Configuring the DHCP Server
7.5 Using DHCP GUI to Configure DHCP
• X Window Parameters
For any parameter, list the values in order of preference.
7.5.3.4.1 Name/ID parameters Name and identification parameters determine
the name of the configuration and information that identifies which client or
clients are being configured by this record.
Name
Specifies the name for this subnet, node, or include group configuration. The
names used here are tags for the internal use of the DHCP server. You can name
them as you choose but do not use the same name more than once except where
you use a different vendor class for the duplicate names.
Group Members
Specifies the names of subnet, node, and include groups that are members of the
group (that is, those that inherit this group’s parameters).
Member of Group
Specifies the name of the group that the subnet, node, or include group is joining.
7.5.3.4.1.1 Limitations on Group Hierarchies
The hierarchies provided for with member groups do not support multiple
inheritance. An include group can have multiple members, but an include,
subnet, or node group can be a member of only one group. For example, you
can make Group_A with members Group_B and Group_C, but you can not make
Group_A a member of Group_B and Group_C.
7.5.3.4.2 Key Parameters Key parameters identify the keys for the
configuration record. The Key parameters include Hardware Address/Client
ID, Hardware Type, Net or Subnet IP Address, and Vendor Class.
Hardware Address/Client ID
This parameter specifies the hardware address (MAC address) of the node.
Enter the hardware address in the format xx:xx:xx:x:xx:xx, for example,
00:08:C7:08:E3:63. The hardware address is assigned during manufacturing
and usually is displayed when you turn on or reboot your workstation.
Hardware Type
This field takes a string of characters and specifies the network type associated
with this node, such as Ethernet or token ring.
Enter either the symbol or the actual number as shown in Table 7–6. For
example, to specify Ethernet as the hardware type, enter either the symbol
ether or the number 1.
Net or Subnet IP Address
Specifies the address of the subnet record (if its a Subnet configuration record).
Enter the IP address that identifies this subnet portion of the network, for
example, 129.84.3.0.
Vendor Class
A DHCP client can pass a vendor class string to the server to identify the client
vendor implementation. For example, TCPVMS for the TCP/IP Services DHCP
client. The DHCP server uses the vendor class string as part of the key lookup
when determining which groups of configured parameters apply to the client. The
information is a string of octets, usually ASCII, that the server interprets.
