Configuring NetBIOS Node Type

Configuring NetBIOS ( NBNS) node type is a pool-specific option and will be offered to the clients in the pool as a configuration parameter.

To configure NetBIOS node type:

Create a pool and enter the DHCP Pool Configuration mode
iS5comm(config)# ip dhcp pool <pool number (1-2147483647)>

iS5comm(config)# ip dhcp pool 1

A pool number is entered. The range is from 1 to 2147483647.
Configure the NetBIOS node type.

The NetBIOS node type option allows NetBIOS over TCP/ IP clients which are configurable to be configured as described in RFC 1001/1002. The node types are B-node, P-node (peer-to-pier), M-node (mixed or BroadcastNBNS), and H-node(hybrid or NBNSBroadcast). See RFC 2132 sec 8.7 for more details.

iS5comm(dhcp-config)# netbios-node-type <node type>

iS5comm(dhcp-config)# netbios-node-type b-node

The NetBIOS node type is configured as B-node. B-node stands for Broadcast only method and uses NetBIOS name queries for name registration and name resolution. The code for this option is 46 as per RF 2132.
Verify the NetBIOS node type.
iS5comm(dhcp-config)# end

iS5comm# show ip dhcp server pools
