Configure a network interface to use DHCP. Using DHCP will automatically update the Luna appliance's system name servers and other network settings that are transmitted via DHCP.
CAUTION! Do not specify DHCP if you intend to use network interface port bonding - a change to the leased IP address disrupts port bonding, which must be manually disabled and then reconfigured before it can be re-enabled.
NOTE When DHCP is used, the appliance's IP address may change automatically, which may lead to certificate mismatches and client connection issues.
You cannot configure an interface that is a member of an active bond. You must first disable the bond. See network interface bonding
NOTE Running this command changes the interface state and causes the ctc service to restart (see Crypto Traffic Controller for QoS).

Example
DHCP with IPv4
lunash:>network interface dhcp -device eth1
NOTICE: The network connection for device eth3 will be restarted for new network settings to take effect.
If you are sure that you wish to restart the device connection, then type 'proceed', otherwise type 'quit'
> proceed
