Option - HP A5120 EI Series Command Reference Manual

NOTE:

Only the extended address pools support this command.

If you specify an IP address range for an extended address pool without an IP address mask, the extended
address pool is not valid, and therefore the system cannot assign IP addresses from the extended address pool.
Related commands: dhcp server ip-pool, network ip range, and display dhcp server tree.
Examples
# Specify 255.255.255.0 as the IP address mask for dynamic allocation in extended address pool 0.
<Sysname> system-view
[Sysname] dhcp server ip-pool 0 extended
[Sysname-dhcp-pool-0] network mask 255.255.255.0
