Creating A Dhcp Address Pool; Configuring Address Allocation Mode For A Common Address Pool - HP 10500 Series Configuration Manual

Creating a DHCP address pool

When creating a DHCP address pool, specify it as a common address pool or an extended address pool.
Address allocation mode is configured differently for common address pools and extended address
pools. Configurations of other parameters (for example, the domain name suffix and DNS server address)
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
CAUTION:
You can configure either a static binding or dynamic address allocation for a common address pool, but
not both.
You must 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 for
such a client, statically bind the MAC address or ID of the client to an IP address in a DHCP address pool.
When the client requests an IP address, the DHCP server assigns the IP address in the static binding to
the client.
Follow these guidelines when you configure static address allocation:
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 overwrites the former and vice versa.
If you use the static-bind ip-address, static-bind mac-address, or static-bind client-identifier
•
command multiple times in the DHCP address pool, the most recent configuration takes effect.
• The IP address of the static binding cannot be an interface address of the DHCP server. Otherwise,
an IP address conflict could occur, making 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 specified lease duration takes effect but the lease duration displayed by the display dhcp server
•
ip-in-use all command is still Unlimited.
When the device serves as a DHCP client, bind the DHCP client's ID to an IP address on the DHCP
•
server.
