ip IP-ADDRESS
Default
None.
Command Mode
DHCP Pool Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command configures DHCP options in a DHCP pool. DHCP options can also be configured by other
commands such as the default-router command in the DHCP Pool Configuration Mode. The DHCP
server will carry all the configured DHCP options in all reply packets. All of the configured DHCP options
will be carried in the DHCP packet replied by the server.
The length of the configured hexadecimal string must be even (For example, 001100 is correct and 11223
is incorrect). Only one string can be specified for the same option number.
There is a restriction on the total length of DHCP options. The restriction may be specified by the client or
determined by the server if the client didn't specify this. If not specified, then the maximum length is 312.
The following options can be configured by other DHCP pool configuration mode commands and should
not be configured by the option command.
•
Option 1 (Subnet Mask, configured by the network).
•
Option 3 (Router Option, configured by the default router).
•
Option 6 (Domain Name Server, configured by the DNS server).
•
Option 15 (Domain Name, configured by the domain name).
•
Option 44 (NetBIOS Name Server, configured by the NetBIOS name server).
•
Option 46 (NetBIOS Node Type, configured by the NetBIOS node type).
•
Option 51 (IP Address Lease Time, configured by the lease).
•
Option 58 (Renewal (T1) Time Value, configured by the lease).
•
Option 59 (Rebinding (T2) Time Value, configured by the lease).
The following options cannot be configured through this command:
•
Option 12 (Host name default option).
•
Option 50 (Requested address, default option).
•
Option 53 (DHCP Message Type, default option).
•
Option 54 (Server Identifier, default option).
•

•
Option 61 (Client Identifier, default option).

Example
This example shows how to specify the DHCP server Option 69 (SMTP server option) in the hexadecimal
format. The hexadecimal string is c0a800fe (192.168.0.254).
Switch# configure terminal
Switch(config)# ip dhcp pool pool1
Switch(config-dhcp-pool)# option 69 hex c0a800fe
This example shows how to specify the DHCP server Option 40 (the name of the client's NIS domain) in
the ASCII string format.
Switch# configure terminal
Switch(config)# ip dhcp pool pool1
Switch(config-dhcp-pool)# option 40 ascii net.market
