Configuring Extended DCN Functions

Configuring Extended DCN Functions

After configuring basic DCN functions, configure extended DCN functions as required.

Usage Scenario

In addition to basic data communication network (DCN) functions, an NE supports extended DCN functions.
  • If a gateway network element (GNE) belongs to multiple processes and areas, configure DCN with multiple processes and areas so that the GNE can manage all the NEs in different processes and areas.
  • When an NE functions as a GNE and manages RTN NEs, configure the GNE to work in compatible mode.
  • When a large number of NEs are attached to a GNE that resides on more than one ring network, ring network services may affect each other. To address this problem, configure DCN packet transparent transmission.

Pre-configuration Tasks

Before configuring extended DCN functions, globally enable DCN.

Configuration Procedures

Perform one or more of the following configurations as required.

Configuring Multi-Process and Multi-Area DCN

If a GNE belongs to multiple processes and areas, multi-process and multi-area DCN can be configured so that the GNE can manage all the NEs in different processes and areas.

Background Information

On large-scale DCNs, different NEs are usually deployed in multiple processes and areas. In this situation, allocate interfaces on the GNE to different processes and areas and enable the GNE to advertise its NEIP address to these processes and areas so that the GNE can learn information about the DCN core routing tables of all the NEs in these processes and areas and manage the NEs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run dcn ospf enable [ process-id ] area area-id

    A process and an area are specified for DCN serial interfaces or sub-interfaces 4094.

    NOTE:
    In most cases, the network (OSPF) command adds an interface to the specified process and area. However, this command does not apply to DCN serial interfaces or sub-interfaces 4094 because they borrow the same IP address.

  4. Run quit

    The system view is displayed.

  5. Run dcn

    The DCN view is displayed.

  6. Run advertise neip

    The GNE is enabled to advertise its NEIP address to multiple processes and areas.

  7. Run commit

    The configuration is committed.

Configuring the DCN Compatible Mode on a GNE

The DCN compatible mode can be configured on a GNE so that it can manage RTNs.

Background Information

RTNs use microwave links for service transmission, and no cables are required, which reduces network deployment cost.

A GNE can manage RTNs only when the DCN compatible mode is configured on the GNE for DCN communication with the RTNs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run dcn

    The DCN view is displayed.

  3. Run set compatible mode

    The DCN compatible mode is configured on the GNE.

  4. Run commit

    The configuration is committed.

Disabling Automatic Recovery of Default DCN Interfaces

The DCN plug-and-play function is implemented through automatic creation and recovery of default DCN interfaces. If a default E1 channel of a CPOS or E1 subcard does not require DCN plug-and-play, disable automatic recovery of the corresponding default DCN interface so that the interface can be reserved for other purposes.

Context

After DCN is enabled on a CPOS or E1 subcard, default DCN E1 channels are created automatically, DCN is enabled on the serial interfaces formed by E1 channels' timeslots, and DCN tunnels are established. If DCN tunnels are not required on a CPOS or E1 subcard, disable automatic recovery of corresponding default DCN interfaces.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run dcn

    The DCN function is enabled globally, and the DCN view is displayed.

  3. Run auto-restore e1-channel-set disable

    Automatic recovery is disabled for the default DCN interfaces formed by E1 channels' timeslots on a CPOS or E1 subcard.

    After automatic recovery is disabled:

    • If you delete the default DCN E1 channels that were created automatically, save the configuration, and restart the device, automatic recovery is disabled.
    • If you install a new CPOS or E1 subcard, the default DCN E1 channels will not be created automatically.

  4. Run commit

    The configuration is committed.

Enabling DCN Communication Through Sub-interface 4094

This section describes how to configure a sub-interface numbered 4094 for each Huawei and non-Huawei NE to implement DCN communication.

Usage Scenario

DCN communication uses the Huawei proprietary protocol. Therefore, Huawei NEs cannot communicate with non-Huawei NEs. To implement DCN communication between Huawei NEs and non-Huawei NEs, configure sub-interfaces numbered 4094.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run dcn mode vlan

    A sub-interface numbered 4094 is configured.

  4. Run commit

    The configuration is committed.

Configuring an Authentication Message for the Private TLV That Supports NMS Automatic NE Management in LLDP Packets

This section describes how to configure an authentication message for the private TLV that supports NMS automatic NE management in LLDP packets.

Usage Scenario

When NEs use sub-interfaces numbered 4094 for DCN communication, an NE on which NMS automatic NE management is configured encapsulates an authentication message in the private TLV that supports NMS automatic NE management in an LLDP packet before sending the LLDP packet to a downstream NE. Upon receipt of the LLDP packet, the downstream NE parses the private TLV if the downstream NE supports NMS automatic NE management. If the authentication message carried in the LLDP packet is the same as the one configured locally, NMS automatic NE management takes effect on the downstream NE. If the authentication message carried in the LLDP packet is different from the one configured locally, NMS automatic NE management does not take effect on the downstream NE.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run lldp enable-dcn authentication authentication-string

    An authentication message is configured for the private TLV that supports NMS automatic NE management in LLDP packets.

  3. Run commit

    The configuration is committed.

Verifying the Configuration of Extended DCN Functions

After configuring extended DCN functions, verify the configuration.

Prerequisites

Extended DCN functions have been configured on all NEs.

Procedure

  • Run the display dcn brief command to check configurations of the GNE.
  • Run the display dcn ne-info command to check information about the DCN core routing table.
  • Run the display dcn interface [ interface-type interface-number ] command to check DCN configurations and traffic statistics of an interface.
  • Run the display dcn mode vlan interface command to view information about sub-interfaces 4094.
  • Run the display dcn element-info command to view details about all NEs that use sub-interfaces 4094 for DCN communication.
