DHCP Client Configuration

The DHCP Client uses the following global constants, which an application can modify at run-time before calling xn_dhcp:

CFG_DHCP_RETRIES

Number of times the DHCP Client should retry when no response from a DHCP server is received. Default is 1.

CFG_DHCP_TIMEOUT

Number of seconds to wait for a server response. Default is 4 seconds.

CFG_DHCP_BROADCAST

Default: 0. If set to one, the DHCP client will send DHCP REQUESTs as broadcasts instead of to the DHCP Server's IP address.

CFG_DHCP_SERVER_IP_OPT

Default: 0. If set to one, the DHCP client will extract the DHCP server IP address from the DHCP OFFER Server IP option rather than use the address the OFFER was sent from.

CFG_DHCP_OFFERS

Default: 1. This parameter specifies for how many DHCP_OFFER messages the DHCP client should wait before selecting one. CFG_DHCP_OFFERS can be set to any value >= 1.
