Configuring ATM > Creating an NBMA Interface

Creating an NBMA Interface

The NMC-RX software supports nonbroadcast multiaccess (NBMA) networks only on E-series OC3-4 and OC12 line modules.

Six general steps are involved in creating an NBMA interface:

• Create a map list.
• Create map list entries.
• Assign a map list to the ATM interface.
• Create an NBMA interface.
• Create ATM circuits on the NBMA interface.
• Create an IP address on the NBMA interface (see NMC-RX User Guide, Vol. 2, Chapter 6, Configuring IP).

Creating a Map List

To create a map list:

1. From the Device-wide Explorer, click the System folder.
2. Right-click, select Create, and click Map List.

The Create Map List dialog box appears.

3. Type a map list name (1-32 characters), and click OK.

The map list is created.

NOTE: Map lists cannot be modified or viewed. A map list cannot be deleted if it is associated with an ATM interface.

Creating a Map List Entry

After you create a map list, you can add map list entries to it. Map list entries are used to route traffic for an IP address through a circuit by specifying the virtual circuit descriptor (VCD).

To create map list entries:

1. In the Device-wide Explorer, select Map List from the System folder, right-click, and select List.

Map lists are displayed in the list area.

2. In the list area, select a map list to which you want to add a map list entry.
3. Right-click, select Create, and click Map List Entry.

The Create Map List Entry dialog box appears.

4. Set the map list entry parameters (Table 55).

 Table 55:  Map List Entry Parameters 

 Parameter
 Description

 ATM Circuit VCD

 Circuit identifier. Must be unique within the map list. Identifies a VC configured on an ATM interface. 
 Enter a value in the range of 1-4294967295, or click 
to view and select an existing VCD from the Selected VCD Address dialog box (see Related Dialog Boxes).


 IP Address

 Destination IP address associated with the VCD. Enter a valid address, or click 
to search for and select an IP address in the Select IP Address dialog box (see Related Dialog Boxes).


 Broadcast

 Enables broadcast support



 

5. Click OK.
6. (Optional) Assign the map list to an ATM interface. See Table 53 on 200.

Related Dialog Boxes

ATM Circuit VCD

The Select VCD Address dialog box appears when you click next to the ATM Circuit VCD field in the Create Map List Entry dialog box. Use it to view and select an existing VCD.

1. Click an available ATM VCD.
2. (Optional) Click View to display the circuit's full configuration.
3. Click OK.

The information is entered in the Create Map List Entry dialog box.

IP Address

The Select IP Address dialog box appears when you click next to the ATM Circuit VCD field in the Create Map List Entry dialog box. Use it to search for and select an IP address.

1. Select a search option, and click List.
2. Select a virtual router from the list. If the virtual router has been assigned IP addresses, the addresses are displayed below.
3. Select an IP address.
4. Click OK.

The information is entered in the Create Map List Entry dialog box.

Creating an NBMA Interface

 NOTE: The NMC-RX software supports NBMA only on E-series OC3-4 and OC12 line modules. 



 

To create an NBMA interface:

1. Navigate to the ATM interface for which you want to create an NBMA subinterface.
2. With the ATM interface selected, right-click, select Create, and click NBMA Interface.

The Create NBMA Interface dialog box appears.

3. Enter a name in the Sub Interface Name text box, and include a description, if needed.
4. Click OK.
   

   NOTE: You can create multiple ATM circuits (see 211) and IP addresses (see NMC-RX User Guide, Vol. 2, Chapter 6, Configuring IP) on the NBMA interface.
