Soyou need to perform WINS-related configuration for most Windows-based hosts.To implement host name-to-IP address translation for DHCP clients, you should enable the DHCPserver to assign WINS server addresses when assigning IP addresses to DHCP clients. Currently, youcan configure up to eight WINS addresses for a DHCP address pool.Host name-to-IP address mappings are needed for DHCP clients communicating through NetBIOSprotocol. According to the way to establish the mapping, NetBIOS nodes fall into the following fourcategories:z B-node. Nodes of this type establish their mappings through broadcasting (The character b standsfor the word broadcast). The source node obtains the IP address of the destination node bysending the broadcast packet containing the host name of the destination node. After receiving thebroadcast packet, the destination node returns its IP address to the source node.z P-node. Nodes of this type establish their mappings by sending unicast packets to WINS servers.(The character p stands for peer-to-peer). The source node sends the unicast packet to the WINSserver. After receiving the unicast packet, the WINS server returns the IP address correspondingto the destination node name to the source node.z M-node. Nodes of this type are p-nodes mixed with broadcasting features (The character m standsfor the word mixed), that is to say, this type of nodes obtain mappings by sending broadcastpackets first. If they fail to obtain mappings, they send unicast packets to the WINS server to obtainmappings.z H-node. Nodes of this type are b-nodes mixed with peer-to-peer features. (The character h standsfor the word hybrid), that is to say, this type of nodes obtain mappings by sending unicast packetsto WINS servers first. If they fail to obtain mappings, they send broadcast packets to obtainmappings.Follow these steps to configure WINS servers for the DHCP client:To do… Use the command… RemarksEnter system view system-view —Enter DHCP address pool view dhcp server ip-poolpool-name —Configure WINS serveraddresses for DHCP clients nbns-list ip-address&<1-8>RequiredBy default, no WINS serveraddress is configured.
