DHCP Configuration
Use this form to set up and delete subnets, groups, IP pools, and hosts
and edit DHCP entries.
To add a new entry (subnet, group, IP pool, or workstation) to the configuration or
to delete an entry, select the desired action from the selection box next to the
entry and click Do Action. It is not possible to add entries
to pools and hosts; these can only be deleted.
Caution: When an entry is deleted, all subordinate entries
are also deleted.
To edit or add DHCP options or statements in an entry, click the respective
entry.
The following DHCP entries can be configured:
- Subnet
- This is the basic entry for the DHCP server.
This entry tells the DHCP server for which subnets with which IP address
masks it is responsible.
All other DHCP objects can be inserted in a subnet.
- Group
- Host names that are handled by the DHCP server with the
same DHCP parameters (options, statements) are merged to a group.
Only host objects can be added to a group. However, a group can be
member of the global configuration and of a subnet.
- IP Pool
- An address pool defines an IP address space that is to be
treated differently than the other IP addresses. When the DHCP pool is
created, the IP addresses in the IP pool are registered with the name server
and host names are generated for these IP addresses.
- Workstation
- To enter a host in the DHCP configuration, the host must first be
entered in the DNS configuration.
A host can be added to the base configuration, to a DHCP subnet,
or to a group.
- Important
-
At least one subnet must be configured to be able to start the DHCP server.
Changes to the DHCP server are saved into the LDAP server. Click Export
to create and reload the configuration of the DHCP server.
