Configuring Address Allocation Mode For A Common Address Pool - HP 3600 v2 Series Configuration Manual

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.
To create a DHCP address pool:
Step
1. Enter system view.
2. Create a DHCP address pool
and enter its view.
Configuring address allocation mode for a common address
pool
IMPORTANT:
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 guidelines when you configure a static binding in a common address pool:
Use the static-bind ip-address command together with static-bind mac-address or static-bind
•
client-identifier to accomplish a static binding configuration.
• In a DHCP address pool, if you execute the static-bind mac-address command before the
static-bind client-identifier command, the latter will overwrite the former and vice versa.
If you use the static-bind ip-address, static-bind mac-address, or static-bind client-identifier
•
command repeatedly in the DHCP address pool, the new configuration will overwrite the previous
one.
The IP address of the static binding cannot be an interface address of the DHCP server. Otherwise,
•
an IP address conflict may occur and the bound client cannot obtain an IP address correctly.
The ID of the static binding must be identical to the ID displayed by using the display dhcp client
•
verbose command on the client. Otherwise, the client cannot obtain an IP address.
The lease duration can be specified and takes effect for a static binding, but the lease duration from
•
the display dhcp server ip-in-use all command output is still Unlimited.
• When the device serves as a DHCP client or BOOTP client, you must bind the DHCP client's ID to
an IP address, or bind the BOOTP client's MAC address to an IP address on the DHCP server.
Otherwise, the DHCP or BOOTP client cannot obtain a static IP address.
