La Posesión Pacífica en la Jurisprudencia

The ECC protocol uses an NE ID to uniquely identify an NE. When planning the network, you must assign a unique ID for each NE. If an NE ID conflicts with another one, ECC routing collision is caused. In this case, certain NEs cannot be managed.

Prerequisite

Tools, Meters, and Materials

Web LCT or T2000

Precautions

CAUTION

NE ID conflict leads to unreachable of NEs. Therefore, the ID of an NE must be unique on the network.

CAUTION

If an NE is configured with the inter-subrack wavelength protection, you need to delete the protection before changing the NE ID and configure the protection again after changing the NE ID.

NOTE

If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies with the NE ID. Once the IP address of the NE is changed, the association between the NE ID and IP address is deleted automatically.

TIP

If an NE is unreachable after the NE ID is changed, you can change the name of the NE only after searching for and logging in to the NE again. Therefore, you are recommended to change the NE name before changing the NE ID.

Procedure

l Operations on the Web LCT

1. In the Function Tree in the NE Explorer, choose Report > Board Detail Information Report. The Query dialog box is displayed to show the query progress. When the query is complete, an operation result dialog box is displayed. Click Close.

2. Obtain the bar code of the chassis from the queried information about the SCC board. The following figure shows the bar code of the chassis.

3. Find the bar code of the chassis in the station bar code return table to determine the position and name of the station where the login NE is located. Then determine the ID and name of the NE according to the NE ID and name planning provided by the customer.

4. In the Function Tree, choose Configuration > NE Attribute. Enter Name of the NE according to the customer planning, and then click Apply.

NOTE

You can enter an NE name with a maximum of 64 characters consisting of letters, symbols, and numbers, excluding special characters that are not allowed on the interface, such as |, :, *, ?, ", <, and >.

5. Click Modify NE ID. In the Modify NE ID dialog box that is displayed, enter values in the New ID and New Extended ID fields, and then click OK. A warning dialog box is displayed, click Yes. A dialog box indicating that the operation is successful is displayed, click Close to complete changing the NE ID. At this time, the NE is unreachable.

6. Navigate to NE List and delete the unreachable NE. Search for and create NEs again.

TIP

When you search for the NEs again, the NE IDs displayed on the interface are the NE IDs after change. The NE names, however, change to the new NE names automatically only after you create and log in to the NEs again.

NOTE

l Operations on the T2000

1. In the Main Menu, choose Report > Board Manufacture Information Report. Select the SCC board that you want to query in the Function Tree, and then click

.

2. Obtain the bar code of the chassis on the Board Manufacture Information Report tab.

3. Find the bar code of the chassis in the station bar code return table to determine the position and name of the station where the queried NE is located. Then determine the ID and name of the NE according to the NE ID and name planning provided by the customer.

4. In the NE Explorer, click and select an NE.

5. In the Function Tree, choose Configuration > NE Attribute. Enter Name of the NE according to the customer's planning, and then click Apply. A dialog box indicating that the operation is successful is displayed. Click Close.

NOTE

You can enter an NE name with a maximum of 64 characters consisting of letters, symbols, and numbers, excluding special characters that are not allowed on the interface, such as |, :, *, ?, ", <, and >.

6. Click Modify NE ID. In the Modify NE ID dialog box that is displayed, enter values in the New ID and New Extended ID fields, and then click OK. A warning dialog box is displayed, click Yes. A dialog box indicating that the operation is successful is displayed, click Close to complete changing the NE ID.

Deleting NEs You may need to delete an NE after the ID or IP address of the NE is changed. In this case, see this section to delete the NE.

Creating an NE User The user names for logging in to an NE must be different. You can create an NE user as required.

Switching a Login NE User

You can switch a login NE user without logging out of the T2000 or Web LCT.
