Task	At the NetScaler command prompt,
	type:

To release the DHCP IP address and	> release dhcpIP
return it to the IP address pool on the
DHCP server when the NetScaler
configuration is complete

Using DHCP When a Configuration File is Present

If you need to move a NetScaler appliance to a different subnet, such as from a testing environment to a production environment, you can use DHCP to access an appliance that already has a configuration file. Before moving the appliance, enable its DHCP client and save the configuration. As a result, when the appliance restarts, it automatically polls the DHCP server for an IP address. If you did not enable the DHCP client and save the configuration before shutting down the appliance, you will need to connect to the appliance through the console and dynamically run the DHCP client on the appliance. The DHCP server will then provide an IP address, a gateway, and a subnet mask. You can use the IP address to access the appliance and configure the other settings remotely.

If the DHCP client is enabled in the configuration file, you should disable it and then save the configuration file. If the DHCP client is enabled, the appliance will poll the DHCP server again for an IP address when it restarts.

The following table lists the NetScaler CLI commands associated with each task.

Table 4-3.NetScaler CLI commands for using DHCP with a previously configured NetScaler Appliance

Task	At the NetScaler command prompt,
	type:

To dynamically run the DHCP client to		> set dhcpParams dhcpClient on
fetch an IP address from the DHCP server

To configure the DHCP client to run when		> set dhcpParams dhcpClient on
the appliance restarts		> save config
		> save config

To prevent the DHCP client from running		> set dhcpParams dhcpClient off
when the appliance restarts		> save config
		> save config

		Note: This is required only if the ON
		setting was saved.
