13.2.3 DHCP Setting Commands

This table lists DHCP setting commands. DHCP is based on DHCP pools. Create a DHCP pool if you
want to assign a static IP address to a MAC address or if you want to specify the starting IP address
and pool size of a range of IP addresses that can be assigned to DHCP clients. There are different
commands for each configuration. Afterwards, in either case, you have to bind the DHCP pool to the
interface.

pools.
Shows the specified DHCP pool's DHCP extended option settings.
Renames the specified DHCP pool from the first profile_name to the
second profile_name.
Creates a DHCP pool if necessary and enters sub-command mode.
You can use the DHCP pool to create a static entry or to set up a
range of IP addresses to assign dynamically.
About the sub-command settings:
• If you use the command, the ZyWALL / USG treats this
host
DHCP pool as a static DHCP entry.
• If you do not use the
host
command, the ZyWALL / USG treats this DHCP pool as a pool of IP
addresses.
• If you do not use the
host
command, the DHCP pool is not properly configured and cannot
be bound to any interface.
The command removes the specified DHCP pool.
