20.5.12 Configuring Network Number and
Mask for DHCP Address Pool
To configure dynamic address binding, you must configure the subnet and its mask for the
new address pool, so as to provide the DHCP server with an address space that can be
assigned to clients. All the addresses in the address pool may be assigned to 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 for the address pool, execute the following commands
in the address pool configuration mode:
Command
Function
DGS-3610(dhcp-config)# network
network-number mask
Configure the network number and mask for the
DHCP address pool
Caution
For the DHCP dynamic address pool of our product, the assignment of
the address takes the physical address of client and the client ID as the
index, which means there should not be two leases for the same client in
the DHCP dynamic address pool. If there is the redundant path on the
network topology between the client and server (the client can reach
servers by the direct path or by the relay path), it will cause the failure of
address assignment occurs and may fail to assign the address.
To avoid above problem, it requires the network manager takes other
methods to prevent the path redundancy from the client to server when
the network is established, such as adjust the physical link or the network
path.
20.5.13 Binding Address Manually
Address binding refers to the mapping relationship between the IP address and the MAC
address of the client. There are two types of address binding: 1) Manual binding, namely a
user define manually in the DHCP server database to statically map the IP address to the
MAC address. Manual binding is actually a special address pool; 2) Dynamic binding,
namely upon receiving a DHCP request, the DHCP server dynamically assigns an IP
address in the address pool to the client, thus mapping the IP address to the MAC address.
