Setup iLO Network Settings via ipmitool

Need to configure the network settings for HP's Integrated Lights Out management controller? If you have an OS installed or a live CD/image with ipmitool installed, here's how to do that - remotely!

For this example, we'll be using ipmitool v1.8.15 on ESXi 6.5.0 on an HP ProLiant DL360 G7. This should, however, work with any installation of ipmitool, on any OS or hardware.

First, SSH to the host or open a console.
Second, we'll list the current settings. The channel for this iLO port is 2. You may need to change that value.
```
ipmitool lan print 2
```

As you can see from the output, it is set to DHCP.

                        :     c=CALLBACK
                        :     u=USER
                        :     o=OPERATOR
                        :     a=ADMIN
                        :     O=OEM

We'll set the following values:

Description	Command
Change to static assignment	`ipmitool lan set 2 ipsrc static`
Set IPv4 address	`ipmitool lan set 2 ipaddr 192.168.1.100`
Set subnet mask	`ipmitool lan set 2 netmask 255.255.255.0`
Set gateway (next-hop)	`ipmitool lan set 2 defgw ipaddr 192.168.1.1`
Set VLAN ID (if tagging traffic)	`ipmitool lan set 2 vlan id 1001`

Lastly, you may need to reset the iLO for the changes to take:
```
ipmitool mc reset cold
```
