Perle Systems SCS, STS manual Connecting to the Iolan Using DHCP/BOOTP

DHCP/BOOTP

DHCP/BOOTP

Overview

Several IOLAN parameters can be configured through a DHCP/BOOTP server during the IOLAN bootup. This is particularly useful for configuring multiple IOLANs.

Not all configuration parameters are supported in the DHCP/BOOTP configuration (see DHCP/BOOTP Parameters on page 56 for supported configuration parameters), so you will need to use another configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.

Unique Features

DHCP/BOOTP supports the following unique features:

zDHCP/BOOTP can supply the IOLAN’s IP address.

zThe DHCP/BOOTP server can configure certain server and user configuration parameters when the IOLAN is booted.

zThe DHCP/BOOTP server can auto-configure the IOLAN with basic setup information (IP address, subnet/prefix bits, etc.).

zThe DHCP/BOOTP server can download a new version of firmware when the IOLAN is rebooted.

zThe DHCP/BOOTP server can download a full configuration file when the IOLAN is rebooted.

Connecting to the IOLAN Using DHCP/BOOTP

The IOLAN will automatically request an IP address from the DCHP/BOOTP server when the Obtain IP address automatically using DHCP/BOOTP parameter is enabled. To enable the Obtain IP address automatically using DHCP/BOOTP parameter, follow the directions in Using a Direct Serial Connection to Enable BOOTP/DHCP on page 68.

Using DHCP/BOOTP

To use DHCP/BOOTP, edit the bootp file with IOLAN configuration parameters. You can use DHCP/BOOTP to perform the following actions on a single or multiple IOLANs on bootup:

zauto-configure with minimal information; for example, only an IP address

zauto-configure with basic setup information (IP address, subnet/prefix bits, etc.)

zdownload a new version of firmware

zdownload a full configuration file

DHCP/BOOTP is particularly useful for multiple installations: you can do all the IOLANs’ configuration in one DHCP/BOOTP file, rather than configure each IOLAN manually. Another advantage of DHCP/BOOTP is that you can connect the IOLAN to the network, turn on its power and let autoconfiguration take place. All the configuration is carried out for you during the DHCP/BOOTP process.
