Connection Management

Connection Management

Overview

Use the StrataView Plus Connection Manager to create and maintain end-to-end Frame Relay and ATM connections. Frame relay connections include dial-up and dial backup connections when the network is enhanced with the Intelligent Network Server (INS) Dial-Up Frame Relay application. Parameters that you define at the Connection Manager Window are validated and sent to either the INS server or Connection Manager server.


Note INS Dial-Up and Dial-Backup connections are not physically added to a frame relay network until an INS user dials into the network. Even though they are configured by the StrataView Plus Connection Manager, these connections are considered dormant until they are needed. The INS DAS Server Shelf Installation Manual and the INS Dial-Up Frame Relay Operations Guide provide detailed information about instating and configuring the INS Dial-Up Frame Relay application, and includes instructions for using the Connection Manager.

You can open up to four Connection Manager windows at a SV+ desktop.

Configuration Management

The Connection Manager Window presents updated status information as dependent on the Connection Mode selected at the Main Window. Connection Modes are either Normal Mode or Dial-Up Mode. Normal Mode presents standard Frame Relay and ATM Connections (PVCs), and Dial-up Mode presents INS Dial-up and Dial-Backup connections (PVCs).

The Connection Manager Windows

Connection Manager Main Window

Use this window to configure end-to-end frame relay, ATM, CE - CE, Voice and Data connections. See Figure 7-1 and Figure 7-2 for the Connection Manager Main Window and its Menu.

This release of StrataView Plus allows you to add. delete, modify, or view voice and data connections.


Figure 7-1: Connection Manager: Main Window



The pulldown menu in Figure 7-2 shows the connections you can configure from the Connection Manager Main window. The Voice and Data connections are different from Frame Relay and ATM connections in that certain parameters for voice/data are associated with channel rather than connection.


Figure 7-2: Associate Dial Back-up Window

Dial-Up Connection Mode

The ANI field is a 20 character numeric field. It is selected from a listbox that is popped up when the "..." button is depressed. When an ANI is selected, all of the connections defined on the INS server for the selected ANI are displayed.


Figure 7-3:

Connection Manager: Dial-Up Model

The Main Window connection list display is changed in "Dial-Up" mode, with a connection Status of Active or Inactive in the connection(s) listbox field. Active INS connections cannot be modified. Only connections that are Inactive can be further modified via the main window Modify button or deleted with the Delete button.

Adding a new Dial-Up Connection

To add a new Dial-Up connection to an ANI, select the New button to begin addition of a new connection.


Note ANIs are configured through the INS Server GUI which is invoked through the StrataView Plus Admin GUI.

Use this window to set parameters for a new dial-up connection.

Menu: Connection Manager - Configure Menu

In this section, we will focus on how to add a connection. Figure 7-7 shows an example of the Configure Menu window.


Figure 7-6: Connection Manager: Configure Menu



Specific screens listed in Figure 7-7 show the following types of connections:

Connection type--This section allows the user to specify the connection type further. For example for ATM-ATM, and ATM-FR connections the service type specification will be displayed here.

Originating/Terminating end-point definition--This section provides for the specification of the originating/terminating end-point. A user can choose an end-point type of ATM or Frame Relay. Different fields will be displayed for defining the end-point depending on the end-point type and the end-point card type. The end-point card type is automatically determined by the GUI.

An end-point is defined by its end-point type and its node, [shelf], slot, [line], port, and [channel] information. Examples of specific terminating end-point definitions are as follows:

The prompt for end-point definition has changed from the prompt used in Release 8.1. Instead of prompting for Node name, Interface Shelf, Slot, Line, and Port, you will be prompted for Node Name where Node Name will be in the form <Node Name.Shelf Name> and Port number will be in the form <slot#.logical port#>. A logical port number is defined to be unique across a given slot.

Physical port was used in release 8.1 while logical port is used in release 8.2.

As an example; in order to represent node bpx01, shelf axis01, slot 5, line 1, physical port 1, logical port 10, dlci 100, for Release 8.1 you would enter:

bpx01    axis01    5    1    1    100

but in Release 8.2 you would enter:

bpx01.axis01    5.10    100.

Based on the end-point type appropriate Originating/Terminating end-point parameters are displayed in the region just below this one.

ATM-ATM Connection

An ATM-ATM connection is one in which both originating and terminating end-point types are ATM.

Several different service types (for example, CBR.1, VBR.x, ABR.FS, and UBR.x) are supported for ATM connections. Based on the service type selected, the end-point and connection parameters are changed. Parameters that are common across the different screens are only described on the first screen that they are shown in.

Both ASI and AUSM end-points have the same parameters, the range and default values are different for the 2 end-point types. For each service type the range and default values for all relevant parameters are shown.


Note The Connection Manager GUI supports both VPC and VCC connections. For VPC connections the VCI value is specified as a '*'.

ATM-ATM CBR.1 Connection

Figure 7-10 shows the parameters required to add a CBR.1 ATM connection. In this case, from the users perspective both ASI and AUSM end-points have the same parameters. The ranges and default values that are valid for the two end-point types are listed in this section. Additional end-point and connection parameters required by the network elements (BPX, AXIS) and not shown on the screen will be set automatically by Connection Manager Daemon.

FRSM end-points support both service interworking and network interworking options. In the case of FRP end-points only network interworking is possible.

The option menu for the end-point type in both the originating and terminating end-point sections allow values of Frame Relay and ATM. The only restriction is that if ATM is specified in one end-point then Frame Relay must be specified in the other.

An originating FRSM end-point and a terminating AUSM end-point are given for an ABR.FS connection. The AUSM ABR.FS parameters are the same as those discussed earlier. The FRSM end-point supports the following additional parameters:
