Chapter 59 Configuring the Cisco IOS DHCP Server
Configuring DHCP Address Pools
Step 8
Switch(dhcp-config)# dns-server address
[ address2 ... address8 ]
Specifies the IP address of a DNS server that is available to a
DHCP client.
•
One IP address is required; however, you can specify up to
eight IP addresses in one command.
• Servers should be listed in order of preference.
Step 9
Switch(dhcp-config)# bootfile filename (Optional) Specifies the name of the default boot image for a
DHCP client.
•
The boot file is used to store the boot image for the client. The
boot image is generally the operating system that the client
uses to load.
Step 10
Switch(dhcp-config)# next-server address
[ address2 ... address8 ]
(Optional) Configures the next server in the boot process of a
DHCP client.
•
One address is required; however, you can specify up to eight
addresses in one command line.
• If multiple servers are specified, DHCP assigns them to
clients in a round-robin order. The first client gets address 1,
the next client gets address 2, and so on.
•
If this command is not configured, DHCP uses the server
specified by the i
p helper address command as the boot
server.
Step 11
Switch(dhcp-config)# netbios-name-server
address [ address2 ... address8 ]
(Optional) Specifies the NetBIOS WINS server that is available
to a Microsoft DHCP client.
• One address is required; however, you can specify up to eight
addresses in one command line.
•
Servers should be listed in order of preference.
Step 12
Switch(dhcp-config)# netbios-node-type
type
(Optional) Specifies the NetBIOS node type for a Microsoft
DHCP client.
Step 13
Switch(dhcp-config)# default-router
address [ address2 ... address8 ]
(Optional) Specifies the IP address of the default device for a
DHCP client.
•
The IP address should be on the same subnet as the client.
• One IP address is required; however, you can specify up to
eight IP addresses in one command line. These default
devices are listed in order of preference; that is, address is the
most preferred device, address2 is the next most preferred
device, and so on.
•
When a DHCP client requests an IP address, the
device—acting as a DHCP server—accesses the default
device list to select another device that the DHCP client will
use as the first hop for forwarding messages. After a DHCP
client has booted, the client begins sending packets to its
default device.
Step 14
Switch(dhcp-config)# option code
[ instance number ] { ascii string | hex
string | ip-address }
(Optional) Configures DHCP server options.
