On the router, DHCP is based on DHCP policies. Policies are predefined sets of
configuration information items. Each policy defines IP configuration
information for the clients that are attached to a single IP interface. Each policy
has at least one IP address range attached to it. A range is a list of consecutively
numbered IP addresses. When the DHCP server uses a policy to supply DHCP
information to a client, it assigns the client an unused IP address from the
policy's IP address ranges.
DHCP and its predecessor BOOTP are both supported, but are disabled by
default.
To configure the router as a DHCP server:
1. Enable IP and give the desired interface an IP address and subnet mask.
This IP address needs to be in the subnet that you wish to assign to hosts
that are connected to that interface. Use the commands:
ENABLE IP
ADD IP INTERFACE
If the interface is a VLAN, you may have to create it first.
2. Create a DHCP policy using the command:
CREATE DHCP POLICY=name LEASETIME={lease-time|INFINITY}
[INHERIT=name]
3. Assign an IP address range to the policy. This range must be in the same
subnet as the IP address that you assigned to the interface. Use the
command:
CREATE DHCP RANGE=name IP=ipadd NUMBER=number POLICY=name
[GATEWAY=ipadd]
4. Assign any other desired configuration settings to the policy, using the
command:
ADD DHCP POLICY=name [options...]
The server will use that policy on that interface. Repeat this process with as
many interfaces and policies as required.
5. Enable the DHCP server, using the command:
ENABLE DHCP
For more information on how to configure DHCP, see the Dynamic Host
Configuration Protocol (DHCP) chapter in the Software Reference.
