Configuring DHCP
The DHCP (Dynamic Host Configuration Protocol) protocol enables a DHCP client who has not
set the IP address to set the IP address automatically.
NBG440 supports the following two functions: a DHCP relay function that delivers the IP address
request packet received from the DHCP client to the specified DHCP server, and a DHCP server
function that allocates the IP address upon the receipt of the IP address request packet. With these
functions, the DHCP client can access to the IP network without setting the IP address.
Setting DHCP relay service
To set up dhcp relay, you have to set the following command :
COMMAND
(conf)# dhcp relay to <server>
(conf)# dhcp relay off
Parameters
<server > - IP address of DHCP server
Usage Examples:
(conf)# dhcp relay to 168.126.188.30
To delete dhcp relay, you have to set the following command:
COMMAND
(conf)# dhcp relay off
Setting up a DHCP Server
Step1:
Setting the IP address pool :
To assign IP addresses dynamically, set the IP address pool. Possible to set up multiple
pools, but the overlapping of the range of IP for each pool is not allowed.
COMMAND
(conf)# dhcp add <poolname> <startip> <endip> <mask>
Parameters
<poolname> - name of the IP address pool
<startip> - start address of the IP address pool
<endip> - last address of the IP address pool
<mask> - subnet mask of the IP address pool
