Configuring DHCP Server 693
■ p-node: Nodes of this type establish their mappings by communicating with
NetBIOS server. (p stands for peer-to-peer.)
■ m-node: Nodes of this type are p nodes which take some broadcast features.
(m stands for mixed.)
■ h-node: Nodes of this type are b nodes which take peer-to-peer mechanism. (h
stands for hybrid.)
Configuring NetBIOS node type for a global DHCP address pool
Perform the following configuration in DHCP address pool view.
Configuring NetBIOS node type for current VLAN interface
Perform the following configuration in VLAN interface view.
Configuring NetBIOS node type for multiple VLAN interfaces
Perform the following configuration in system view.
By default, the DHCP clients of global and VLAN interface address pools are all of
h-node type.
Configuring Custom
DHCP Options
With the evolvement of DHCP, new options come forth continuously. To utilize
these options, you can manually add them to the property list of a DHCP server.
