This chapter describes the Connection Manager feature. To start the Connection Manager, first start the CWM Desktop from the CWM Main Menu, as described in Chapter 2 "Starting and Stopping Cisco WAN Manager". You click on the CWM Desktop window's Connection Management button to invoke the Connection Manager. The Connection Management window is displayed.
You use the Connection Manager to create and maintain end-to-end connections or Permanent Virtual Circuits (PVCs). A connection consists of a source (localEnd), a destination (remoteEnd) and a set of connection parameters required for the routing.
You use the new Connection Template Manager feature to define a set of parameters so that you can reuse them in Connection Manager to define connections. Templates can be saved to files and then used to create or modify connections.
You can have up to four Connection Manager windows running on your workstation at any one time (though only one can be started from the CWM Desktop; the others must be started from a Connection Manager window's File menu).
Cisco WAN Manager 9.2 supports connections for Frame Relay (FR), Asynchronous Transfer Mode (ATM) both Unicast and ATM-Multicast, Circuit Emulation (CE), Voice, and Data service modules. The following connection types are supported:

To establish a connection, you must first configure the following:
To configure a connection, complete the following steps:
Step 1 Log in to the CWM workstation as a user with access privileges that allow you to create connections using Connection Manager.
Step 2 If necessary, start CWM and launch the desktop.
Step 3 Select Connection Manager.
Step 4 Select a Connection Mode, either Normal or Dial Up.
Step 5 Select a connection type from the list of connections.
Further configuration of your connection depends on the connection type. Follow the directions from one of the following selections:
The following endpoints/cards are supported by the CWM version 9.2 Connection Manager:
The CWM Connection Manager supports two connection modes:
Operations supported in Normal mode:
Operations supported in Dial-Up mode:
Connection types supported in Normal mode:
Connection type supported in Dial-Up Mode:
When you click on the Connection Management button on the CWM Desktop window, the Connection Manager window is displayed.
This window is used to browse the list of established connections, as well as to invoke the other CWM Connection Manager features.
The Connection Manager controls are divided into the following groups:
A separator line between the two portions can be moved up to display the Connection List in a larger pane, by clicking and dragging the small button at the right margin of the separator line.
To populate the Connection List, you must first specify a node using the Connection End Points' Local Information.
You select either the Normal and Dial-Up mode option from the Connection Mode menu.
You click on the connection type(s) to be included in the filter criteria, from the following options: FR-FR, ATM-ATM, ATM-FR, CE-CE, Voice, Data, and ATM-CE. The connection ATM-ATM implicitly includes ATM-RPM and RPM-RPM types of connections. Similarly, the connection ATM-FR includes RPM-FR.
You can filter the Connection List for multiple connection states from the following options: OK, Failed, Down, or Incomplete.
The Multicast Type check boxes allow you to choose from the following options:
When you have made your node and port selections and set the filters as desired, click on the Apply button to display a list of connections in the Connection List pane.
Click on the Reset button to restore the filter conditions to the state they were in at the time you last clicked the Apply button.
You enter a Routing Node and Shelf (feeder) in the Node Name field, or use the "..." button to display the Node:Shelf Selection window. Select a node in the Nodes pane and, optionally, a shelf in the Shelves pane. Click on the OK button. The less specific the information (for example, node only with no shelf), the broader the filter. You can also use the * (asterisk) character as a wildcard for shelf names but not for nodes.
When you want to further refine your selection filter by choosing a port, enter the ID in the Port # field. The port specification is either <slot>.<port> or <slot>.<line>.<port> depending on the endpoint or card type.
Or, click on the "..." button to the right of the field. Select a slot from the Slot pane of the Slot/Port Selection window, and optionally, a logical/physical port from the right pane. Click on the OK button.
Enter the remote endpoint's routing node and shelf name in the Remote Information text field when you want the filter to show only those connections with the specified endpoint.
This pane contains a list of connections which meet the filter criteria (the list is empty until you click on the Apply button). You must select a Connection List entry prior to clicking on the following buttons: Modify, Delete, Associate Backup, Test Connection, and Test Delay.
The pane contains the following columns:
To perform some action on a connection or to edit or delete it, first select a row in the list and then click on a button immediately below the Connection List. Buttons are disabled when inappropriate for the connection you selected.
The Refresh button is always enabled as long as items exist in the list. Click on this button when it turns red, which indicates something in the connection list has changed.
Select a connection in the Connection List, then click on this button to change the parameters which define the connection. The contents of the window that is displayed depends on the type of connection. The Modify Connection window is similar to the New Connection Window, except the data it contains is specific to the selected connection.
Select a connection from the Connection List then click on this button to remove it from the Connection List. Note that, request(s) are sent to the managed network to release the resources allocated for the selected PVC.
Select a connection then click on this button to add or delete an association between a Dial-Backup PVC and a Normal PVC. This option is available only in Dial-Up mode.
Select a connection from the Connection List then click on this button to test the connection and reports the results in the Test Result window. (This button is applicable for connections in Normal Mode only).
Select a connection from the Connection List then click on this button to initiate a Connection Delay test. (This button is applicable for connections in Normal Mode only.)
The Result pane displays the error messages and the results of the attempt to locate connections meeting the conditions you have specified.
Menu options in the Connection Manager window are:
Select this option to start another instance of the Connection Manager program. You can have up to four instances of the Connection Manager running at any one time on a workstation. Only one can be started from the CWM Desktop; the others must be started from the File menu of one of the running programs.
Select this option to exit the Connection Manager. This option works only on the window in which the option is selected. When you have started other Connection Managers, they continue to run.
Select this option to browse multicast connections. This menu item remains disabled when the selected connection is not the correct type for this option.
Select this option to create a new FR-FR connection.
Select this option to display a submenu, which allows you to display a new ATM-ATM Connection window with fields appropriate to one of the following service types:
This submenu is also used to configure RPM-RPM and RPM-ATM connections.
Select this option to display a submenu allowing you to display a New ATM-FR Connection window with fields appropriate to one of the following service types:
This submenu is also used to configure RPM-FR connections.
Select this option to create a new CE-CE connection.
Select this option to create a new Voice connection.
Select this option to create a new Data connection.
Select this option to create a new ATM-CE connection.
New Connection windows for all supported types of connections can be invoked from the Main Window's Configure menu.
The New Connection window consists of fields and controls allowing you to specify local and remote endpoints, and set various endpoint and connection parameters. As different types of connections require different types of parameters to be set, the New Connection window contains different specific controls for different connection types.
However, the window is always similar in structure and functionality. Figure 5-5 shows the "New ATM-ATM Connection Window (for Service Type VBR.3)". The Originating endpoint options are specified in the group of controls in the upper left corner of the window. The Terminating endpoint options are specified in the upper right corner of the window. Controls for specifying Connection Parameters are specified in the lower portion of the window, followed by a Result pane, and the window's action buttons (Apply, Reset, and Cancel).
The Apply button applies the currently specified parameters and options to the connection.
The Reset button restores values in all fields to the state they were in when you last clicked the Apply button (or displayed the window, when you have not yet used the Apply button)
The Cancel button closes this window without taking any action.
Only an endpoint specification is required in order to add a new connection. All other parameters are set with default values according to the endpoint type.
On all variants of this window, specify an originating and a terminating routing node using the Node Name and Port # fields.
To add a connection between two Frame Relay endpoints, select the New FR-FR Connection option from the Connection Manager's Configure menu. A FRASM MGX 8220 card's parameter set is set the same way as a Frame Relay's parameter set, and the same window layout is used for FRASM-SNA endpoints. A FRASM card is an SNA endpoint, but the Connection Manager treats it like any other Frame Relay endpoint.
The New FR-FR Connection window contains the following fields and controls:
The Originating End Point control group contains the following items:
The Terminating End Point control group contains the same fields and controls as the Originating endpoint control group.
The Connection Parameters group of controls contains the following fields/controls:
Note, the routing parameters: Reroute Priority, Preferred Route, Use Trunks Using ZCS, and Avoid Trunk Types are applicable only when a connection involves multiple routing nodes. Routing is not involved when a connection originates and terminates on the same routing node. That is, when originating and terminating endpoints are using the same routing node, these parameters are not applicable and are made insensitive (grayed out).
This group of controls contains the Originating->Terminating and Terminating->Originating parameters, which affect the connection traffic in the directions indicated.
An ATM-ATM connection is one in which both originating and terminating endpoint types are of type ATM.
Several service types are supported for ATM connections. Based on the service type selected, the endpoint and connection parameters displayed in the New ATM-ATM Connection window change. These service types do share some common endpoint and connection parameters, however.
Most of the parameters displayed in the window are applicable to a specific endpoint type.
A read-only field defining the connection type.
A read-only field displaying the service type selected.
This group of controls defines the originating endpoint specification and parameters.
This group of controls defines the terminating endpoint specification and parameters. Fields are identical to those in the Originating endpoint group.
These parameters are applied to the routing segment.
The controls in this group determine parameters for the connection traffic in the direction of originating endpoint to terminating endpoint.
This group of controls defines the terminating endpoint specification and parameters. Fields are identical to those in the Originating endpoint group.

In addition to the fields described previously for an New ATM-ATM Connection window, the following fields are added for an ABR.1 service type connection:
These buttons are located in the Ingress UPC parameters section of the Originating endpoint group. Click on one of the buttons to set traffic policing for the endpoint. This parameter is modifiable only when the Enable VS/VD check box in the Flow Control/Service Parameters control group is enabled.
This button is located in the Flow Control/Service Parameters section of the Connection Parameters group. Virtual Source/Virtual Destination (VS/VD) is used to divide an ABR connection into two or more separately controlled ABR segments. This flag indicates whether or not the ATM two endpoints serves as VS/VD. This option is only applicable when both endpoints are BXM/UXM. For all other connections, this option is disabled. When the Enable VS/VD check box is enabled, the parameters Policing Model, Enable Ext. Segment Flow Ctrl, Nrm, TBE, FRTT, ADTF, and TRM are also enabled.
Click on this button to enable or disable the Flow Control External Segment option, which determines whether or not RM cells are generated when congestion is detected in this connection. This is also referred as BCM. This parameter is modifiable only when Enable VS/VD is enabled.
Use the arrow buttons to change the value of this field. NRM is the maximum number of cells a source may send for each forward RM-cell. Valid values range from 2-256. This parameter is modifiable only when Enable VS/VD is enabled.
Specify the Transient Buffer Exposure (TBE) value. The network uses this number as its goal when negotiating a limit on the number of cells the source sends during start-up periods, before the first RM-cell returns.This parameter is modifiable only when Enable VS/VD is enabled.
Specify the Fixed Round-Trip Time (FRTT) value. The FRTT is the sum of the fixed and propagation delays from the source to a destination and back. This parameter is modifiable only when Enable VS/VD is enabled.
Specify the ACR Decrease Time Factor, which is the time permitted between sending RM-cells before the rate is decreased to ICR. This field is not applicable to MGX 8220 endpoints.
Specify the ForeSight minimum adjustment period, which provides an upper boundary on the time between forward RM-cells for an active source. This field is not applicable to MGX 8220 endpoints.

The Connection Template Manager feature makes using CWM easier by allowing you to setup a set of parameters as templates, and use them in connection configuration.
Connection Template Manager provides an easy way to create connections with non-default parameters. Templates can be created from connection windows or existing connections, saved into files, and re-applied to new connections. CWM supports construction of template data from connections, populating template parameters into connection windows, and type checking between connection types and the applied templates.
All parameters in the Connection Manager windows are supported by Connection Template Manager feature.
You can create default templates for ATM-ATM, FR-FR, ATM-FR, CE, Voice, and Data connections for a given class of service on a per-endpoint type. The selected service type/endpoint type template file is used to populate the parameters in the connection window during connection creation.
You can invoke Connection Template Manager from:
Template files are located in the /usr/users/svplus/templates directory and placed in the appropriate service type subdirectory. For example, for ATM-ATM with VBR.3 service, the directory is /usr/users/svplus/templates/ATM-ATM/VBR.3.
The subdirectories under /templates are: ATM-ATM, ATM-FR, CE-CE, DATA, FR-FR, and VOICE. The subdirectories under ATM-FR are ABR.FS and VBR which are the service types supported for ATM-FR. If you create a template for ATM-ATM with VBR.3 service, for example, the directory is /usr/users/svplus/templates/ATM-ATM/VBR.3.
Use a filter to specify which directory you would like to examine.
Use this pane to specify which directory you would like to examine.
Use this pane to specify which file you which to examine.
This pane indicates the full path of the file you wish to examine.
Menu options in the Template File Manager window are:
Select a file from the file list, then click on Load button to apply a template file to a new connection. Template Manager first validates the compatibility of the template file with the connection window. A template file is compatible with a connection window if it has the same release number, service type, and endpoint type as the new connection window. If any of these is incompatible, you get an error message. If it passes the compatibility match, then parameter name matching verifies each and every parameter name. In case of any mismatch, you get an error message.
To create a template file from a connection window, you enter the file name to be created in the Selection text, then click on Create button. When the create button is clicked the Template Manager performs the following tasks:
The template file is created with read-only permission.
Select a file from the file list, then click on View button to view a template file. You then get a pop-up File Viewer Window as shown in File Viewer Window Figure 5-7.
Select a file from the file list, then click on Delete button to delete a template file. You then get a Question Dialog box confirming that you want to delete the file.
Click on the Filter button to get a list of template files based on the filter you specify.
Click on the Cancel button to close the Template Manager.
To modify an existing connection, select it in the Connection List of the Connection Manager window, then click on the Modify button. The Modify Connection Window is displayed, as shown in Figure 5-8.
The Modify Connection window fields are the same as the New Connection window, except for the following differences:
All of the connection segments that make up the entire connection are displayed in this field.
The format is:
<local-endpt><intermediate-endpoint1>,
<intermediate-endpoint2><remote-endpt>
The current connection route is displayed in this field.
The format is:
<node name> [<out trunk> -- <in trunk> <node name>]
The parameters within the square brackets may be repeated up to nine times. This field is not editable.
Click on this button to display the Configure Preferred Route Window (used to specify the preferred route path). Only routes for intra-domain connections may be specified; the network does not support preferred routes of inter-domain connections.
This field is not editable in the Modify Connections window; it can only be set before the connection has been added to the network.
This field is not editable in the Modify Connections window; it can only be set before the connection has been added to the network.
Multicast connections are used to transmit data from a single source to multiple destinations. This feature consists of two components; a Root endpoint and one or more leaf endpoints. All data terminated on the root endpoint is automatically transmitted through the leaf endpoints.
For example, assume there is a connection between endpoints <A> and <B>, where <B> is the Root endpoint. Two connections are created; <B1> to <C1> and <B2> to <C2>, where <B1> and <B2> are Leaves to endpoint <B>. Any data transmitted to endpoint <A> is multicast to endpoints <C1> and <C2>. Note that <A>, <C1>, and <C2> can be any endpoint types that are supported by the Connection Manager. This multicast feature is only supported on the BPX 8600 - BME 2 port card. When a Root endpoint is created on port1, the corresponding Leaves can only be created on port2 and vice versa. A Root endpoint always takes the VCI as 0, and the Leaves take the Virtual Channel Identifier (VCI) values starting from 1. The binding between the Root and Leaves is done through the common Virtual Path Identifier (VPI).
The multicast connections are added using the regular New Connection windows which are invoked through the Connection Manager window's Configure menu.
As BME is an ATM card, only ATM endpoints can be created as Root or Leaf endpoints. The Multicast Type button is used to make the selection a Normal, Root, or Leaf endpoint.
Other than selecting the multicast type, adding a multicast connection is done in the same way as adding a normal connection.
You display these connections in the Connection Manager window's Connection List by selecting the desired multicast type. For a multicast connection, the value shown in the Type column in the Connection List is appended with either (Rt) or (Lf) indicating a Root or Leaf endpoint.
You can use the Connection Manager to find the links between the Root and Leaves. The Connection Manger can display the Leaves for a given Root, and Root for a given Leaf. Select the desired connection from the Connection List then select the View menu's View Multicast Connections option.
The ANI field is a 20 character numeric field. It is selected from the window displayed when you click on the "..." button. When you select an ANI, all connections defined on the INS server for the selected ANI, are displayed.
The Connection Manager window's Connection List display is changed in "Dial-Up" mode. A connection status of Active or Inactive is displayed in the Status column in the Connection List. Active INS connections cannot be modified. Only inactive connections can be modified by clicking on the Modify button, or deleted by clicking on the Delete button in the Connection Manager window.
To add a new Dial-Up connection to an ANI, click on the New button.
Use this window to set parameters for a new Dial-Up connection.
