Parameters

Parameter

Description

subnet <Subnet Entry>

Specifies the IPv4 address of the DHCP subnet on an Ethernet interface of the GaiaClosed Check Point security operating system that combines the strengths of both SecurePlatform and IPSO operating systems. device. Hosts behind the Gaia interface get IPv4 addresses from address pools in the subnet.

For example: 192.0.2.0

netmask <Mask>

Specifies the IPv4 subnet mask in CIDR notation.

For example: 24

include-ip-pool start <First IPv4 Address> end <Last IPv4 Address>

Specifies the IPv4 address that starts and the IPv4 address that ends the included allocated IP Pool range.

For example: 192.0.2.20 and 192.0.2.90

exclude-ip-pool start <First IPv4 Address> end <Last IPv4 Address>

Specifies the IPv4 address that starts and the IPv4 address that ends the excluded allocated IP Pool range.

For example: 192.0.2.155 and 192.0.2.254

include-ip-pool <First IPv4 Address-Last IPv4 Address>

Specifies the range of IPv4 addresses to include in the IP pool.

For example: 192.0.2.20-192.0.2.90

exclude-ip-pool <First IPv4 Address-Last IPv4 Address>

Specifies the range of IPv4 addresses to exclude from the IP pool.

For example: 192.0.2.155-192.0.2.254

enable

Enables the DHCP Server subnet, or the DHCP Server process (depending on the context).

disable

Disables the DHCP Server subnet, or the DHCP Server process (depending on the context).

default-lease <Lease in Seconds>

Specifies the default DHCP lease in seconds, for host IPv4 addresses. Applies only if DHCP clients do not request a unique lease time. If you do not enter a value, the default is 43,200 seconds.

max-lease <Maximal Lease in Seconds>

Specifies the maximal DHCP lease in seconds, for host IPv4 addresses. This is the longest lease available. If you do not enter a value, the configuration default is 86,400 seconds.

default-gateway <Default Gateway IPv4 Address>

Optional. Specifies the IPv4 address of the default gateway for the network hosts

domain <Domain Name for the DHCP Clients>

Optional. Specifies the domain name of the network hosts.

For example: example.com

dns <DNS Server IPv4 Address>

Optional. Specifies the DNS servers that the network hosts will use to resolve hostnames. Optionally, specify a primary, secondary and tertiary server in the order of precedence.

For example: 192.0.2.101, 192.0.2.102, 192.0.2.103

all

Shows all DHCP Server's configuration settings.

subnets

Configures the DHCP Server subnet settings.

subnet <Subnet Entry> ip-pools

The IP addresses pools in the DHCP Server subnet, and their status: Enabled or Disabled.

status

The status of the DHCP Server process: Enabled or Disabled.
