HP 10500 Series Configuration Manual page 49

If the interfaces on a DHCP client share the same MAC address, specify the client ID, rather than
•
MAC address, in a static binding to identify the requesting interface. If you do not specify the client
ID, the client may fail to obtain an IP address.
To configure a static binding in a common address pool:
Step
1. Enter system view.
2. Enter common address pool view.
3. Specify the IP address.
4. Specify the MAC address or client
ID.
5. Specify the lease duration for the
IP address.
Configuring dynamic address allocation
For dynamic address allocation, configure a DHCP address pool, specify one and only one address
range for the pool, and specify the lease duration. A DHCP address pool can have only one lease
duration.
To avoid address conflicts, configure the DHCP server to exclude IP addresses used by the gateway or
FTP server from dynamic allocation.
Follow these guidelines when you configure dynamic address allocation:
In a common address pool, if you use the network or network ip range command multiple times,
•
the most recent configuration takes effect.
• After you exclude IP addresses from automatic allocation by using the dhcp server forbidden-ip
command, neither a common address pool nor an extended address pool can assign these IP
addresses through dynamic address allocation.
You can exclude multiple IP address ranges from allocation.
•
To configure dynamic address allocation for a common address pool:
Step
1. Enter system view.
2. Enter common address pool
view.
3. Specify a subnet.
4. Specify the IP address range
on the subnet for dynamic
allocation.
