Creating a DHCP Address Pool
When creating a DHCP address pool, specify it as a common address pool or an extended address
pool.
Follow these steps to create a DHCP address pool:
To do… Use the command… Remarks
Enter system view system-view —
Create a DHCP address pool and
enter its view dhcp server ip-pool pool-name
[ extended ]
Required
No DHCP address pool is created by
default.
NOTE:
A common address pool and an extended address pool are different in address allocation mode
configuration. Configurations of other parameters (such as the domain name suffix and DNS server
address) for them are the same.
Configuring an Address Allocation Mode for a Common
Address Pool
CAUTION:
You can configure either the static binding or dynamic address allocation for a common address pool as
needed.
It is required to specify an address range for the dynamic address allocation. A static binding is a special
address pool containing only one IP address.
Configuring manual address allocation
Some DHCP clients such as a WWW server need fixed IP addresses. You can create a static binding of
a client’s MAC or ID to IP address in the DHCP address pool.
When the client with the MAC address or ID requests an IP address, the DHCP server will find the IP
address from the binding for the client.
A DHCP address pool now supports only one static binding, which can be a MAC-to-IP or ID-to-IP
binding.
Follow these steps to configure a static binding in a common address pool:
To do… Use the command… Remarks
Enter system view system-view —
Enter common address pool view dhcp server ip-pool pool-name —
Specify the IP address of the binding
static-bind ip-address ip-address
[ mask-length | mask mask ]
Required
No IP addresses are statically
bound by default.
Specify the
MAC address
Specify the MAC
address
static-bind mac-address
mac-address

the two
