Configuring Basic DCN Functions

Configuring Basic DCN Functions

This chapter describes how to enable DCN globally, enable DCN on an interface, enable the automatic NE report function on a GNE, and configure NE IDs and NE IP addresses.

Usage Scenario

The construction of a large network requires significant human and material resources if software commissioning engineers have to configure devices on site, causing high operational expenditure (OPEX). DCN can reduce the OPEX by allowing GNEs to manage NEs. DCN enables NMSs to rapidly detect new NEs and remotely control and manage the NEs.

The DCN technique offers a mechanism to implement plug-and-play. After each NE is initialized, it generates an NE IP address based on its NE ID, creates a mapping entry for the NE ID and NE IP address, adds the mapping entry to its DCN core routing table, and uses OSPF to advertise the mapping entry to all other NEs on the DCN. Therefore, all the NEs on the DCN can communicate with each other.

The DCN feature allows NMSs to use GNEs to manage NEs. A GNE supports the automatic NE report function, enabling the GNE to automatically report a new NE's information to NMSs immediately after the GNE detects the new NE. Then the NMSs can manage the new NE in time. In addition, a GNE can send a trap to its interworking NMSs when the number of NEs connected to the GNE reaches the alarm threshold. Then the NMSs will generate alarms to inform users of this information.

Pre-configuration Tasks

Before configuring basic DCN functions, complete the following tasks:

  • Configure reachable routes between the GNE and NMSs.
  • Configure reachable routes between the GNE and NEs.
    NOTE:

    When the GNE is connected to an NE for the first time, the SSH default user account is used for login.

Procedure

  1. Enable DCN Globally.
    1. Run system-view

      The system view is displayed.

    2. Run dcn

      The DCN feature is enabled globally.

    3. Run commit

      The configuration is committed.

  2. Enable DCN on an interface and specify a DCN VLAN.

    In router mode:

    1. Run the system-view command to enter the system view.
    2. Run the interface interface-type interface-number command to enter the interface view.
    3. Run the dcn command to enable DCN on the interface.
    4. Run the dcn vlan vlan-id or dcn vlan { beginvlan-id [ to endvlan-id ] } &<1–64>command to specify a DCN VLAN.
    5. Run the commit command to commit the configuration.

    NOTE:

    In router mode, a DCN VLAN can be a service VLAN.

    1. Run the system-view command to enter the system view.
    2. Run the interface interface-type interface-number command to enter the interface view.

    4. Run the dcn vlan vlan-id command to specify a DCN VLAN.
    5. Run the commit command to commit the configuration.

    NOTE:

    In transport mode, ony one DCN VLAN can be configured. And it is conflicted with service VLAN.

  3. Configure the automatic NE report function on a GNE.
    1. Run system-view

      The system view is displayed.

    2. Run dcn

      The DCN view is displayed.

    3. Run auto-report

      The automatic NE report function is enabled.

    4. Run commit

  • Run the display dcn ne-info command to check information about the DCN core routing table.
  • Run the display dcn global command to check whether DCN is enabled globally.
  • Run the display dcn default-port command to check the interface on which DCN is enabled by default.
  • Run the display dcn interface [ interface-type interface-number ] command to check DCN configurations and traffic statistics of an interface.
  • Run the display dcn warning command to check DCN trap information.

Follow-up Procedure

An NMS's IP address is a public IP address, and a GNE's NE IP address is a Layer 3 VPN address. To implement address conversion, specify the interface that connects a GNE to an NMS, bind the interface to a DCN VPN instance, and set an IP address for the interface. After DCN is enabled globally on the GNE, it automatically generates a DCN VPN instance named __dcn_vpn__. Detailed operations are as follows:
  • Run interface interface-type interface-number

    The interface view is displayed.

  • Run ip binding vpn-instance vpn-instance-name

    A DCN VPN instance is bound to the interface.

  • Run ip address { mask | mask-length }

    An IP address is set for the interface.
