values from the Receive tab to the Transmit tab.
Step 12 Repeat Step 12 and Step 12a.
Step 13 Click Apply in the Create SPVC/SPVP window.
The configuration request is sent to the source switch.
The SPVC or SPVP process starts on the originating LightStream 1010 switch. The Create SPVC/SPVP window remains open until a successful message sent by SNMP is received from the LightStream 1010 switch.
Any error messages are displayed in a popup window. If the process does not succeed, refer to the error message for additional information.

Working With Virtual Connections
You can display and monitor virtual connections (VCs) in an ATM network.
Topology Services supports the following:
•The display of all the VCs on a link
•All the VCs between two selected devices
•A particular VC on a link (based on the VPI/VCI pair). This is only when displaying VCs for each device.
Topology Services also supports VC tracing, monitoring of VC utilization and errors, and connectivity checking.
VC tracing can be used to isolate hosts in the network that consume excessive bandwidth. VC tracing provides a topological span of the VC and clarifies node communication destinations.
After the intermittent nodes are identified for a VC under investigation, these nodes can be checked for performance problems or errors.

Step 2 Click Select to select a device.
To create a template based on quality of service (QoS) settings that exist already on the selected device, select those settings in the table, and then enter a name in the Name field.
Otherwise:
a. Select the QoS class from the options in the QoS-Class drop-down list.
b. Enter a template name in the Name field.
Step 3 Enter the values in kilobits for PCR(0+1), SCR(0), MCR, and SCR(0+1). If you supply incorrect values, an alert message explains how to correct them.
Step 4 Enter the CDVT cell time value and the MBS cell value.
Depending on your selection from the QoS-Class drop-down list in Step 3, some of the fields specified in Steps 3 and 4 might be unavailable for text entry.
•To save the template to the database for use with other devices, click Add to Templates.
•To apply the template to the selected device, click Add to Device.
This selection adds a row to the connection traffic table on the specified device.
•To delete a template from a device, select its row in the table and then click Delete from Device.
This selection deletes the row from the table. You cannot delete well-known connection traffic rows, or rows that are in use.
Step 5 Click Delete from Templates if you no longer require this template.
