DHCP Auto Configuration Settings

This window is used to enable the DHCP auto-configuration feature on the Switch. When enabled, the Switch is instructed to
receive a configuration file from a TFTP server, which will set the Switch to become a DHCP client automatically on boot up. To
employ this method, the DHCP server must be set up to 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 hold the necessary configuration file stored
in its base directory when the request is received from the Switch. For more information about loading a configuration file for use
by a client, see the DHCP server and/or TFTP server software instructions. The user may also consult the Upload screen
description located in the Maintenance section of this manual.
If the Switch is unable to complete the DHCP auto configuration, the previously saved configuration file present in the Switch's
memory will be used.
To view this window, click Administration > DHCP Auto Configuration Settings as shown below.
To enable the DHCP Auto Configuration State, use the pull-down menu to choose Enabled and click the Apply button.

DHCP/BOOTP Relay

The relay hops count limit allows the maximum number of hops (routers) that the DHCP/BOOTP messages can be relayed
through to be set. If a packet's hop count is more than the hop count limit, the packet is dropped. The range is between 1 and 16
hops, with a default value of 4. The relay time threshold sets the minimum time (in seconds) that the Switch will wait before
forwarding a BOOTP REQUEST packet. If the value in the seconds field of the packet is less than the relay time threshold, the
packet will be dropped. The range is between 0 and 65,536 seconds, with a default value of 0 seconds.
