Creating a static mapping

Situations exist in which it makes sense to map a specific IP address to a specific host rather than dynamically assign an IP address from a pool of addresses. This mapping is known as a “static mapping.”

A static mapping is defined by using the static-mapping option of the service dhcp-server configuration node. The following example shows how to create a static mapping by associating the 172.16.0.101 IP address to the device with a MAC address of 00:15:c5:b3:2e:65.

Table 1. Creating a static mapping

Step

Command

Create a static mapping called lab and specify the static IP address.


vyatta@R1# set service dhcp-server static-mapping lab ip-address 172.16.0.101

Specify the associated MAC address within the lab static mapping.


vyatta@R1# set service dhcp-server static-mapping lab mac-address 00:15:c5:b3:2e:65

Commit the changes.


vyatta@R1# commit

Show the configuration.


vyatta@R1# show service dhcp-server
	static-mapping lab {
     ip-address 172.16.0.101
     mac-address 00:15:c5:b3:2e:65
 }
