System > DHCP Auto Configuration
This page allows you to enable the DHCP Auto Configuration feature on the Switch. When enabled, the
Switch becomes a DHCP client and gets the configuration file from a TFTP server automatically on next boot
up. To accomplish this, the DHCP server must deliver the TFTP server IP address and configuration file
name information in the DHCP reply packet. The TFTP server must be up and running and store the
necessary configuration file in its base directory when the request is received from the Switch.

BOOTP Relay State: This field can be toggled between Enabled and Disabled using the pull-down menu. It
is used to enable or disable the DHCP/BOOTP Relay service on the Switch. The default is Disabled.
BOOTP Relay Hops Count Limit (1-16): This field allows an entry between 1 and 16 to define the
maximum number of router hops DHCP/BOOTP messages can be forwarded across. The default hop count
is 4.
BOOTP Relay Time Threshold (0-65535): Allows an entry between 0 and 65535 seconds, and defines the
maximum time limit for routing a DHCP/BOOTP packet. If a value of 0 is entered, the Switch will not process
the value in the seconds field of the BOOTP or DHCP packet. If a non-zero value is entered, the Switch will
use that value, along with the hop count to determine whether to forward a given BOOTP or DHCP packet.
