Confi gure > DHCP Server > MAC –>IP Addresses 4.19
This page allows you to configure a number of MAC to IP address mappings and should be used
when it is necessary to supply a specific IP address to a particular Ethernet MAC address. This is
particularly useful for mobile applications, e.g. GPRS, where a particular piece of mobile equipment
is issued the same IP address no matter how long it has been since it was last connected to the
network.
Using the Web Page(s)
To configure an entry in the table simply enter the MAC addresses of the devices that you want
to allo cate a fixed IP addresses to in the left hand column and the required IP addresses in the
right hand column. It is important to ensure that the IP addresses used DO NOT fall within the IP
address ranges specified in the DHCP server page(s).
Using Text Commands
To configure NUI mappings from the command line use the mac2ip command.
To display a current mapping enter the command:
mac2ip <entry> ?
where <entry> is 0-9.
Two separate commands are needed to set up a mapping. These take the form:
mac2ip <entry> mac <MAC>
mac2ip <entry> ip <IP address>
where:
<entry> is the required entry number in the mapping table in each case
<MAC> is the MAC
<IP Address> is the IP address
