DHCP Configuration Task List
8 Release 12.0(1)T
To configure manual bindings, use the following commands beginning in global configuration mode:
Configuring a DHCP Server Boot File
The boot file is used to store the boot image for the client. The boot image is generally the operating
system the client uses to load. To specify a boot file for the DHCP client, use the following command
in DHCP pool configuration mode:
Configuring the Number of Ping Packets
By default, the DHCP server pings a pool address twice before assigning the address to a requesting
client. If the ping is unanswered, the DHCP server assumes (with a high probability) that the address
is not in use and assigns the address to the requesting client. To change the number of ping packets
the DHCP server should send to the pool address before assigning the address, use the following
command in global configuration mode:
Step Command Purpose
1 Router(config)# ip dhcp pool name Creates a name for the a DHCP server address
pool and places you in DHCP pool configuration
mode—identified by the (config-dhcp)# prompt.
2 Router(config-dhcp)# host address [mask |
/prefix-length] Specifies the IP address and subnet mask of the
client.
The prefix length specifies the number of bits that
comprise the address prefix. The prefix is an
alternative way of specifying the network mask of
the client. The prefix length must be preceded by
a forward slash (/).
3 Router(config-dhcp)# hardware-address
hardware-address type
or
Router(config-dhcp)# client-identifier
unique-identifier
Specifies a hardware address for the client.
Specifies the distinct identification of the client in
dotted-hexadecimal notation, for example,
01b7.0813.8811.66, where 01 represents the
Ethernet media type.
4 Router(config-dhcp)# client-name name (Optional) Specifies the name of the client using
any standard ASCII character. The client name
should not include the domain name. For
example, the name mars should not be specified
as mars.cisco.com.
Command Purpose
Router(config-dhcp)# bootfile filename Specifies the name of the file that is used as a boot image.
Command Purpose
Router(config)# ip dhcp ping packets
number Specifies the number of ping packets the DHCP server sends to
a pool address before assigning the address to a requesting cli-
ent. The default is two packets.
