Managing DHCP on the Gateway appliance private network - version 1.10 and newer

[EcoStruxureIT]

The Ecostruxure IT Gateway appliance comes with a DHCP server configured and enabled by default on its private network (LAN2 or Gb2 port on the Gateway appliance depending on the model).

Access to the Gateway appliance network settings is available on its private network only.

Do not run more than one DHCP server on the private network.

If you are deploying the Gateway on a private network that already has a DHCP server, such as from a Data Center Expert server, you must disable the DHCP service on the Gateway or on the other device providing DHCP service.

If you change the Gateway appliance private network IP address, you must also log in to the CLI on the appliance private network to restart the DHCP server.

Editing DHCP server settings on the Gateway private network

Configure the DHCP server settings if the Gateway is going to provide DHCP services but you need to change the default settings. For example, change these settings if your private network uses a range of IP addresses different from the default.

Changes may require that you stop and restart the Gateway DHCP server. If you change the Gateway appliance default IP address to an address that is on a different network, you must also log in to the CLI on the appliance private network to restart the DHCP server.
