DES-7200 Configuration Guide Chapter 4 DHCP Configuration
4-9
By default, the Windows operation systems support broadcast or hybrid type
NetBIOS nodes. If no WINS server is configured, the node is of broadcast type.
If a WINS server is configured, the node is of hybrid type.
To configure the NetBIOS node type for the DHCP client, execute the following
command in the address pool configuration mode:
Command Function
DES-7200(dhcp-config)#
netbios-node-type type
Configure the NetBIOS node type.
4.5.3.9 Configuring the Network
Number and Mask of the
DHCP Address Pool
To configure dynamic address binding, you must configure the subnet and its
mask for the new address pool. A DHCP address pool provides the DHCP
server with an address space that can be assigned to clients. All the addresses
in the address pool are available for the DHCP clients unless address exclusion
is configured. The DHCP server assigns the addresses in the address pool in
sequence. If an address already exists in the binding table or this address is
detected to be already present in this network segment, the DHCP server will
check the next address until it assigns a valid address.
To configure the subnet and its mask of the DHCP address pool, execute the
following commands in the address pool configuration mode:
Command Function
DES-7200(dhcp-config)# network
network-number mask
Configure the network number and mask of
the DHCP address pool.

For the DHCP dynamic address pool of DES-7200 products,
addresses are assigned based on the physical address and ID of
a DHCP client. This means there should not be two leases for the
same DHCP client in the DHCP dynamic address pool. If path
redundancy occurs between the DHCP client and the DHCP
server (the DHCP client can reach the DHCP server by the direct
path or relay path), the DHCP server may fail to assign addresses.
To solve this problem, administrators should avoid path
redundancy between the DHCP clients and the DHCP sever in
other ways like adjusting physical links or network paths.
