Inter-Node Data Links

This chapter describes the creation of an inter-node data link (INDL) between a local Cisco 6732 node and a remote Cisco 6705 node. An INDL allows the provisioning of a remote node over an established ("nailed-up") connection to the local node.

The provisioning of an INDL requires one node to be designated the local node, and another node designated the remote node. In this example, the Cisco 6732 serves as the local node, and the Cisco 6705 as the remote node. It is also possible to create an INDL between two Cisco 6732 nodes.

Note The following procedures are also used to create a non-data link. A non-data link does not allow provisioning of a remote node, but it can still be used to carry inter-node traffic and cross connects.

Note An INDL created on an MSDSL-2W card must use the HDLU framing type. Before creating an INDL, provision the MSDSL-2W line for HDLU framing.

Each node must be provisioned with a separate "half link" before the INDL can be used. Complete the following procedures to establish communications with an INDL:

Create a Local Half Link

To create a half link from the local node to the remote node, complete the following steps starting in net view:

Step 1 Connect the EMS workstation to the local node (Cisco 6732).

Step 1 Go to the EMS net view. (See Figure 6-1.)

Figure 6-1: Net View

Step 2 Click and drag a line from the local node (Cisco 6732) to the remote node (Cisco 6705). (See Figure 6-2.)

Figure 6-2: Draw Line to Remote Node

Step 3 This creates a visual link between the two nodes. (See Figure 6-3.)

Figure 6-3: Visual Link

Step 4 From the menu bar, select File > Save to save the visual link.

Figure 6-4: Net View Menu

Step 5 Click on the Inter-Node Provision button (located in the upper right corner of the net view window). EMS launches the inter-node provisioning window. (See Figure 6-5.)

Figure 6-5: Inter Node Provisioning Window

Step 6 Double-click the line between the two nodes. EMS launches the inter-node link display. (See Figure 6-6.)

Figure 6-6: In ter-Node Link Display

Note

Step 7 Select a line from the local node display that will be provisioned with the half link.

Step 8 Click and drag a visual link from the line on the local node to the remote node. (See Figure 6-7.)

Figure 6-7: Draw Line to Remote Node

Step 9 After creating the visual link, EMS launches the inter node link provision window. (See Figure 6-8.)

Figure 6-8: Inter-Node Provision Window

Step 10 In the inter-node link provision window, set the following parameters:

Data Link: set to DS0 (uses a DS0 channel for the data link) or FDL (uses DS1 overhead bandwidth for the data link). Cisco recommends the DS0 format; some line cards (particularly the OC3-AUPSR card) can not use the FDL format.

Note

Data Link

None

Link Direction: set to LocalNode
Card Type: set to type of card used in the remote node
Card: set to the slot number of the card used in the remote node.
Line: set to the line number used in the remote node.

Step 11 Click Create (at the bottom of the window). EMS changes the Create button to Refresh. (See Figure 6-9.)

Figure 6-9: Local Half LInk Created

Step 12 Click Exit to close the inter node link provision window. EMS returns to the inter-node link display. (See Figure 6-10.)

Figure 6-10: Inter Node Link Display with Local Half Link

The newly created half link is shown as a blue line connecting the local node and remote node.

Step 13 Click Back to Network Map (at the top of the window) to return to the net view.

Create a Remote Half Link

After creating the INDL half link on the local node, a similar half link must created on the remote node---in this example, the Cisco 6705.

Step 1 Connect the EMS workstation to the remote node (Cisco 6705).

Step 2 Click on the Inter-Node Provision button (located in the upper right corner of the net view window). EMS launches the inter-node provisioning window. (See Figure 6-11.)

Figure 6-11: Inter-Node Provisioning Window

Step 3 Double-click the line between the two nodes. EMS launches the inter-node link display. (See Figure 6-12.)

Figure 6-12: Inter-Node Link Display

Note In the inter-node link display, the remote node (Cisco 6705) is at the left side of the display. The local node (Cisco 6732), shown as a gray box, is at the right side of the display.

Step 4 Select the line from the remote node display to be provisioned with the half link.

Note The line selected on the remote node must be the same line used in the "Create a Local Half Link" section.

Step 5 Click and drag a visual link from the local line to the remote node. (See Figure 6-13.)

Figure 6-13: Draw Line to Remote Node

Step 6 After creating the visual link, EMS launches the inter node link provision window. (See Figure 6-14.)

Figure 6-14: Inter Node Link Provision Window

Step 7 In the inter-node link provision window, set the following parameters:

Data Link: set to DS0 (uses DS0 line 1) or FDL (uses DS1 overhead bandwidth). Cisco recommends the DS0 format; some line cards (particularly the OC3-AUPSR card) can not use the FDL format.

Note The data link selection must be consistent with the selection in the

"Create a Local Half Link"

Note

Data Link

None

Link Direction: set to RemoteNode
Card Type: set to type of card used in the local node (in this example, the Cisco 6732)
Card: set to slot number of the card used in the local node.
Line: set to facility number of the line being used in the local node.

Step 8 Click Create (at the bottom of the window). EMS changes the Create button to Refresh. (See Figure 6-15.)

Step 9 Click Exit to close the inter node link provision window. EMS returns to the inter-node link display. (See Figure 6-16.)

Figure 6-16: Inter-Node Link Display with Local Half Link

The newly created half link is shown as a blue line connecting the remote node and local node.

Step 10 Click Back to Network Map (at the top of the window) to return to the net view. (See Figure 6-17.)

Figure 6-17: Net View with Visual Link

Note

Step 11 Open the remote node (Cisco 6705) by double-clicking the remote node icon in net view. EMS launches the node view of the remote node. (See Figure 6-18.)

Figure 6-18: Node View of Remote Node

Step 12 Double-click the node nameplate. (See Figure 6-19.)

Figure 6-19: Node View and Node Nameplate

Step 13 EMS launches the NE provision window. (See Figure 6-20.)

Figure 6-20: NE Provision Window

Step 14 From the function bar on the left, click on the Datalink Route Configuration button. This brings up the datalink route configuration window. (See Figure 6-21.)

Figure 6-21: Datalink Route Configuration Window

Step 15 Set the following parameters in the datalink route configuration window:

Card Type: Card used in the remote node (Cisco 6705)
Card: Slot number of the card used in the remote node
Line: Facility number of the line used on the card in the remote node
Destination Address: Leave blank
Gateway Address: IP address of the local node (Cisco 6732)
Netmask: Leave blank
Route Type: Set to Default

Click Add when finished.

Step 16 Click the Exit button (from the function bar) to return to the node view.

Step 17 Select File > Exit to return to the net view.

Step 18 Using the TCP/IP configuration utility on your EMS workstation, set the Default Gateway to the same address as the local node (Cisco 6732) IP address.

Figure 6-22 shows the TCP/IP configuration window for Windows NT. For the complete TCP/IP configuration procedure, see the "Configure TCP/IP on the EMS Workstation" section.

Figure 6-22: Windows NT---TCP/IP Properties

Step 19 Click OK to configure TCP/IP on the EMS workstation, and reboot if necessary.

To verify the INDL has been successfully created, connect a EMS workstation to the local node (Cisco 6732). Open EMS net view and double click on the remote node (the Cisco 6705). The remote node should open, displaying the node view. This means EMS is able to use the INDL to access the remote node.
