Configuring Dynamic Address Allocation For An Extended Address Pool - HP 830 Series Configuration Manual

Step
5. Specify the lease duration for the
IP address.
Configuring dynamic address allocation
For dynamic address allocation, you must 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 common address pool view, using the network command repeatedly overwrites the previous
configuration.
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.
• Using the dhcp server forbidden-ip command repeatedly 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 address lease
duration.
5. Return to system view.
6. Exclude IP addresses from
automatic allocation.
Configuring dynamic address allocation for an extended
address pool
Extended address pools support dynamic address allocation only.
When configuring an extended address pool, you must specify:
