Creating NEs

Creating NEs

Each piece of equipment is represented as an NE on the U2000. Before the U2000 manages the actual equipment, you need to create the corresponding NEs on the U2000. There are two NE creation methods, namely, creating a single NE and creating NEs in batches. When you need to create a large number of NEs, for example, during the deployment, it is recommended that you use the method of creating NEs in batches. When you need to create only a few NEs, it is recommended that you use the method of creating a single NE.

Searching for and Creating NEs

After connecting the NMS computer to the equipment, a software commissioning engineer needs to search for the NE in the data center before commissioning the equipment.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • The U2000 must communicate with the gateway NE normally.
  • The NE Explorer instance of the NEs must be created.

Procedure

  1. Choose File > Discovery > NE from the Main Menu. Then, the NE Discovery window is displayed.
  2. Choose Transport NE Search tab, Click Add. Then, the Input Search Domain dialog box is displayed.
  3. Set Address Type to IP Address Range of GNE, IP Address of GNE, or NSAP Address. Enter Search Address. Then, Click OK.

    NOTE:
    You can repeat Steps 2 and 3 to add more search domains. You can also delete the system default search domain.
    • If you search for the NEs according to the IP address of the gateway NE and if the IP address of the U2000 computer and the IP address of the gateway NE are within the same network segment, you can set Address Type to IP Address Range of GNE or IP Address of GNE. The default value of Search Address is 129.9.255.255.
    • If the IP addresses of the gateway NE and the U2000 computer are in two different network segments, you can set Address Type to IP Address of GNE only.
    • If you search the NEs according to the NSAP addresses of the NEs, you can set Address Type to NSAP address only.

  4. In the NE Discovery window, ClickNext.
  5. After the search is complete, select the uncreated NEs from the Result list and then click Create. The Create dialog box is displayed.
  6. Enter the NE user name and password.

    NOTE:
    • The default NE user is root.
    • The default password is Changeme_123.

    To ensure system security, change the password promptly, update it periodically, and save it properly.

  7. Click OK.

Follow-up Procedure

If you fail to log in to the created NE, the possible causes are listed as follows:

  • The password for the NE user is incorrect. In this case, enter the correct password for the NE user.
  • The NE user is invalid. Change to use a valid NE user.

Creating NEs Manually

After an NE is created, you can use the U2000 to manage the NE. Creating a single NE is not as quick and accurate as creating NEs in batches. But you can create a single NE regardless of whether the data is configured on the NE side.

Prerequisites

  • You are an NM user with Maintenance Group rights or higher.
  • The NE Explorer instance of the NEs must be created.
Background Information

First create a gateway NE, and then create a non-gateway NE.

Procedure

  1. Right-click in the blank area of the Main Topology and choose New > NE from the shortcut menu. Then, the Create NE dialog box is displayed.
  2. Select the NE type from the Object Type drop-down list.
  3. Set ID, Extended ID, Name, and Remarks

    NOTE:

    The IP address of an NE does not need to be manually set and varies with NE IDs. The format of an IP address is 129.E.A.B. The second number E is the extended ID of the NE, which does not vary with the NE IDs. The default value is 9. The third number A and fourth number B are the highest eight bits and lowest eight bits of an NE ID. When the IP address of an NE is manually set, the mapping relationship between the IP address and NE ID does not exist.



  4. To create a gateway NE, proceed to Step 5. To create a non-gateway NE, go to Step 6.
  5. Choose Gateway Type and Protocol, and set the IP address.
    1. Select Gateway from the Gateway Type drop-down list.
    2. Select the Protocol type.

      If...

      Then...

      The U2000 communicates with NEs through the IP protocol

      Select IP from the Protocol drop-down list. Set IP Address of the gateway NE and use the default value of the Port number.

      The U2000 communicates with NEs through the OSI protocol

      Select OSI from the Protocol drop-down list. Set NSAP Address of the gateway NE.

  6. Select Non-Gateway from the Gateway Type drop-down list. Select the gateway NE to which the NE belongs from the Affiliated Gateway drop-down list.
  7. Set NE User and Password.

    NOTE:

    The default NE user is root, and the default password is Changeme_123.

    To ensure system security, change the password promptly, update it periodically, and save it properly.

  8. Optional: If you need not deliver the NE configuration data from the U2000 to the NE, select the NE Preconfiguration check box and set NE Software Version.

    NOTE:
    Do not deliver the NE preconfiguration data from the U2000 to the NE if the freconfiguration data is inconsistent with the actual configurations on the NE. Otherwise, the services on the NE are affected.

  9. Click OK. Click in the blank area of the Main Topology. Then, the NE icon is displayed at the position where you clicked.

    NOTE:
    If the NE creation is incorrect or if the communication between the NE and the U2000 is abnormal, the NE is displayed in grey.

Result

After an NE is successfully created, the system automatically saves the information, such as the IP address, NSAP address, subnet mask, and NE ID to the U2000 database.

Follow-up Procedure

if you fail to log in to the created NE, the possible causes are listed as follows:

  • The communication between the U2000 and the NE is abnormal. In this case, check the settings of communication parameters, such as the IP address and ID of the NE.
  • The NE user is invalid. Change to use a valid NE user.
