(Optional) Configuring the DNS Service and NetBIOS Service on the DHCP Client

(Optional) Configuring the DNS Service and NetBIOS Service on the DHCP Client


To ensure normal operations of DHCP clients, you can specify the DNS server address and the NetBIOS server address when the DHCP server assigns an IP address to the DHCP client.NetBIOS:Network Basic Input Output System. When a DHCP client uses the NetBIOS protocol for communication, host names must be mapped to IP addresses. Based on the modes of obtaining mapping, NetBIOS nodes are classified into the following types:
  • b-node: indicates a node in broadcast mode. This node obtains mappings in broadcast mode.

  • p-node: indicates a node in peer-to-peer mode. This node obtains mappings by communicating with the NetBIOS server.

  • m-node: indicates a node in mixed mode. An m-node is a p-node that has some broadcast features.

  • h-node: indicates a node in hybrid mode. An h-node is a b-type node enabled with the end-to-end communication mechanism.


  1. Run system-view

    The system view is displayed.

  2. Run ip pool ip-pool-name

    The IP address pool view is displayed.

  3. Run domain-name domain-name

    The DNS domain name to be assigned to a DHCP client is configured.

  4. Run dns-list ip-address &<1-8>

    The IP address of the DNS server is configured for a DHCP client.

    To load balance the traffic and improve network reliability, configure multiple DNS servers. Each address pool can be configured with a maximum of eight DNS server addresses.

  5. Run nbns-list ip-address &<1-8>

    The IP address of the NetBIOS server used by the DHCP client is assigned.

    Each address pool can be configured with a maximum of eight NetBIOS server address.

  6. Run netbios-type { b-node | h-node | m-node | p-node }

    The NetBIOS node type of the DHCP client is configured.

    By default, no NetBIOS node type is specified for DHCP clients.

  7. Run commit

    The configuration is committed.
