Creating a DHCP server on Interface BACKPLANE0 in Nodegrid

Creating a DHCP server on Interface BACKPLANE0 in Nodegrid


To configure and enable the DHCP server in Nodegrid Manager:


1. Add a subnet


From the Web UI:


  1. Click on the Network icon and select DHCP from the menu bar
  2. Click Add to create a DHCP range



Click on Add and fill in the Subnet, Network and Router IP (BACKPLANE0 IP in this case, normally the first IP of the network):



Click on Save to save your settings

To set up the DHCP range from the command line:


  1. Log in as the admin user to access the Nodegrid command line
  2. If you are logged in as root user, you can ‘su – admin’ and then type ‘cli’
  3. In the Nodegrid command line, cd /settings/dhcp_server
  4. Type ‘show’ to display any existing dhcp ranges
  5. Type ‘add’ to go into the dhcp configuration mode
  6. Type ‘set subnet=<your ip subnet>’




Type in the netmask:


‘set netmask=<your subnet netmask>’






Type ‘save’ and the DHCP server is ready for use


2. Set the IP range:


      1. Select the Network icon
      2. Select 'DHCP -> DHCP server' on the navbar
      3. Select the DHCP Server previously created. Select 'Network Range' in the grey navbar.

Input the starting (lowest) and ending (highest) numbers of your DHCP range within the current subnet.
Click Save.



To add a DHCP range from the command line:

cd /settings/dhcp_server/
show

If there are any configured ranges, they will be listed by the show command.

cd to any listed IP subnet name that you want to add a range to and append '/network_range':

cd 10.10.1.10|255.255.255.240/network_range/

Type 'show' to list any available network ranges.

Type 'add' to add a network range


In this example, the start ip address is 10.10.1.100 and the end address is 10.10.1.200

set ip_address_start=10.10.1.100
set ip_address_end=10.10.1.200

save

once the range has beed added and saved, you can type 'show' to list the range:

[admin@nodegrid {network_range}]# show
ip_address_start = 10.10.1.100
ip_address_end = 10.10.1.200
[admin@nodegrid {network_range}]#
