TCP/IP Network Settings

From the Network Settings, configure the TCP/IP network settings as follows:

Automatic IP Configuration

DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol that lets network administrators centrally manage and automate the assignment of IP addresses in an organization's network. Check the box to allow a DHCP server on the network to assign the IP address.

Important!

DHCP should only be enabled if you are using dynamic IP address notification, or if your version of DHCP can update a DNS server, which then allows you to access the AXIS 250S by name. If DHCP is enabled and you cannot access the unit, you may have to reset it to the factory default settings (see page 34) and then perform the installation again (see page 10).

BOOTP - Check this box to use BOOTP to automatically assign an IP address. Requires a BOOTP server on your system. BOOTP is enabled by default and is required for installation using the AXIS IP Installer.

Dynamic IP Address Notification Settings

When the IP address changes by means beyond your control, for example, by DHCP, you can choose to be notified of the change via HTTP, FTP or SMTP. Click the icon to display, edit and refine the settings for address notification.

Referring to the table below, configure the dynamic IP address notification settings.

Parameter	Description
HTTP	Enabling HTTP means the server will send an HTTP GET request to the specified URL. This can then easily
	be taken care of by a designated cgi-script, which registers the request by some means. Custom
	parameters can be used by entering them in the field provided. The fields User Name and Password, should
	be used if the script is password protected. If you need to pass a proxy server to connect to the URL for the
	host, provide your user information in the relevant fields.
SMTP	Enabling SMTP will send an email notification of any change in IP address. Enter the recipient’s address
	and a sender’s address, as well as any text you want to appear in the subject of the email. Note that you
	must configure the mail server under Network Settings.
FTP	Saves a notification file on an FTP server. Provide the connection details for the server and your user name
	and password. If there is a firewall between the server and the FTP server, it is recommended that Passive
	Mode is enabled. There are 3 levels of TXT Type to choose from; Short - the IP address only; Extended -
	multi-line file; and HTML - contains the same information as Extended, but includes HTML tags. See also
	the On-line help for more information.
TXT Field	Specify your own text to include in the notification.
