Bright:Network settings

DHCP

To enable DHCP on Bright Cluster, we need to make sure that the lockdowndhcp property is set for that network.

# cmsh
% network use <network_name>
% set lockdowndhcpd no
% commit

Please note that a node is attached to a network by attaching aninterface to this node which is connected to that network. If you want to change the network of some nodes, you can do that by changing the network property of the interfaces attached to those nodes using the commands below:

# cmsh
% device
% foreach -n node001..node010 (interfaces; use eth1; set network
<new_network>; commit)

Change interface IP address
