Procedure 9-4: Provision manual ring map

Overview

Use this procedure to perform the following at a node in a 2-fiber bidirectional line switched ring (BLSR):

Establish a new manual ring map
Add a node(s) to an existing manual ring map
Delete a node(s) from an existing manual ring map.

Important!

If deleting a node(s) from an existing ring map, then the circuits that add/drop to the deleted node(s) must be deleted. Refer to Chapter 10, TDM service provisioning procedures and Chapter 11, Ethernet/Data network provisioning procedures.

Privilege level

You must log in as a Privileged or General user to complete this procedure.

Before you begin

Prior to performing this procedure:

Verify that the work instructions specify the 2F BLSR protection group (port Application parameter must be provisioned 2F BLSR), Ring ID, and node ID(s).

Steps

Complete the following steps to provision the manual ring map at a node(s) in a 2-fiber bidirectional line switched ring (BLSR).

If the network element is equipped with...	Then...
Release 3.0 or later software,	verify that Automatic Ring Discovery is disabled by selecting View → Protection. Click on the required 2F BLSR protection groupand Select. Then click on the Provisionable Parameters tab and observe the Automatic Ring Discovery parameter. Continue with Step 2.

If...	Then...
Establishing a new manual ring map,	Continue with Step 5.
Adding a node(s) to an existing manual ring map,	Proceed to Step 10.
Deleting a node(s) from an existing manual ring map,	Proceed to Step 13.

Click on the required Ring ID and Select.

Result:

A dialog box appears stating that there is no existing manual ring map, you will be configuring a new manual ring map. Click OK. The Configure Manual Ring window opens showing the local node and an unnamed node. (Refer to following figure.)

Important!

The local node appears on the right side of the Configure Manual Ring screen. This shows the NE Name (DMX) and Node ID (0). The Node ID of the local node may need to be changed to comply with the work instructions.

If required, right click on the local node and change the Node ID according to the work instructions. Click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes, and the modified node information appears on the Configure Manual Ring screen.

Important!

The NE Name and Node ID of the unnamed node must be modified to the NE Name and node ID of the node that is connected to the East port (for example, Main-2) of the Local node per the work instructions.

Right click on the unnamed node (UNNAMED 1) and change the NE Name and Node ID according to the work instructions. Click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes, and the modified node information appears on the Configure Manual Ring screen.

Important!

In the manual ring map, nodes are added in the clockwise (East) direction only from the node that is selected.

To add another node, click on the required node and click Add Node. Enter the NE Name and Node ID of the next node in the East direction (clockwise) according to the work instructions. Click OK.

Result:

A dialog box appears asking you to confirm adding a new node to the manual ring map. Click Yes, and the new node appears on the Configure Manual Ring screen.

Are additional nodes to be added?

If...

Then...

Yes,

Important!

A maximum of 16 nodes can be added to the manual ring map.

As required per the work instructions, repeat Step 8 to add additional nodes to the manual ring map. Then proceed to Step 16.

No,

Proceed to Step 16.

Click on the required Ring ID and Select.

Result:

The Configure Manual Ring window opens.

Important!

The local node appears at the top of the Configure Manual Ring screen. In the manual ring map, nodes are added in the clockwise (East) direction only from the node that is selected.

Select the required node and then click Add Node. Enter the NE Name and Node ID of the new node according to the work instructions. Click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes, and the new node appears on the Configure Manual Ring screen.

Are additional nodes to be added?

If...

Then...

Yes,

Important!

A maximum of 16 nodes can be added to the manual ring map.

As required per the work instructions, repeat Step 11 to add additional nodes to the manual ring map. Then proceed to Step 16.

No,

Proceed to Step 16.

Click on the required Ring ID and Select.

Result:

The Configure Manual Ring window opens.

Important!

The local node appears at the top of the Configure Manual Ring screen.

Click on the node to be deleted and then click Remove Node.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes and the node is removed from the Configure Manual Ring screen.

Are additional nodes to be deleted?

If...	Then...
Yes,	As required per the work instructions, repeat Step 14 to delete additional nodes from the manual ring map. Then proceed to Step 16.
No,	Proceed to Step 16.

Click Apply.

Select Configuration → Activate Manual Ring Map.

Result:
