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 address allocation mode for a common address
pool
CAUTION:
You can configure either a static binding or dynamic address allocation for a common address pool, but
not both.
You need to specify a subnet for dynamic address allocation. A static binding is a special address pool
containing only one IP address.
Configuring static address allocation
Some DHCP clients, such as a WWW server, need fixed IP addresses. To provide a fixed IP address, you
can create a static binding of a client’s MAC address or client ID to an IP address in the DHCP address
pool. A static binding is a special address pool containing only one IP address.
When the client with that MAC address or client ID requests an IP address, the DHCP server will assign
the IP address from the binding to the client.
Follow these steps to configure a static binding in a common address pool:
