Creating Frame Relay Objects

This section provides procedures for creating Frame Relay objects. The procedures are presented in the order in which you would typically perform them: Create an interface first, a subinterface next, and then a circuit.

NOTE: The following procedures apply to configuring Frame Relay on channelized modules. If you are configuring Frame Relay on an unchannelized module, you configure it from the line interface level.

Creating Frame Relay Interfaces

After you have configured a DS0 bundle (see Chapter 13, Configuring DS0 Bundles), you are ready to create Frame Relay interfaces.

NOTE: Only one Frame Relay interface is allowed per DS0 bundle.

To create a Frame Relay interface:

1. In the Instance Explorer, select the module for which you want to configure a Frame Relay interface.

The line interfaces appear.

2. Double-click the line interface.

The DS1 interfaces appear.

NOTE: If you are configuring a CT3 module, double-click a line interface to display the DS1 interfaces.

3. Double-click a DS1 interface.

The DS0 bundles appear.

4. Select a DS0 bundle, right-click, select Create, and click Frame Relay.

The Create Frame Relay Interface dialog box appears.

5. Set the Frame Relay interface parameters (Table 69).

 Table 69:  Frame Relay Interface Parameters  

 Parameter
 Description

 Name

 Identifies the interface; generated automatically


 Alias

 Description of the interface; 0-15 characters; default: blank


 IfIndex

 Identifies the interface on the particular line interface; generated automatically


 Operational

 Current operational status of the interface


 Administrative

 Desired status of the interface: Up/Down; default: Up


 Interface Type


  
 Data communication equipment (DCE)
  
 Data terminal equipment (DTE)
  
 Network-to-Network Interface (NNI)



 Interface State

 Sets local management information (LMI), which provides configuration and status information relating to the virtual circuit running over Frame Relay; options: None, ANSI, Cisco, Q.933


 Multicast

 Indicates whether this virtual circuit is used as a unicast virtual circuit or the type of multicast service being used. Currently, nonbroadcast is the only supported option.


 Monitored Events

 Diagnostic window used to verify link integrity; not available when none is selected from Interface State; range 1-10


 Enquiry Interval

 Number of status enquiry intervals that pass before issuance of a full-status enquiry message; enquiry interval is applicable to DTE and NNI only; not available when none is selected from Interface State; range 1-255; default 6


 Address Format

 Address format that is in use on the Frame Relay interface. Currently, Q922 is the only option.


 Address Length

 Address length in octets


 Poll Interval (sec)

 Number of seconds between successive status enquiry messages; not available when none is selected from Interface State; range 5-30 seconds


 Error Threshold

 Number of errors that will take the interface down; not available when none is selected from Interface State; range 1-10



 

6. Click OK.

The name of the new Frame Relay interface appears in the Instance Explorer below the DS0 bundle.

 NOTE: If there is an applicable template, you can use that template to configure the non-unique parameters for Frame Relay. The non-unique parameters are displayed in blue in a template. For more information, see Chapter 9, Using Templates.



 

Creating Frame Relay Subinterfaces

After you have created a Frame Relay interface, you can create Frame Relay subinterfaces.

To create a Frame Relay subinterface:

1. Click the Frame Relay interface.
2. Right-click, select Create, and click Frame Relay Subinterface.

The Create Frame Relay Subinterface dialog box appears.

3. Set the parameters (Table 70).

 Table 70:  Frame Relay Subinterface Parameters 

 Parameter
 Description

 Name

 Identifies the interface; generated automatically


 Alias

 Description of the interface; 0-15 characters; default: blank


 IfIndex

 Identifies the interface on the particular line interface; generated automatically


 Operational

 Current operational status of the interface


 Administrative

 Desired status of the interface: Up, Down; default: Up



 

4. Click OK.

The name of the new Frame Relay subinterface appears in the list area.

Creating Frame Relay Circuits

The last step in configuring Frame Relay is to create Frame Relay circuits.

To create a Frame Relay circuit:

1. From the list of subinterfaces in the list area, select the subinterface for which you want to create a circuit.
2. Right-click, select Create, and click Frame Relay Circuit.

The Create Frame Relay Circuit dialog box appears.

3. Set the Frame Relay circuit parameters (Table 71). You must assign a unique data-link connection identifier (DLCI) value.

 Table 71:  Frame Relay Circuit Parameters  

 Parameter
 Description

 Logical Name

 Name that identifies the interface


 DLCI

 Data-link connection identifier; mandatory parameter that indicates RFC1490 encapsulation; range 16-1007


 Interface Index

 Interface index number of the Frame Relay subinterface to which the circuit is associated; generated automatically


 Multicast

 Indicates whether this virtual circuit is used as a unicast virtual circuit or the type of multicast service being used



 

4. Click OK.

The new circuit does not appear in the Instance Explorer, but can be displayed if you select the subinterface it was created from and use the List All command.
