Method used to obtain DNS and NetBIOS information through the public network

25

Huawei AR series routers can automatically assign the DNS server IP address allocated by a carrier, DNS domain name suffix, and NetBIOS server address to a DHCP client. The configuration procedure is as follows.
-Interface address pool
[Huawei] interface gigabitethernet 1/0/0
[Huawei-GigabitEthernet1/0/0] dhcp select interface
[Huawei-GigabitEthernet1/0/0] dhcp server import all //Enable the interface to automatically obtain the DNS and NetBIOS server addresses.
-Global address pool
[Huawei] ip pool global
[Huawei-ip-pool-global] import all //Enable the AR to automatically obtain the DNS and NetBIOS server addresses in the global address pool.

The DHCP client cannot obtain DNS information on the AR
DPossible causes are as follows: 1. The route from the AR to the DHCP server is unreachable. 2. The DNS and DHCP configuration modes are different. When the DHCP server assigns an IP address and gateway address to a client, the DHCP server also sends the DNS server address to the client. Ensure that the DNS server address and DHCP server address are configured in the global address pool or on an interface so that the DHCP server can find the DNS server IP address and deliver it.

How are DNS and NetBIOS server addresses configured on an AR
The AR can automatically assign the DNS server IP address allocated by a carrier, DNS domain name suffix, and NetBIOS server address to a DHCP client. Perform the following configurations: - Interface-based [Huawei] interface gigabitethernet 1/0/0 [Huawei-GigabitEthernet1/0/0] dhcp select interface [Huawei-GigabitEthernet1/0/0] dhcp server import all //Enable the interface to automatically obtain the DNS and NetBIOS server addresses. - Global mode [Huawei] ip pool global [Huawei-ip-pool-global] import all //Enable the AR to automatically obtain the DNS and NetBIOS server addresses in the global address pool.

Netbios parameter settings on S series switch
When S series switches (except S1700 switches) function as DHCP servers, they can deliver NetBIOS service parameters to clients through DHCP. The configuration process is as follows: - Interface address pool: [HUAWEI] interface vlanif 10 [HUAWEI-Vlanif10] ip address 10.10.10.1 24 [HUAWEI-Vlanif10] dhcp select interface [HUAWEI-Vlanif10] dhcp server nbns-list 10.10.1.1 //Configure the NetBIOS server address. [HUAWEI-Vlanif10] dhcp server netbios-type p-node //Configure the NetBIOS node type. - Global address pool: [HUAWEI] ip pool pool1 [HUAWEI-ip-pool-pool1] nbns-list 10.10.1.1 //Configure the NetBIOS server address. [HUAWEI-ip-pool-pool1] netbios-type p-node //Configure the NetBIOS node type. - Using a DHCP Option template: [HUAWEI] dhcp option template template1 [HUAWEI-dhcp-option-template-template1] nbns-list 10.10.1.1 //Configure the NetBIOS server address. [HUAWEI-dhcp-option-template-template1] netbios-type p-node //Configure the NetBIOS node type.

Method used to collect TC information
You need to log in to TCM to collect the TC information. For details, see section 19 "Log Collection" in the TCM V100R001C00SPC200 Product Documents 01. (2) The specific path is as follows: http://support.huawei.com/enterprise/en/doc/DOC1000038441?idPath=7919749|9856522|21782478|21782484|8677678
