13.3.1

Creating MSSPRing

Before creating a new MSSPRING, the user must know the ring topology and link information about the NE.

Follow the steps below to create a new ring with MSSRPing Protection:

1. In the < MSSPRing Management> window, click <Create>. The <Create Ring> window will appear. (See Fig. 13.11)

Fig. 13.11 Set Ring Property

Input a number as <Ring Id> and arbitrary string as <Ring Label>. Click <Next> to set the NEs in the ring.

Note: The maximum number of the ring is 16, and the Ring ID should be a number between 1 and 5000. If the information is incorrect or some items are not inputted, a warning window will

ii

Fig. 13.12 Warning Window

A new window will appear. A number of NEs will appear on the window, the total number of which equals the number that the user input in the previous window. (See Fig. 13.13)

Fig. 13.13 Create Ring

Click the icon of each NE, and input the corresponding IP address in the pop-up dialog. The IP address will appear below the icon of the NE. Click each of the links to set up the Link Port properties in the pop-up dialog. (See Fig. 13.14) Select board and port from the drop-down menu of the <Link Port> panel, input <Slot number> and <Port Number> in the <Peer Link Port> panel, and click OK to confirm. The color of the corresponding link will turn green.

When all the NEs and links are configured, click <OK> in the <Create Ring> window, and a confirmation dialog will pop up. Click <Yes> to confirm to add protection to the ring. (See Fig. 13.15)

Fig. 13.15 Confirm to add protection

Then the MSSPRING is created, and it will be listed in <MSSPRing Management> window. (See Fig. 13.16)

Modifying MSSPRing

Select one MSSPRing in the <Ring List> table, and then click <Property> to view and modify its properties. (See Fig. 13.17)

Fig. 13.17 MSSPRing Property

In the <Protection Details> tab, click <Delete Protection> and select <Yes> in the pop-up dialog to delete protection from the MSSPRing. All the other buttons and tabs will be grayed out, and this button will become <Add Protection>. Click the <Add Protection> button to re-add protection onto the MSSPRing.

Click <Enable Ring> and select <Yes> in the pop-up dialog to change the MSSPRing Enable status to “Enable”. Then the button will become <Disable Ring>. Click the <Disable Ring> button to change the MSSPRing Enable status to “Disable”.

Click <Suspend Ring> and select <Yes> in the pop-up dialog to suspend the MSSPRing. Then the button will become <Unsuspend Ring>. Click the <Unsuspend Ring> button to un-suspend the MSSPRing.

Click <Refresh> to get latest information.

Click <Modify> to change configuration of this MSSPRing. The steps are similar to creating a MSSPRing.

When an MSSPRing is enabled, the <Command> and <Advanced> buttons are available. Click <Command> to enter <Command of MS SPRing> window. (See Fig. 13.18)

Fig. 13.18 Command of MS SPRing

In this window, the last switch information can be retrieved. Click <Refresh> to get latest information.

Select <New Command> in the drop-down menu and click <Apply> to perform new command.

The available commands have:

<manual switching ring>: This command performs the ring switch for the normal traffic from the working channels to the protection channels for the span between the node at which the command is initiated and the adjacent node to which the command is destined. This switch occurs if the protection channels are not in an SD condition and are not satisfying an equal or higher priority bridge request (including failure of the protection channels).

<forced switching ring>: This command performs the ring switch for normal traffic from the working channels to the protection channels for the span between the node at which the command is initiated and the adjacent node to which the command is destined. This switch occurs regardless of the state of the protection channels, unless the protection channels are satisfying a higher priority bridge request.

<lockout protection>: This command prevents the ring wraps anywhere for any protection activity and prevents using ring switches anywhere in the ring. If any ring switches exist in the ring, this command causes the switches to drop. If there is a span switch for this span, it is dropped. Thus, all ring switching is prevented (and pre-empted), and span switching is prevented only on the locked-out span.

<clear>: This command clears the externally initiated command and WTR at the node to which the command was addressed. The NE-to-NE signaling following removal of the externally initiated commands is performed using the NR code.

The latest launched command is listed in <Last Command> field. The execution result of the latest command is shown in the <Status of last command> field.

There are two types of command execution results: <Command Successful> — launched command succeed
