(Optional) Configuring NetBIOS Configurations Allocated by a DHCP Server

Context

If DHCP clients on your network use NetBIOS and you want them to receive NetBIOS configurations through DHCP, configure the DHCP server to provide NetBIOS configurations.

Procedure

Based on an interface address pool
1. Enter the system view.
```
system-view
```
2. Enter the interface or sub-interface view.
```
interface interface-type interface-number[.subinterface-number ]
```
  Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5731-S, S5731S-S, S6720-HI, S5732-H, S6730-H, S6730S-H, S6730-S, S6730S-S, S6720-EI, and S6720S-EI support sub-interfaces.
3. (Optional) On an Ethernet interface, run undo portswitch
  The interface is switched to Layer 3 mode.
  
  By default, an Ethernet interface works in Layer 2 mode.
  
  Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
4. Configure the NetBIOS server IP address and NetBIOS node type to be allocated to DHCP clients.
  - Configure the NetBIOS server IP address to be allocated to DHCP clients.
```
dhcp server nbns-list ip-address &<1-8>
```
    By default, no NetBIOS server IP address is configured in an address pool.
    
    Each address pool can be configured with a maximum of eight NetBIOS server IP addresses.
  - Configure a NetBIOS node type to be allocated to DHCP clients.
```
dhcp server netbios-type { b-node | h-node | m-node | p-node }
```
    By default, no NetBIOS node type is configured for DHCP clients.
Based on a global address pool in the global address pool view
1. Enter the system view.
```
system-view 
```
2. Enter the global address pool view.
```
ip pool ip-pool-name
```
3. Configure the NetBIOS server IP address and NetBIOS node type to be allocated to DHCP clients.
  - Configure the NetBIOS server IP address to be allocated to DHCP clients.
```
nbns-list ip-address &<1-8>
```
    By default, no NetBIOS server IP address is configured in an address pool.
    
    Each address pool can be configured with a maximum of eight NetBIOS server IP addresses.
  - Configure a NetBIOS node type to be allocated to DHCP clients.
```
netbios-type { b-node | h-node | m-node | p-node }
```
    By default, no NetBIOS node type is configured.
In the DHCP Option template view
1. Enter the system view.
```
system-view
```
2. Create a DHCP Option template and enter the DHCP Option template view.
```
dhcp option template template-name
```
  By default, no DHCP Option template is created.
  
  To allocate network parameters except IP addresses to static clients, configure a DHCP Option template. Network parameters configured in the DHCP Option template view take effect only for static clients. For static clients, if a network parameter is configured in both the DHCP Option template view and global address pool view, only the configuration in the DHCP Option template view takes effect.
  
  To allocate only IP addresses to static clients (for details, see (Optional) Configuring Fixed IP Addresses in an Address Pool), you do not need to configure a DHCP Option template.
3. Configure the NetBIOS server IP address and NetBIOS node type to be allocated to DHCP clients.
  - Configure the NetBIOS server IP address to be allocated to DHCP clients.
```
nbns-list ip-address &<1-8>
```
    By default, no NetBIOS server IP address is configured.
    
    Each address pool can be configured with a maximum of eight NetBIOS server IP addresses.
  - Configure a NetBIOS node type to be allocated to DHCP clients.
```
netbios-type { b-node | h-node | m-node | p-node }
```
    By default, no NetBIOS node type is configured.
  If you need to configure other items in the DHCP Option template view, complete them first before performing the following steps.
4. (Optional) Return to the system view.
```
quit
```
5. (Optional) Enter the global address pool view.
```
ip pool ip-pool-name
```
6. (Optional) Bind a DHCP Option template to static clients.
```
static-bind ip-address ip-address mac-address mac-address option-template template-name
```
