Monitoring LANE Virtual Connections

This chapter describes features available from the AtmDirector ATM-VLAN topology map that allow you to monitor, trace, and plot real-time information about virtual channel connections among LANE components.

Overview--LANE Virtual Channel Connections

A virtual channel connection (VCC) is a specific instance of a switched virtual circuit (SVC) or permanent virtual circuit (PVC). During call setup and data transfer, ATM-VLANs use the following types of VCCs:

• Configure direct--Establishes an initial connection between client or LE server and configuration server

• Control direct--Used by the client to contact the LE server

• Control distribute--Used by the LE server to communicate with clients

• Multicast send--Used by the client for communication with the broadcaster server

• Multicast forward--Used by the broadcast server to pass broadcast and unknown data to clients

• Data direct--Used between clients for data transfer

Monitoring Control Connections for a LANE Component

The Control Connections window shows all the incoming and outgoing control connections for a LANE component. This window also allows you to access a secondary window for displaying trace reports of the virtual connections in tabular format.

To monitor the control connections for a LANE component, follow these steps:

Step 1 From the AtmDirector main window, double-click on the name of an ATM-VLAN to display the ATM-VLAN topology.

Step 2 Select a client, LE server, configuration server, or broadcast server from the ATM-VLAN topology map.

Step 3 Select the appropriate menu option for the LANE component you selected:

• Tools>Control Connection VCs>Client Connections

• Tools>Control Connection VCs>LE Server Connections

• Tools>Control Connections VCs>Broadcast Server Connections

• Tools>Control Connection VCs>Config Server Connections

The Control Connections window opens for the selected LANE component (Figure 9-1). The information in this window is described in Table 9-1.

Connections are grouped based on the destination LANE component. For example, all the connections between the selected LANE component and its LE server are grouped together.

Step 4 To view a tabular trace report of the VCs, click Trace Report.

For a description of the trace report display, see "Displaying Trace Report in Tabular Form" in Chapter 7, "Managing Virtual Channels."

Step 5 Click OK when you have read the control connections.

Table  9-1: Control Connections Field Descriptions

Field	Description
Selected Component
Host Name	Name of selected host
Type	LANE component type
Interface	Identifier of interface on the host device
VPI	Virtual path identifier for this connection
VCI	Virtual channel identifier for this connection
Peer Host	Device with which the selected host has established this VC
Peer Type	LANE component type of Other Host
Cast	Type of connection: point-to-point, or point-to-multipoint
Conn. Type	Type of this VC: configuration direct, control direct, control distribute, multicast send, multicast forward

Monitoring Data Direct Connections for a Client

The Control Connections window shows the details of all the data direct virtual connections between a selected client and other clients in the same ATM-VLAN. This window also allows you to access a secondary window for displaying trace reports.

To monitor the data direct connections from a client, follow these steps:

Step 1 From the AtmDirector main window, double-click on the name of an ATM-VLAN to display the ATM-VLAN topology.

Step 2 Select a client from the ATM-VLAN topology map.

Step 3 Select Tools>Data Direct VCs.

The Data Connections window opens (Figure 9-2). The information shown in this window is described in Table 9-2.

Step 4 To display a tabular trace report of the VCs, click Trace Report.

For a description of the Trace Report window, see "Displaying Trace Report in Tabular Form" in Chapter 7, "Managing Virtual Channels."

Step 5 Click OK when you have read the data connections.

Table  9-2: Data Connections Field Descriptions

Field	Description
ATM-VLAN Name	Administrative name of the ATM-VLAN to which this client belongs
Selected Client	Name of client for which data connections are shown in this window
Data Direct VCs
Destination Client	Device with which the selected client has established a data connection
VPI	Virtual path identifier for this connection
VCI	Virtual channel identifier for this connection
