Configuring Dynamic Address Allocation For An Extended Address Pool - HP A5120 EI Series Configuration Manual

To do...
Exclude IP addresses from
automatic allocation
NOTE:

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.
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:
Assignable IP address range

Mask

After the assignable IP address range and the mask are specified, the address pool becomes valid.
Follow these steps to configure dynamic address allocation for an extended address pool:
To do...
Enter system view
Enter extended address pool

Specify the IP address range
Specify the IP address mask
Specify the IP address range for
the DHCP clients of a specified
