Connection Management

Overview

This chapter describes the Connection Manager feature of StrataView Plus (SV+). To start the Connection Manager, first start the Cisco SV+ Desktop from the SV+ Main Menu, as described in Chapter 1 "Cisco StrataView Plus Start-up". You click on the SV+ 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 can have up to four Connection Manager windows running on your workstation at any one time (though only one can be started from the Cisco SV+ Desktop; the others must be started from a Connection Manager window's File menu).

  • Connection Mode

  • Connection Type

  • Connection Status

  • Multicast Type

  • Connection End Points

  • Apply button

  • Reset button

• The Connection List controls contains these elements:

  • The Connection List pane (with column headings Local End, Remote End, Type, and Status)

  • Refresh button

  • Modify button

  • Delete button

  • Associate Backup button

  • Test Connection button

  • Test Delay button

• The Result pane is used to display status and error messages.

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 controls.

Connection Mode

You select either the Normal and Dial-Up mode option from the Connection Mode menu.

Connection Type

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, and Data.

Connection Status

You can filter the Connection List for multiple connection states from the following options: Ok, Failed, Down, or Incomplete.

Multicast Type

The Multicast Type check boxes allow you to choose from the following options:

• Normal---connections with no multicast capability

• Root---connections which have a multicast Root end point

• Leaf---connections which have a multicast Leaf end point

Apply Button

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.

Reset Button

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.

Node Name

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 (not for nodes).

Port #

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 end point 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.

Remote Information

Enter the remote end point'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 end point.

Connection List

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:

• Local End---the connection's local end point. Both local and remote ends are displayed in one of the following formats:

  • Single line Data and Voice end points:

  <routingNode>.[<feederNode>.]<slot>.<port>
  

  • CESM end points and multi-line Data, Voice end points:

  <routingNode>.[<feederNode>.]<slot>.<line>.<port>
  

  • Frame Relay end points when IPX and IGX cards:

  <routingNode>.[<feederNode>.]<slot>.<port>.<DLCI>
  

  • Frame Relay end points of AXIS cards:

  <routingNode>.[<feederNode>.]<slot>.<line>.<port>.<DLCI>
  

  • ATM end points:

  <routingNode>.[<feederNode>.]<slot>.<port>.<VPI>.<VCI>
  

  • Incomplete connections:

  <routingNode>.UNKNOWN
  

• Remote End---the connection's remote end point. The end point is displayed in one of the formats defined for Local End, or the following (used for Remote End only):

  • Unknown remote end:

  UNKNOWN
  

• Type---connection type (FR-FR, ATM-ATM, ATM-FR, CE-CE, Voice, or Data)

• Status---status of the connection (ok, failed, down, or incomplete) at the time the Connection List was generated.

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.

Refresh Button

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.

Modify Button

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.

Delete Button

Select a connection from the Connection List then click on this button to remove it from the Connection List.

Associate Backup Button

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).

Test Delay Button

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.)

Result Pane

The Result pane displays the error messages and the results of the attempt to locate connections meeting the conditions you have specified.

Connection Manager Window Menus

Menu options in the Connection Manager window are:

File - New Connection Manager

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 Cisco SV+ Desktop; the others must be started from the File menu of one of the running programs.

File - Exit

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.

View - View Multicast Connections

Select this option to browse multicast connections. This menu item remains disabled when the selected connection is not the correct type for this option.

Configure - New FR-FR Connection

Select this option to create a new FR-FR connection.

Configure - New ATM-ATM 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:

• CBR.1

• VBR.1

• VBR.2

• VBR.3

• ABR.FS

• ABR.1

• UBR.1

• UBR.2

Configure - New ATM-FR Connection

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:

• VBR.3

• ABR.FS

Configure - New CE-CE Connection

Select this option to create a new CE-CE connection.

Configure - New Voice Connection

Select this option to create a new Voice connection.

Configure - New Data Connection

Select this option to create a new Data connection.

New Connection Window

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 end points, and set various end point 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 6-5 shows the New ATM-ATM Connection Window (for Service Type ABR.FS). The Originating End-Point options are specified in the group of controls in the upper left corner of the window. The Terminating End-Point 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 end-point specification is required in order to add a new connection. All other parameters are set with default values according to the end point type.

New FR-FR Connection

To add a connection between two Frame Relay end points, select the New FR-FR Connection option from the Connection Manager's Configure menu. (As a FRASM AXIS card's parameter set is exactly the same as a Frame Relay's parameter set, the same window layout is used for FRASM-SNA end points. Basically FRASM is an SNA end point, but the Connection Manager treats it like any other Frame Relay end point.)

The New FR-FR Connection window contains the following fields and controls:

Originating End-Point

The Originating End Point control group contains the following items:

• Port type---click on this button to display the following types and select one:

Terminating->Originating

The controls in this group set parameters for the connection traffic in the direction of terminating end point to originating end point.

• Utilization(%)---specify the percentage of channel bandwidth utilization.

ATM-ATM ABR.1 Connection

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:

Policing Model

These buttons are located in the Ingress UPC parameters section of the Originating End-Point group. Click on one of the buttons to set traffic policing for the end point. This parameter is modifiable only when the Enable VS/VD check box in the Flow Control/Service Parameters control group is enabled.

Enable VS/VD

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 end points serves as VS/VD. This option is only applicable when both end points 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 Nrm Flow Ctrl, TBE, FRTT, ADTF and TRM are also enabled.

Enable Ext. Segment Flow Ctrl

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.

NRM

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.

TBE

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.

FRTT

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.

ADTF

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 AXIS end points.

TRM

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 AXIS end points.

End Point Parameters

The ASI, BXM, and AUSM end-point parameters for ABR.1 connections are provided in Table 6-6 and Table 6-7.

ATM-ATM UBR.1 and UBR.2 Connections

This section describes the parameters not previously described in earlier sections on CBR.1, VBR.x, and ABR.FS connections.

No new end-point parameters (originating and terminating) are introduced for UBR.x. The PCR0+1 and CDVT0+1 parameters are identical to the ones in the CBR.1 connection.

No new connection parameters are introduced for UBR.x. The Utilization and PCR parameters are identical to those in a CBR.1 connection.

ASI, BXM, and AUSM end-point parameters for UBR.x connections are provided in Table 6-8 and Table 6-9.

New ATM-FR Connections

An ATM-FR connection is the one that has an ATM end point on one end and a Frame Relay end point on the other. It supports two service types, ABR.FS and VBR.3.

Originating and Terminating End-Point

The Originating and Terminating End-Point control groups alternate between ATM and Frame Relay.

When the New ATM-FR Connection window is displayed for the first time, the originating end point is set to Frame Relay. You can swap the Frame Relay and ATM end point positions by using the End point type button.

• End point type--- click on this button to choose the type of originating end-point, or the type of terminating end point. When the Originating end-point is set to Frame Relay, the terminating end-point is ATM and the End-point type button is used for setting Multicast Type (either Normal, Root, or Leaf). When you choose ATM as the originating end-point, the originating End-point type button becomes the Multicast type button, and the Terminating End Point is automatically set to Frame Relay.

The remainder of the fields and controls in each of these groups are described in the New ATM-ATM Connection and New FR-FR Connection sections of this document.

New CE-CE Connections

A Circuit Emulation connection is supported on the AXIS CESM card. Only the CBR.1 service type is supported.

To pass traffic properly in a CE-CE connection, the port speed, line type, and port type of the local end point must match those of the remote end point.

Specify the following parameters for both Originating and Terminating End Points.

where:
<slot>: (3-32),
<line>: (1-2),
<chanl>: When the CDP is configured as CAS, the valid values range from 1-15 and 17-31 (channel 16 is reserved). For CCS, the valid values range from 1-31.

The Node Help, and Tab key validation remain the same as in the previous release of Cisco SV+. The SlotPort Help window displays slots on which you can create voice connections. You must manually enter the channel number after you click on the Apply button.

The Connection Manager supports voice connections across a tiered IGX/BPX network. The connection types supported are shown in the following table.

The voice parameters are shown in the following table:

The following features have been added:

• In the New Connection window, the Rate Type field for the "local" side is tied to the "remote" side, but not vice versa. For example, when you specify a local rate type value, the same value is automatically placed on the remote side. However, when you want to assign different rate type values to the local and remote ends, you can specifically change the remote Rate Type value.

After you click on the Apply button in the New Connection window, when the Rate Type value is different for the local and remote sides, a warning message is displayed alerting you to respond. Choose to add the connection or cancel the add operation.

• In the Modify Connection window, no relationship between the local and remote side Rate Type parameters exists.

After you click on the Apply in Modify Connection window, when the Rate Type value is different for the local and remote sides, a warning message is displayed alerting you to respond. Choose to modify the connection or cancel the modify operation.

• For a one segment voice and data connection, the remote parameter is not used.

After you click on the Apply in the New window, when the Rate Type value is different for the local and remote sides, a warning message is displayed alerting you to respond. Choose to add the connection or cancel the add operation.

This functionality is not available from the service agent side.

New Data Connection

The Channel Number field for data connections has the following syntax:

<slot>.[<line>.]<chanl>

where:

<slot>: (3-32)
<line>: (1-2)
<chanl>: When the CDP is configured as CAS, the valid values range from 1-15 and 17-31. For CCS, 1-31.

The Node Help and Tab key validation remains the same as in the previous release of Cisco SV+. The SlotPort Help window displays slots on which you can create data connections. You must manually enter the channel number after you click on the Apply button.

The Connection Manager supports data connection across the tiered IGX/BPX network. The connection types supported are shown in the following table:

For a standard rate data connection, specify the data rate in the text field, or use the arrow keys. Each click increases/decreases the data rate to the next supported value. Press without releasing the arrow keys enters the fast increase/decrease mode.

The Sample Per Packet field is enabled only for the standard rate. It specifies the number of samples per packet for the connection rate that supports partially-filled packets. The valid values depend on the data rate you select.

	two-bytes: 12, 18, 24, 32, 36
	four-bytes: 24, 32, 36, 48, 64, 72
	five-bytes: 32, 36, 48, 64, 72
	ten-bytes: 48, 64, 72, 80, 96, 120, 128, 144
 

Fast EIA Enable is enabled only for standard rate connections.

Modify Connection Window

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.

The Modify Connection window fields are the same as the New Connection window, except for the following differences:

Connection Segments

All of the connection segments that make up the entire connection are displayed in this field.

The format is:

<local-endpt><intermediate-end point1>,
<intermediate-end point2><remote-endpt>

Current Route

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.

Preferred Route

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.

Use Trunks Using ZCS

This field is not editable in the Modify Connections window; it can only be set before the connection has been added to the network.

Avoid Trunk Types

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

Multicast connections are used to transmit data from a single source to multiple destinations. This feature consists of two components; a Root end point and one or more leaf end points. All data terminated on the root end point is automatically transmitted through the leaf end points.

For example, assume there is a connection between end points <A> and <B>, where <B> is the Root end point. Two connections are created; <B1> to <C1> and <B2> to <C2>, where <B1> and <B2> are Leaves to end point <B>. Any data transmitted to end point <A> is multicast to end points <C1> and <C2>. Note that <A>, <C1>, and <C2> can be any end point types that are supported by the Connection Manager. This multicast feature is only supported on the BPX - BME 2 port card. When a Root end point is created on port1, the corresponding Leaves can only be created on port2 and vice versa. A Root end point 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).

Adding Multicast Connection

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 end points can be created as Root or Leaf end points. The Multicast Type button is used to make the selection a Normal, Root, or Leaf end point.

Other than selecting the multicast type, adding a multicast connection is done in the same way as adding a normal connection.

Viewing Multicast Connections

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 end point.

Viewing the links between Root and Leaves

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.

Dial-Up Connection Mode

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.

l

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.

Adding a New Dial-Up Connection

To add a new Dial-Up connection to an ANI, click on the New button.

Associate Dial Back-Up Window

When you select a connection in the Connection Manager window, the Associate Dial Back-Up window is displayed.

The Associated to PVC? column indicates whether or not an association already exists. When the selected Normal PVC is already associated with a Dial-Backup PVC, the Display fields at the top of the window are updated to indicated which ANI, and which Dial-Backup PVC, is associated with this Normal PVC. Click on the Delete button to remove the association. You can then select a Dial-Backup PVC and click on the Add button it to create a new association. Only Dial-Backup PVCs having no association to a PVC can be selected for association. The Dial-Backup ANI can never have more than five Dial-Backup PVCs.
