Main Help Topics

This page configures the device for your network's BOOTP or DHCP servers for automatic assignment of IP addresses.

Settings

Configuration Server Protocol

Select your network's method of IP address assignment. This setting contains the following options:

• None -- Your network does not have an automatic system for IP address assignment.
• BOOTP -- Your network uses Boot Protocol, in which IP addresses are hard-coded based on MAC addresses.
• DHCP -- With Dynamic Host Configuration Protocol, IP addresses are leased for a period of time. You can set the lease duration with the settings on this page.

Use Previous Configuration Server Settings When No Server Responds?

Select yes to have the device save the boot server's most recent response. The device uses the most recent settings if the boot server is unavailable.

Read.ini File from File Server?

Use this setting to have the device use configuration settings in an .ini file on the BOOTP or DHCP server or the default file server. Files with .ini extensions usually contain configuration information used during system startup. The pull-down menu contains the following options:

• Always -- The device always loads configuration settings from an .ini file on the server.
• Never -- The device never loads configuration settings from an .ini file on the server.
• If specified by server -- The device loads configuration settings from an .ini file on the server if the server's DHCP or BOOTP response specifies that an .ini file is available.
• If specified by server -- The device loads configuration settings from an .ini file on the server if the server's DHCP or BOOTP response specifies that an .ini file is available. This is the default setting.

The Load Now button under the pull-down menu tells the device to read an .ini file immediately.

The Current Boot Server line under the pull-down menu lists the server that responded to the boot request. If all zeros appear, it means that the device is not using BOOTP/DHCP or that no server responded to the BOOTP/DHCP request. The Specified ".ini" File Server line lists the IP address of the server where the .ini file is stored. If all zeroes appear, it means that no file server is set up to provide an .ini file.

Current Boot Server

This is the server that responded to the boot request. If all zeros appear, the device is not using BOOTP/DHCP or no server responded to the BOOTP/DHCP request.

Specified ".ini" File Server

Lists the IP address of the server where the .ini file is stored. If all zeroes appear, it means that no file server is set up to provide an .ini file.

BOOTP Server Timeout (sec.)

Enter the length of time (in seconds) the device waits to receive a response from a single BOOTP server.

DHCP Multiple-Offer Timeout (sec)

Enter the length of time (in seconds) the device waits to receive a response when there are multiple DHCP servers.

DHCP Requested Lease Duration (min)

Enter the length of time (in minutes) the device requests for an IP address lease from your DHCP server.

DHCP Minimum Lease Duration (min)

Enter the shortest amount of time (in minutes) the device accepts for an IP address lease. The device ignores leases shorter than this period.

DHCP Client Identifier Type

Your DHCP server can be set up to send responses according to the class identifier type specified by the access point in the DHCP request packet. If most of the client devices using the access point are the same device type, you can select that device type to be included in the DHCP request packet.

The DHCP Client Identifier Type pull-down menu lists the following options:

• Ethernet (10Mb) -- Default
• Experimental Ethernet
• Amateur Radio AX.25
• Proteon ProNET Token Ring
• Chaos
• IEEE 802 Networks
• ARCNET
• Hyperchannel
• Lanstar
• Autonet Shot Address
• LocalTalk
• LocalNet
• Other-Non Hardware -- Select this option to include a unique value in the DHCP Client Identifier Value field.

DHCP Client Identifier Value

Use this setting to include a unique identifier in the access point's DHCP request packet. This field contains the access point's MAC address by default. If you select Other-Non Hardware from the DHCP Client Identifier Type pull-down menu, you can enter up to 255 alphanumeric characters. If you select any other option from the DHCP Client Identifier Type pull-down menu, you can enter up to 12 hexadecimal characters. Hexadecimal character include the numbers 0 through 9 and the letters A through F.

DHCP Class Identifier

Your DHCP server can be set up to send responses according to the group to which a device belongs. Use this field to enter the group name. The DHCP server uses the group name to determine the response to send to the device. The device's DHCP class identifier is a vendor class identifier.
