Instructions

If you just moved the data domain to a new site and want to reconfigure everything new you can also run the config setup command. 

If you want to configure only the network then skip the config setup command, and just use the net commands from this kb. 

# config setup

Launch a utility program that prompts you to configure settings for the system, network, filesystem, CIFS, NFS, and licenses. Press Enter to cycle through the selections and confirm any changes when prompted. Choices include Save, Cancel, and Retry.

This command option is unavailable on Retention Lock Compliance systems. Use System Manager to change configuration settings. Role required: admin and limited-admin.
The net config command allows you to configure a physical interface on the DD.  
 # net config <ifname> [type {floating | fixed}]
                {[<ipaddr>] [netmask <mask>] | [<ipv6addr>] |
                [dhcp {yes [ipversion {ipv4|ipv6}]|no}]}
                {[autoneg] | [duplex {full | half} speed {10|100|1000|10000}]}
                [up | down] [mtu {<size> | default}]
                [txqueuelen <size>]
                                       Configure an Ethernet interface. Create
                                       an alias by giving an address to a new
                                       alias number. Destroy an alias by
                                       giving an address of zero. "Note:
                                       Change of link parameters like speed,
                                       duplex or autoneg on the DD VE is not
                                       supported."

Example # net config ethXx x.x.x.x netmask x.x.x.x 

To clear a interface give a address of zeros. 

Example # net config ethXx 0.0.0.0

If you need to change the default gateway on the data domain for a first time setup or moved the data domain to a new location the net route set gateway command can be used. 

Note: Caution when setting the default gateway remotely as you can lose complete access to the data domain. It is best using this command when you are in the idrac command console or directly serial connected to the DD on site at the data center.  
# net route set gateway {<ipaddr> | <ipv6addr>}
                                       Set the default gateway
If you just need to add a gateway you can use the net route add gateway command.  
# net route add gateway <ipv4addr> [interface <name>]
                                       Add a default gateway address,
                                       optionally to a specific interface
Note: net aggregate commands are unavailable for dd3300 since it does not support aggregation only failover.
